Hi guys (long time lurker here),
My 45000km '06 2.0L TDI with Superchips map, has developed a new noise. Picture this: Car is in D, and short shifting to 4th at like 50kph. I squeeze the throttle enough that I'm accelerating hard, but the DSG hasn't kicked down. It sounds fine before the turbo reaches boost, but as soon as it has, you can hear a VERY disting friction sound coming from the turbo.
The noise is over the top of the regular turbo-spooling sound. It occurs only at full boost if that makes sense. So pulling away I do not hear it until i'm properly accelerating. It's much easier to hear in a higher gear then usual at lower revs. So 5th gear at 60kph, squeeze throttle and it's a bearing whine.
It does not sound like a leak, but I'm not entirely sure what a leak might sound like to be honest. It sounds very mechanical, very metal-on-metal. Possible bearing of some kind?
The car was JUST serviced (last week at the dealer for 45000km service) and nothing wrong was found besides wheel alignment and wipers lol.
Any ideas? If you have a video or soundbyte of something similar, or of a specific problem (so I can rule it out as sounding unlike that) then please post it
Thanks, Dom
