Previous owner did the valve cover gasket. Not sure if they did the valvecentric re-learn or not. I did DISA valves, new vanos selenoids, cleaned vanos filters. All codes gone car idles a little funny only when AC is on. Yes I used chinese stuff just because It's my 1st BMW and I'm afraid to dump a ton of money not knowing if I made a mistake buying this car. I will replace them with oem once I'm confident. Car is a 06 330i with 220k miles.
hi ! many owners have relearned valvtronic with ingition , but very confused now as you said it need to be relearn with scanner, is there really a risk to relearn with ignition ? if you can do a video of relearning valvetronic with scanner it wouls be very helpful thks
Hey Dean. I have two strange problems with one 128i with N52 engine. When starting hot the car missfires and has bad idle for like 3-4 seconds and after that it runs like a dream. This is every hot start ever. The other is that there is a strange grinding noise coming from the engine compartment. It is definetly not the lifters, I have watched your video. I think it might be the oil filter. When I touch the gas pedal the noise dissapears right away. There are no codes in the DME, I scan with Ista. Thans for your videos !
Mate can you make a video about the E46 318i 2003 engine ? I am having rough idling , scanner showed camshaft sensor , exhaust, ambient temperature, thermal oil-level sensor . I ain't sure what the problem might be but please, if you know or make a video , I would really appreciate it . Note : we got really bad BMW mechanics in Lebanon, please save my ass brother
I have a 2010 Z4 that in sport or sport+, ac on high, hot summer day DIES randomly when you come to a stop. Starts back up like nothing was wrong. Normal mode no issues.
do you mean your z4 relearnedthe valvtronic just with ignition ? i also have a z4 but very confused if it can be done with ignition or diagnose tool absolutely
Hi please I got a 2008 bmw 528xi and I got the code p0171 and p0174. I got hot car died by it self and now car won’t start it cranks but not starting please I need help I changed the fuel pump and bodytrotlle
Hey Doc, I am throwing a P2096 code and had a rough idle. My mechanic changed both upstream 02 sensors, did a smoke test (no leaks) and there is still a rough idle, almost like the throttle is acting like im giving the car gas. Any ideas?
Sounds like you are running a bit rich, could be leaky injectors if there are no vacuum leaks, or it could be related to the MAP sensor on the intake manifold which influences long term and short term fuel trim
Thanks great information! Chinese parts are a sure way to ruin your engine!!! Amazon sells a lot of Chinese parts which have OEM parts manufacturers names on them! I had problems with an oil pressure sending censor. I replace it with a beck Arnley twice, come to find out it was made in Taiwan. So I had three times the work to R&R them, scared the wholly hell out of me on the highway cruising along 90 MPH. Though I had lost all oil pressure and blew out all my oil! There was actually nothing wrong with the my M54! Well I learned to check the country of manufacture on all my parts!!! I was lucky, never buy Chinese parts, Never!!!! Thanks again great info!
I bought cheapo vanos solenoids (no name) for my N52 at first because of codes, but still caused issues and threw vanos codes. Went with OE solenoids (4x price) as recommended by Dean and no codes since :> Parts look very similar but seem to perform very differently.
Hella (German brand) cam shaft sensors (made in China) has worked fine on my E46 though. Guess "no name" parts is no-no if expected quality is yes-yes ;)
there you go my friend and i'm glad you took my advise this is why people see me differently. and everyone can say what they want about me but the fact remains you CANNOT I MEAN CANNOT get away with cheap parts on this engine and people hate me because i tell them the truth. i'm not here to have your cars running like a bag of spanners just to keep you watching and watching to get more views until i decide to put out a video showing your problem LIKE MOST DO !!! i only tell the truth about these engines and what is required to get the most power best fuel economy and the best sounding and performing engine the way it come out the factory. MOST RU-vidR'S will make you use chinese parts just so they can benefit from the clicks and parts bought to fund there own pockets as many of you realise i'm not like that i don't like up all these parts to make you guys click. also alot of these guys on here will fit these cheap parts and then replace them with genuine after the video and not even record it and then say there car "is still running perfect" with the chinese part as there PAID to do them videos
Would any of these issues cause a missfire only when idling and fully warmed up? My car starts and runs fine initially and also runs fine under load but stutters at idle once warm. Above 1000rpm it is fine. Missfire is across all cylinders and has no obvious pattern to it like it does when a coil goes bad etc.
