okay guys welcome back so today we're going to be talking about the BMW B-57 reliability this has been a highly requested video as many of you guys own this engine and this is why I'm doing this video to tell you all about the common problems you're going to face you're going to have if you own the BMW B57 engine in your BMW so the first one I want to talk about is turbochargers on a B-57 so as many of you guys know there was a big big problem with the turbochargers on BMW Audi Volkswagen all over regarding the turbochargers and their wastegate rattle so many of you guys know they use an electronic wastegate actuator which can cause a lot of rattling and become very annoying for most people now as many of you guys know that wasn't a recall bmw didn't fix it for free the only way to rectify that is to buy a new wastegate now they are readily available out there to buy them they're electronic ones you can easily replace them they're only held on by four bolts and you can do it if you know what you're doing but some people don't and they just leave it and it becomes very very annoying not only that it can actually destroy your turbo because it's electronic it's not opening when the DME is requesting it to open when it's engaging the turbo so when it's trying to get rid of that atmospheric pressure from the turbo it can't that's what the waste gate is actually for it's not opening and closing because it's electronic therefore it can actually cause your turbo to fail that's never a good thing and that's why if you do any any rattling or any kind of when you rev up and you hear the rattling it's going to be your waste gate that's therefore I recommend you get it replaced they are electronic and like I said they are readily available get them replaced many of you guys with the B57 will be probably having that issue that's what you got to do to rectify the issue the next one on the BMW B57 is the high pressure fuel pump failing that's become very very common on the B57 and I've been seeing it a lot i've seen a lot of people having that failure a lot of the time for the high pressure fuel pump failing is not a cause of anyone else's there was just a bad design on the B-57 for the high pressure fuel pumps people do upgrade them and I know they do an upgraded one now for the B-57 engine because BMW's one was flawed and people are removing them and putting on an upgraded one purely for that reason there's nothing you can really do about it the only problem when the highpressure fuel pump goes is whatever damage has been done while it's been on there can end up damaging your injectors as well and it also end up damaging your DPF your EGR swell flaps everything on it because it's not running correctly and a lot of people don't notice it straight away they notice limp mode and reduce power and then they just try and get the light off or turn the engine off let it sit restart it and the problem goes away and that's where the problems start coming from is when people start doing that not fixing the problem straight away it leads to other problems especially on the diesels that's why if you are having any kind of problems with fuel pressure loss it will be your highpressure fuel pump get it checked out and get it replaced because as I said they are known to fail but on the B-57 it's very very common for them to fail so the next one on the BMW B-57 is the EGR cooler itself they can fail and it's due to a lot of heat and when they get hot they can actually damage the engine as well when they get overheated therefore make sure to be checking your EGR now the reason why these EGRs end up failing is usually because of a lot of people doing a lot of short journeys which is why they end up failing in the first place my best advice is do not do short journeys i would strongly advise if you're on a B-57 every week once a week take it on the motorway and give it the freshening it needs to clear out any junk out the EGR the next one is the DPF clogging now the diesel particulate filter as many of you guys know is used to burn off any kind of harmful chemicals or particles from the diesel engines a lot of the time them DPF can become clogged up from suit buildup and just people using them not for what they're intended to be used for for instance doing short journeys the DPF doesn't get a chance to heat up the glow plugs haven't heated up which hasn't which means the DPF ain't being able to burn off all the crap out the DPF which causes the DPFs to fail on them a lot of people as I said buy diesels and use them just to pot around town or go local do not buy diesel if you're doing that that is really really bad for the EGR and the DPF and that's where a lot of the problems come from with diesel engines especially on the B-57 it's relevant on the B-47 and B-37 if you own a B37 B-57 engine make sure to let it come up to temperature and make sure your glow plugs are working people don't realize how important the glow plugs are for a diesel especially on a later diesel the glow plugs help aid the burning process on the DPF to get rid of all the crap out the exhaust they're not functioning your DPF will clog up and your engine will just stop completely um running completely it will not run many people have experienced that a lot of people like to do away with it for remaps because they don't want to have to replace it the best thing I could tell you to not have to replace it is to make sure you're using your diesel the way it was intended to be used for long distance as I tell everyone if you're not doing 10 to 12,000 mi a year do not buy a diesel buy yourself a petrol it doesn't make sense a lot of people want it for the torque the power but you can get that in a petrol i don't understand if you want to power you buy an M car you don't need to go and buy um a diesel it doesn't make sense it does not make viable sense they are made for long distance driving long distance that's why BMW fit the EGR the DPF because people are going to be doing long distance with them not just pot into the shops poting 5 minutes down the road turn the engine off the engine doesn't even get time to heat up which if the engine doesn't heat up all that sue does not melt down and break down easily it becomes thick and stuck like tar to everything if you guys that don't know anything about mechanicals that is how a diesel works is very very thick like tar you can go and get your car walnut blasted but that is not going to solve the issue on um clearing out your DPF at all the best way to clear that is to run the engine up to temperature and fresh it to clear it all out so the glow plugs come up to temperature and end up using it properly to kill off everything in the DPF and your EGR valve the next one that fails is