E61 MT - 535XI w/ N54
Hey guys,

E61 N54, MHD stage 1, 91 octane. I keep getting throttle closures under full throttle. I can't get a good log because the closures but here is a short one:

http://datazap.me/u/potato/e61-n54?log=0&data=3-5-10-23-26-30&zoom=16-42

Any ideas?

Newer plugs, carbon cleaning, vacuum lines, injectors, coils. I do get a 30FF on occasion. I have pretty noticeable wastegate rattle. I turned off the MHD wastegate rattle fix and it did not seem to help the throttle closures.

I haven't done any maintenance on them.... I do have a bit of vibration under hard acceleration that my mechanic was not able to completely eliminate (we rebuilt the driveshaft & replaced the front axles). He thought it might be flywheel related but wasn't sure. Perhaps these are related...

With everything off.. you should only get limited power if it thinks that it would ultimately save the DSC or 4x4 system. Kind of like an emergency kill switch you could say.. but, drive around normally but, cut the DSC off (DTC one click) just to see if anything occurs. You don't need to consistently keep it off but, just to see if any other signs occur.

Also, any clunking or anything when slowing down a lot?

It does seem like something is intervening "as a last resort". I will try driving around after pressing the DTC button once to see if I notice anything.

I don't recall any clunking.
