2002 Audi A4 3.0 Quattro.

The car's been acting weird, everytime I accelerate the car vibrates like no other. It's as ifI'm driivng super fast on a non-paved road. This occurs at 50mph and up acceleration. What could be causing this to happen??

I've been using 91Octane ever since the car was purchased.

 

does it also occur while braking? does it occcur when you are just cruising at say 80?

 

take it to the tire shop for free inspection, most likely tire balancing or alignment.

 

I have been noticing that lately on my 03 1.8T. Particularly on the steering wheel. Could be the balancing or alignment. I am yet to take it to shop for inspection. Do update if you find something.

 

if it was the balancing problem, shouldnt it occur when im not gassing it?

it only shakes if im pressing the gas pedal.
