Anyone with Turbo Wastegate faliure?

[mrgicm]

So a few weeks ago I was driving on the highway doing 120kmh and drivetrain error comes up, I stopped truned off the car and back on and it came up immeadetley,

So I went home to check with ISTA and it shows Electric Wastegate short circuit and after deleting it it just came back.

I have BM3 Stg2 on my car for last 6 months and full Akrapovic with downpipes.

I went to the dealer and after 10 days the diagnose was to replace the turbo as the error was on the electric part of the wastegate which is a part of the Turbo.
They replaced ths Turbo and all is fine now now my question is has anyone had this problem and I dont know what could be the cause of this I am affraid of this happening to the other turbo as this one was not changed.

Thanks,

You can buy the WG separate. Part number 11657850453

However, we haven't heard of any failing. It's uncommon.

[mrgicm]

My dealer said it was not available as separate. I think he ment the electronic part of the wastegate as thats where the error was shown.
ISTA under explanation showed short circuit in the wastegate.

Thanks for your answer.

im dealing with it now...

edit:

codes thrown were 120408 (charge pressure cntrl), 123511 (electric wastegate, wastegate valve sluggish)


edit edit:

my wastegate valve gets sluggish after thai food

No issues with the tune and warranty?

It is not a common occurrence but it's not rare either. A lot of dealerships keep the necessary parts on hand because the N55 has a similar issue.

My car is currently getting flashed and I bought a jb4 for a back end and it was used got it installed and the settings were all fucked up so it keeps the wastegate in turbo 2 open on cold start which isn't supposed to happen.

This is the code I'm getting "An electric wastegate fault for stop position limits"

Not sure if that's the same but my car is currently at dealer getting warranted!

[mrgicm]

I flashed back to stock, they noticed the tune was on my car, red flagged my car. I had to pay for it my self. But my warranty has expired 2 months ago.

I had these 3 pop on on mine recently. Been running BM3 since November and am kinda worried as I sent them this and they had no idea what it was or meant. Any insight in on this would be greatly appreciated.

i should note mine is dinan stage 3. dealer and dinan spoke and everything is under warranty. no red flag.

Like Justin said, it's not a common issue for the S55 but relatively common on the N54/N55/N20 and most modern BMW engines utilizing forced induction. Like the OP had mentioned, you can technically change out the EWG on the exhaust manifolds however due to the physical adjustment factor BMW recommends to replace them as a whole(pair).

[mrgicm]

I got only one replaced... they said the other was fine...

A question, when you are driving with dsc on or in mdm and it comes on (stops the throttle) does the excess use the wastegate?

Or to simplify, if frequent driving under dsc control and interfirance is the wg/wg control being used more often?

Mine failed 3 miles from the dealership the day I picked it from delivery.....

Any idea how they noticed your tune after you flashed back to the stock map ? The BM3 suppresses the tamper code so curious as to how that happened.

[mrgicm]

I dont know, the stock map with tamper code off was loaded... I guess if it were a normal service they wouldnt but im sure if they 'dig' over the ecu they could.
I think bmw Germany had a session wih the car.

Its the risk we take when tuning the car.

This statement is completely false and it's disappointing that most tuning companies will pass off inaccurate statements stating that their tunes are "undetectable" or "untraceable" because it's far from the truth. Without starting a fire, I can honestly say that no tune is untraceable and it goes back to the age old saying, if you play with fire you will get burned or quite simply mod at your own risk...

It's not completely false. They do suppress the tamper code. The FASTA data will show it was tuned though if BMW decides to look there.

Hmm - not sure if you've had the chance to run the codes on a BM3 vehicle or not, but I can safely say that when I reflash back to the stock map, the tamper code is not present....which in essence makes my statement pretty accurate.

Now, whether or not BMW conducts other checks to determine if the car has been tuned is a different story. I'm sure there are but the tamper code method of verification is taken care off on the BM3 end.

People still like to argue this which I find funny. There is no way to utterly remove everything and I'm positive if BMW wants to find out if you have flash/tuned your car, they will definitely find out.

Whatever people do to make them sleep better at night.

[hdubf80]

If these codes haven't popped up again after he first time should I still be worried about the wastegates?

That's precisely it... I'll just leave my statement as a public service announcement and leave it at that.

Hey to everyone here!

Had 2 days ago the same problem.

Malfunction number 123601 Wastegate. Just let me know, did you noticed something strange (noises,missfires,response etc.) before it happend?

And also, thought it would be easier to replace the whole turbo instead of trying to troubleshoot it step by step, worth it?

Currently 75k miles. BM3 st2 93.
