just a recommendation- most people do not have every trouble code memorized, and the grand majority of people will not take time out of their day to google all 7 codes to then be able to help you. If you could add what those codes are to your post, you will have a high probability of others helping you

To be very honest i dnt even know what these codes are.
The dealer suggested to get a new DME. I dont believe this. Maybe i am wrong.
I request all the members here to plz help me.

I took the car to the dealer. He used ISTA to diagnose. He said to put a new DME.
ISTA showed the following codes
1F0538
21A110
21A512
220507
220560
235410
D35A78

Are these codes related to DME failure or something?

How old is the battery? I've seen multiple instances where a dying battery shows multiple codes for random errors. I could be wrong, but if it was my car and the original battery, it try replacing that and registering it through ISTA first.

Ok going to check this

Can anyone help me with this problem.

My wgdc stays around 100 and i cant acieve target boost. Can somone please guide. No boost leaks. Wastegate calibration is also ok

Stop running logs until your engine oil is up to temp. That entire log, the oil temp never went above 200. Speculation, but the engine might be refusing full boost since it sees the oil temp as being too low and wants to protect itself. Just pure speculation there, but I'd run logs AFTER the engine is up to temp.

this is certainly true good sir! I cannot say where the threshold is for the OP's EWG. But PWG N55s- the DME limits boost when oil temp is below 140*F (60*C). I'd assume the same or similar for EWG (some BMW engines do this limit up to 160*F). I think he's outside of that, since the WGDC is at 100% early on (so the DME is sending the signal to make the target boost). But you do have a good point! Most don't know of this DME safety feature.


MANNERISM- boost never even comes close to target boost. WGDC is maxed out so the DME is trying to achieve it but can't. Im assuming no traction issues as this is in 3rd gear and you had no throttle closure. HPFP is plenty happy. Ignition timing is nice and even through all 6 cylinders.

All signs to me post to a boost leak sir! I suggest you smoke test it. An UNLIKELY options would be a faulty turbo. Certainly possible, but not unheard of either. If you smoke test and do not find any leaks... then my eyes would go to the turbo/ WG flap itself maybe excess play inside the housing

I am taking the car for a smoke test on the weekend. Hoping for the best
Thank you for your kind words sir.
I have a question.
I am using the oem inlet. Can this be the cause of this?
I,ll be grateful if you could clear my confusion.

negative sir, as the turbo inlet is on the suction side of the turbo, not the pressurized side. Boost leaks are on the pressurized side

Didnt find anything with air compression 25psi.
Lets wait for the smoke test. Will keep you updated.
Any other way to check the boost leak? The workshop having the smoke tester is too far.
Maybe you could advice something or some video link to help me out.

Here is a log with correct oil temp.

Oil temp is 183 when you hit boost for the log. What are you doing haha

That said, you can make your own smoke tester with a bike pump, a mason jar, an old sock, a cheap soldering iron, and some baby oil.

The oil temp is not fine yet?

Yeah i am arranging/making the smoke detector.
Hoping for the best

No boost leak detected from smoke test.
What to check next.

Well that's not good. If it were my car, my next step would be to inspect the wastegate actuator. I'd unhook the EWG and make sure that flap on the turbo is free of obstructions and can seal properly against the housing when in the closed position. I would also pull the turbo inlet pipe so I can inspect the impeller wheel. If that's damaged it will spin but won't compress as well as an undamaged unit (this can be hard to see but I do it by removing the inlet pipe, putting my phone in video record with the flash on then watch your video... or shine a light from the front into the impeller and use a mirror).

additionally! just an FYI- BMW's diag program ISTA+ has a test plan for the EWG itself. It's like a default position reset, moves it through the range of operation. You can have the test going and watch the WG arm move so you can confirm operation this way as well. This would assist to rule out the WG or the turbo

Can we do it on our own computer or the dealer only has it?
Where can i download it ?

Hello everyone

Why does my todays log look different than before or is it just me?
700NM torque 😶

https://www.bootmod3.net/log?id=6381...90c6e22f6d46a3


Can a restricted inlet cause this boost target issue?

[Zinia]

All test performed. Whats next?
