Hello municipality I have been on my R8 V8 BJ 2007 a strange sympthom: If he has stood for 1 day and is really cold, I have a very high whistle/singing noise when driving, which also changes with the engine/gear speed, (similar and very good comparable to a flying drone) After about 30-60 seconds driving this initial noise has completely disappeared, and the R8 drives as always, without problems, without error messages in the KI ! As I said, so far he has always stood about 1 day.If I drive in between, this initial noise is not! Will however tomorrow, if he is cold again test, whether this also occurs at the level when giving gas, or only while driving, where I would then more honorably push it on the gearbox! Someone on his R8 already had something like that, or. has an idea? Would it horror to drive back to Audi and get rid of a lot of money for nothing (as at the last time) by hours. on resultsless searches for the causes etc. Greetings Rainer