the DPF pressure sensor as many of you guys know the DPFs have a pressure sensor on them so when they get full of pressure they will just throw an engine light on or won't let you start the car or will start cutting out or start bogging that is very very normal as I said the DPFs get clogged from doing too much short chips so it will trigger the sensor and if it triggers the sensor you will have to reset it and go and drive that car you have to force it into a regener generation cycle to be able to clear the DPF a lot of people I can tell you right now how many diesels I've had come to me and most of the time I can see on the system they've never had a regeneration on the DPF and I say to her are you even using this car to go they're like I hardly use it they use like three times a week they don't even do the mileage need for it hence why it doesn't do a generation on the DPF on the EGR so I have to force it with the scan tool to do a DPF regeneration to clear all the crap out and that is not a nice experience to do especially in my Because as many of you guys don't know a DPF regeneration when you trigger on a scan tool will rev the car up to get it up to temperature and to force the glow plugs to activate to start clearing the crap out and you just see a load of black smoke coming out of the exhaust it is not a nice atmosphere as well and neither is it a nice smell it's not something you want to do and garages will charge you a fortune for it cuz they don't like doing it either they just going to plug up a scanner it takes 5 minutes it doesn't it can take up to half hour 40 minutes to do a full a full DPF regeneration that's why I'm telling you guys make sure to get them up to temperature and make sure to run them because that will trigger the sensor and it's not the sensor many people go replacing it is not your DPF sensor the sensor is letting you know there's a problem with the DPF and the problem is that it's too built up in there it needs to be cleaned out now a lot of people as well always say about transmission issues rough shifting slipping gears now you got to remember these are the ZF 8-speed gearboxes on these B-57 engines if you are having any of them issues most of these B-57s now on what 70 80,000 miles and let's be honest anyone with a 3 liter diesel is not potting around local they are giving it a threshing they want to think they're in some kind of M car which they are not but unfortunately majority of people that own a B-57 seem to think that they are so they fresh the life out of the gearbox what ends up happening with that is you produce a load of more engine heat a lot more heat on the gearbox a lot more strain which then means your fluid breaks down which no longer protects the gearbox properly the internals most people do not change the fluid and filter on the transmission cuz they're scared to do it garages won't do it either my advice is make sure to get that fluid and filter changed that if you don't do that that is what's going to cause rough shifting and also slipping clutches you do not want that on your 8-speed transmission trust me on that okay i'm telling you right now if you have any of that get your fluid and filter changed because I know many of you are experiencing that on your B57 engine and diesels are notorious for it why because people fresh them from cold before the gearbox is even up to temperature before the engine's even up to temperature and they're fresh them before the oil's even lubricating anything inside the gearbox any of the moving parts and that is why they end up with rough shifting and clutch packs going out and the mechatronics failing as well because of people doing that because they're just hitting them and as many of you guys know on diesels between first and second there's like a delay between shifting when the gearbox are cold that's perfectly normal okay you need to let them come up to temperature drive them slowly keep the revs under 3,000 3,000 until it warms up do not frustrate but many people won't understand that it's like I'm speaking another language that's what you have to do if you don't want to do that don't own a diesel do not own a diesel i've own many diesels and I have never never ever ever had a problem with the gearboxes i even had the old X5 that people say is junk goes wrong with the gearbox i did thousands of thousands of miles in that never once had an issue with the gearbox not once and I didn't need to change the fluid because it was so low mileage but even when it got to the mileage I changed it and it was still flawless but you know what that was in someone else's hands the gearbox would already be slipping like most of them do but unfortunately it's all about how you treat the car if you know how engines work and how oil works you put two and two together and it should be basic knowledge but unfortunately there is people out there that do not understand do and I don't know how else to tell people i try and tell people this all the time do not fresh your car when it's cold if you don't know when cold and when it's hot put your heaters on inside the car when they are blowing hot air it means the coolant is hot around the engine and circulating around the engine which means the oil is at temperature then do what you want do not do it before that it's very very simple the next one on the B-57 which is very very common as well is the fuel filter clogging this is known on all diesels but the B-57 is even more sensitive because of all the electronics because of everything in place a lot of people like to try and run them down to reserves or run the crappiest diesel you can And this is why they end up with it jerking engine lights on not running properly going into limp mode damaging the highpress fuel pump from people running crappy fuel because even though the high pressure fuel pump was flawed by BMW there is people still on the original ones that are now on 70 80k on theirs with no issues they are making it to 80k while some people are failing them at 50k that's because these people seem to think they can run on the reserves you cannot run a diesel onto the reserves the fuel filter will clog up because it runs all the crap from the tank that sits at the bottom and also then you got the people that run the cheapest of diesel into it or they'll run red diesel or green diesel if they can get a hold of it and run it as cheap as possible i don't understand I still don't understand people's mentality to buy a 3 liter engine buy any diesel engine which is economical already and then try and find the cheapest diesel you can to run that car it will never ever make sense to me them people shouldn't own a BMW and if you are watching this you shouldn't be owning it it's a fact cuz if