New turbo's new coils ,plugs ,vanos ,new battery not done the update 08 e61. Help me. I'm loyal to n54. Don't make me e60 m5 out. Cause I've got my eyes on one love ur channel God Speed
Hi mate can u help please I got a bmw 525i m sport 3 litre and its rough idle in cold start after driving it it goes away and the code I have is po175 system too rich bank 2 can u help please thx?
Hi there, I have a Mini with the B37 diesel engine, and something very weird is happening, so after a few hard accelerations the swirl flap will stuck at about -7% no matter what the desire value is, and the turbo will not work (and the acceleration will become very weak) until the car is restarted, what could this be? Thanks
Great vid as usual mate. Just one thing with the MAF - there IS an issue with these silver top motors (analogue MAF) where the plug can cause connection issues with the MAF itself. It presents itself as a 2d06 or something similar. I had the issue on my N52 (130i). Simply cleaning the MAF, it's terminals and the plug terminals with MAF cleaner and electrical contact cleaner worked for me, but some people need to replace the plug plastic and pins. Very cheap parts, but soldering required. Just thought I'd mention that!
I appreciate your knowledgeable advice...however...you forgot to mention CHANGE THE DIRTY OIL!.....Also, we have had a hit on income, and it is highly recommended [like u said] to make sure you can afford a BMW....I was an aircraft mechanic and BMW is killing me❤😂...but I have learned a new respect
My X5 throws misfire codes and the whole air intake is shaking..what you think on that? Also my 328i has no code but rough idle Nd makes a loud noise like it coming from where the exhaust manifold meets the exhaust pipe
BMW Doctor I have a problem I have a 2011 BMW 328i e-90 engine 52 3.0 L I'm getting a 2A7C DME cam shift verbally timing. How can fix the problem thank you.
I have a 2013, BMW 128 with only 30K miles. At idle it will randomly make what feels like a mis fire or "shudder" and I can see the tach briefly dip about 150 rpm then bounce back up to normal also, when accelerating in 3rd gear or higher If you open the throttle too much you will also get this shudder or mis fire feeling. If you mash the throttle to the floor it's better...you might get only one 'thunk" and then it runs perfect all the way up to red line. there is no CEL on the dash and scanning the car reveals no codes except for the "dirty air open and close recirculation on air cond" sensor. What the heck is wrong?
Hello. I bought a used BMW 523i N52 F10, 2.5. It came with a bad DME, so I went out and bought a DME which was programmed and fitted. I have a Drive train Malfunction and its showing a Misfire after DT. Would you recommend a Software update on the DME??
Hi Dean I know you don’t answer questions however my timing chain stretched on n53 engine could soilnoids do this ,the car only done 80000 miles did change the soilnoids to one ones after the chain was changed because I was getting codes just point out though didn’t have the car long now I’m wondering if someone had put cheap parts on the car as I thought timing chains were 100% on these engines .
hey I just owned a a BMW 525i but it was park for one year but start some times am from Jamaica but living in Saint Kittsand Nevis now can I get a number for you
Hey bro nice video! I have a problem at the moment with my bmw 135i m sport 13 plate The car was misfiring I brought new all 6 sparks and coils and again still misfiring! Iv done everything bro and I don’t know what to do I need help! Do you have a garage? Kind regards
great thorough video again doctor! I re and re my Valvetronic motor for VCG, didn't relearn the motor with scan tool. Car starts up and drives no problem, but have a little rough idle. Do you think this can be the reason from not have it relearned it's steps? Thanks in advanced
poocb code low air flo.replace coils and plugs,changed mass flo air sensor.running a little rough when on a cold start.do you know anything about this codes fix.thanks
Omg , now I get the answer from u bro, may God bless you and your family and I pray to God ,may God give good health and happy life to u and your family. Amin....
