whine/buzz - loss of power?
Hi all,
At moderate speeds of 15-30 city driving, there's a whining noise at 1500 rpm and up - perhaps more of a hum. I know there's twin turbo...but the sound is louder than before. Anyone have experience w/ that? The sound is definitely louder than before the recent work.
Also, when I'm on hwy going 60mph and I step on the gas, the kickdown that I used to feel that immediately thrusted me to 80mph is gone...feels like regular V12, not TT. Anyone have ideas on these symptoms, and are these 2 related?
Thx, and happy thanksgiving to all.