you have to go to the cheapest way to run that car you don't deserve that car it's a fact sell it to someone who does it's very very simple but unfortunately these people think they have the money but they can't have that much money cuz they're going for a diesel they're not buying exactly an expensive M car or a Porsche or a Lambo they're buying a diesel okay and they want to run it as cheap as possible make it make sense cuz it doesn't to me but they are the problem for them cars they people that buy them are the problem the car isn't the problem they are the problem and until people start to realize that then we will soon find out that BMW is reliable and it's not unreliable it's only unreliable in the wrong hands irresponsible hands but unfortunately this is the way it's always going to go hence why so many people are getting away from the brand it's not because they're unreliable it's because of what it's attracting the people it's attracting and that's a fact speak to anybody they'll tell you that's why a lot of them go to Mercedes or they're going more expensive which people can't afford to get away from the brand that people are abusing neglecting and giving the people that actually do look after them and do everything with them like me a bad name because we're not there to build the name up for people to tarnish it who ain't got a clue what they're actually doing or to how to look after their cars when there is enough information out there showing you how to look after your car you don't follow it you do as you please so another issue on them is sensors the oxygen sensors can fail on the B-57 along with the math sensors now many of you guys would have already experienced this and that can throw your car sideways the math sensor is responsible for the air mixture and it will make it run too lean or too rich and then your oxygen sensors will do the same which ends up leading to your miles per gallon being robbed poor fuel economy poor idling poor running not enough power check engine lights coming on you name it you got it they are known for the sensors going out and the oxygen sensors end up clogging up thanks to the DPF clogging up because they get suited up so badly they can't tell the difference between a lean or a rich mixture anymore and that's why they end up clogging up and they are not cheap to replace the same with a mass sensor a lot of these faults can be solved if people use the diesels the way they are intended to be used but as you can't teach people common sense so therefore that's why I'm putting it out there to you guys right now if you do have any issues of them it's going to be your oxygen sensors or your math sensors so make sure to check your math sensor as well and your oxygen sensors because they're all linked along with a DPF sensor there's a lot of sensors underneath the bonnet you need to know which one's what because if you got your lights on this is why you need to have a scan tool to be able to diagnose it and fix it most of you won't probably fix it you'll take it to a garage and even if you do it's going to be them faults it's very very common on them and you guys have probably already experienced it and solved it already so that brings me to my next one and the last one which is the recall on the BMW B-57 engine so if you've got a B-57 engine in your BMW you will be probably aware of the recall from the fire risk this is the reason why the police in the UK stopped using the BMWs with that engine purely because of the coolant pump connector and the engine ma software management which was causing the cars to go up in flames now BMW have got a recall out for that if many of you guys don't know about it where they retrified the issue where the coolant pump bearing in mind it's electronic wasn't kicking in which was causing the engines to actually overheat and then when they were overheating was causing them to burst into flames from the oil um causing the fire in the first place so if you haven't had that done you can literally go and get that done for free you'll see it above here where they've got the recoil out and you can go and get it done for free bmw do it for free for you you can check everywhere um your local government websites to see if your recall is outstanding in the UK you can go on the MOT history and it tell if the recall is outstanding your B57 engine make sure to get it done cuz if you haven't your car is at risk of catching fire many people ain't aware of that but yes here the police all use BMWs and they stopped using them after that happened to them quite a few times and obviously it only happens when you're using them in extreme conditions like basically revving the nuts out of them like the police do and that's when they go into flames when the coolant pump cannot cool them down effectively and quickly enough for what the engine needs for the way it's being driven and that's why they ended up going up in flames great if they're in a chase ain't it and they end up with their engine seizing right in the middle of it they'd be laughed at that's why the police end up cutting ties with BMW completely for that happening and if you guys haven't had that recall done on your B57 go and get it done it's all free bmw don't charge you they'll update all the software and make the coolant pump run and come on when it's needed but like I say it did affect a lot of them and that's the main recall on the B-57 engine is just the coolant pump and they'll update the software and program it to make it work effectively but that's all there is to the B-57 engine on the BMW now if you are considering getting one I wouldn't say to shy away from it because it's a solid and reliable engine unlike all the other 2 liters three-cylinder ones with a timing chain braking B57 don't suffer with the timing chain problem again why is that cuz it's a six-cylinder engine bmw don't have problems with six-cylinder engines they have problems with 2 L and their smaller engines with a 1.5 unfortunately BMW are very good at building six-cylinder engines yes they have their faults but once all them faults are rectified they are solid and reliable cars just like the M57 the old M52 M54 BMW never have problems with their six-cylinder engines it's usually their V8s and their 2 liters i don't know what they do there they can never balance it and get them right and I know BMW hate themselves for having to do 2 liter engines and if they could pull away they would but I hope this video is going to clear up a lot of this common problems on the B57 engine and I hope it will clear up a lot of the issues regarding the B57 engine for you guys who are looking to buy one or have one thank you very much for watching guys it's BMW Dr dean here and goodbye