Great video bro, I have a 2004 120i e87(n46) I have rough idle, only seems to do it at 750rpm, seems fine to drive though. I have code p110d (throttle position sensor) does this mean I need to change the accelerator postition sensor/accelerator pedal? I can't find a throttle position sensor anywhere. Plugs and ignition coils have been replaced. Thanks man
would this apply for my 2015 435i gran coupe?? i replaced my valve cover gasket, spark plugs, and oil at the same time and i’m getting a cylinder 4 misfire code along with a rough idle when i turn it on
The ground strap yeah I can see how that's common we left off because I did it although I did not break the map sensor I took that off and put it back properly but yeah I didn't leave that ground strap off. But that's a lot of good information you know I rarely give you a thumbs-up and I rarely watch your videos all the way through you have a tremendous amount of information and you know what you're doing but I just don't understand why there's no need to be so rude I mean maybe you should do less RU-vid videos and more private videos and just do videos for people that are paying you I don't know I don't know if you have problems with some other place in your life or if that's just your nature but it definitely turns me off a lot of times I normally can't even get through half of your video but that's just me. Anyway hope you're having a good week no sense being down in the dumps you get more flies with honey then you do with vinegar have fun
thanks for letting me know ! this is the first time i have seen you comment also, and its good to know who is always disliking my videos then. but rude who am i rude to exactly ? i think your meaning because i'm very upfront and don't care what i say because i'm not here to give bulls**t and lies about these cars, i only ever speak the truth my friend i don't go about to upset people. but the truth only hurts them who most of my stuff relates too, but it can be changed in a few simple steps follow what i say or you will be one of them who i always mention about. and (INFACT) find me very rude and upsetting but i ain't going to ever sugarcoat my feelings as this is what has helped me get where i am today for not feeding people bulls**t like most of the you tubers on here.
@@BMWDoctor I don't do dislikes I mean like I said a lot of times I'll stop watching videos but mainly I come off like that because I have kids and I know that they watch everything on RU-vid that I do. But no I thought most English were like shmee150 LOL And by the way mine is an 07 530 that I spend a lot of the time doing up keep on because I use it for Uber under normal circumstances lately I have been staying at the house cuz it's not worth my time going out
no I dont even know who he is mate and I'm definitely not like that YES English have a bad reputation for the swearing that I know too well ! its what we are famous for but then alot of other Americans do like that way about the British only some don't like it, for instance most of my subs are around 18 to 23 years old I hardly have older people then that watching if I'm honest.
Doctor, what is the black box between the intake manifold and air intake box? Can't see that on my N52 with silver value cover built in Munich (E90 2006 325xi)
Hey Great Video! I have a rough idle problem with my E64 630i when cold. The engine code is N53 Would you have any ideas what could be causing this problem . Thanks
Vanos sylinoids def gotta be my issue thanks bro. Change high and low pressure fuel pump, water pup had it updated and then I noticed the ruff idle vibration. Gotta be the vanos sylinoids.
This is great! I pulled the manifold to replace the DISA valves and the map sensor wire was broken and the mechanic used wire nuts and electrical tape to fix the wire!
Hi m8 great video i have rough idle just first 15 sec from cold start car runs like dream just rough idle straight after start with a bit blue smoke. What should I look at it. Cheers
Good day sir, my bmw fl10 has this tendency of cutting out power when I come to a stop. It's performance is still okay but it cuts power when coming to a stop. Can you help please?
Thanks for the video. I have an E60 25i n52, it's cranking but it won't start. I had some cams errors, I replaced the 2 sensors, now the cams errors are gone but I have a p1024 valvetronic error.. the engine is still not starting. Don't know what to try.. Any ideas?
The valvetronic-sensor (it's NOT cheap) can be the problem and when you're already there, a new valvetronic-motor is always better. And try looking at the crankshaft-sensor, the ECU wants to know is the engine rotating.
People talk bad about these engines but I was working on my friends 5.7 hemi which he claims is supper strong and durable but the n52 is built 100% better than that thing
Any ideas for an intermittent vibration at 80mph? Not correlated to rpm, have had the tires road forced balanced and have new wheels. The vibration is very consistent, it phases in and out. ~3s of smooth driving and then ~5s of shaking increasing and then decaying. this cycle repeats while the car is cruising at 80mph.
Might be a broken reluctor ring on one of the drive shafts, which forces the TC to activate the brakes since it reads a speed difference between the rear wheels.
I really like your videos I’ve learned a lot my only problem is your music in the beginning if all possible have any other music without cursing or profanity. Thank you
yes only for the unfortunate who think they can treat it like your average car , thats the only people who say that when they realise this car doesn't take cheap parts. and its only junk in the USA but blame your factories for using all Chinese parts on your cars from the get go. as BMW in the UK is not the same as in the USA go ask anyone they will tell you the same how there cars don't ever suffer the amount of issues you lot do, which is a good thing
