Wastegate needs to be replaced.

MonacoTT · 01-11-2008, 03:53 PM

Bump to see if this is a common problem.

Oh yeah, I also had my boost pressure sensor go out 3 months after the car was delivered (with 5k miles).

This turbo system is starting to concern me.

mattnagano · 01-11-2008, 06:48 PM

It's probably fine, you're probably just thinking you hear it now that you've read the thread. Just how peoples heads work, they'll find what they're looking for whether its there or not.

Did you really ever tune a turbo car? Or was that boost controller you said you used that almost blew your motor the extent of your tuning?

Cool Pic, thanks

RiXst3r · 01-11-2008, 09:22 PM

HOLY CRAP... my car makes this exact same noise... sounds like a metallic buzzing on decelleration.. I thought it was a heat sheild/exhaust thing too! You can actually here it better on the passanger side of the car, but it sounds like its under the engine

It was really bad a few months ago, and now it went away mostly, but it is still there

I was about to take my car in, and almost forgot to mention this! Thanks for the thread

mattnagano · 01-12-2008, 01:48 AM

o-cha thats wat i thought at first but its pretty loud i can hear it anytime the windows are down...and i had my friend rev the car while i was outside its pretty damn loud...

Bump for more information on this issue.

Post if you are experiencing the symptoms.

Same problem once more.It seems to be more and more cars with problem in the wastegates.What happens if this comes after warranty.The turbos cost a lot of money.

My car goes in tomorrow to have both actuators replaced. was in last week and they diagnosed the problem. Its been making the noise for about 4 months and i thought it was a heatshield. car has vihnu exhaust and v2.
problem was there before i got both i think!!

Serjames · 02-05-2008, 05:22 PM

anyone got the bulletin or a link to it ?

thealbert · 02-06-2008, 08:04 AM

Oh my! Sounds like another problem just like the fuel pump! I remember reading a TSB about this problem, apparently it said that BMW Tech Engineers are still trying to figure out whats causing the problem. Looks like they narrowed it down to the wastegates already. Although I'm sure they're asking to replace your whole turbo so they can figure out whats causing the problem. Were you still able to drive the car even with the ticking? No fault codes were thrown on your computer right?

thealbert · 02-06-2008, 08:38 AM

does anyone have a video of the ticking sound?

BlueLion · 02-06-2008, 08:43 AM

not the ticking thing again

a ticking time bomb is not a problem until it stops ticking

It turns from a ticking into more of a buzzing at higher RPMs because of the high frequency.

I would record a sound file, but my car is stuck at the dealer.

I'll keep you guys posted.

interested to hear the sound file. thanks!

john335 · 02-07-2008, 06:41 PM

sorry guys no sound file, would be hard to hear i reckon with a recording.
Got the car back today with 2 new turbo's and no more ticking!! yipeeeeeeeee

car is a good bit faster now too, prob because no boost leaking

Also think this may have been the cause of my limp modes with v2

MonacoTT · 02-11-2008, 01:43 AM

On my car the turbo that went out was the rear turbo (cylinders 4, 5, 6).

I remember reading somewhere that bypassing the boost solenoid (as is required with several of the piggyback setups) puts more stress on the rear turbo.

Seems like this problem is common in cars where people are doing this (not sure if it's just common in general - I guess it could be).

I did it briefly because I had a JBS2 in. I took it out before the service appt. to investigate the ticking... never put it back in.

I'de like to hear more from those who know about the intricacies of bypassing the boost solenoids and long term effects.

I think I'll leave my JBS2 out until I've done enough research on the subject.

How did you get your dealer to replace the turbos. I have the same problem and the a$$holes told me to wait until they find a way to fix it. The tickling sound is getting worse and more sounds are starting to come from the engine.

Are you sure that you have the same ticking (coming from the turbo wastegate).

If so I would demand having it replaced citing that this issue can have effects on boost pressure which is a serious concern to you.

You can also site the fact that you know several other people who had the issue and had their turbos replaced due to the issue.

If they continue to be stubborn, try a different dealer or open up a case with BMWNA.
