Vibrating noise coming from engine
Hi, appologies for the possible repeated thread but i wanted to describe the symptoms exactly.
I've noticed during the last few days that as close as i can describe it, a vibrating whirring noise coming from the front of the car that sends small vibrations through the car. I had noticed it just after having the front tyres changed so took it back in and the guy checked the brakes and wheel balance and all checked out fine.
The problem seems to occur around 1.5k revs upto 2.5k, particularly noticable when in a high gear and decelerating through that rev range. Depressing the clutch and putting into neutral has no effect, the noise persists. However if the car is stationary and i rev the engine slowly to redline there is no abnormal noises at all. I might embaress myself here but could it be the flywheel bearing or something? The only other thing i could think of was a piece of plastic trim underneath might be flapping about like a twig in a gale at a certain speed (resonant frequency). To be honest though that is probably wishful thinking.
I'm going to have a look under the car tonight, see what i can see just any pointers would be greatly appreciated and have a merry christmas.
Oh btw it's a 1999 a3 1.6 sport, 182k miles but regularly serviced.
Just to update anyone who may have a similar problem. I notice the noise when i turn the steering (shift the cars weight) to the right. Took a mechanic for a drive and he instantly diagnosed it as wheel bearings. Around 100 quid all told to fix.
