Vibration when I accelerate in my 2003 Audi A4 1.8T
When I accelerate in my 2003 Audi A4 1.8T I can feel a vibration on the pedal that I had never felt before. When I get it up to 55mph the vibration is prominent and I can hear a humming sound from the engine. This happened after my min oil light came on and the oil has now been changed.

Does it feel like its coming from the front or a certain side in the front and can you feel it in the steering wheel or brake pedal.Is it only at certain speeds accelerating,braking,decelerating or is it constant.
this car has a fuzzy logic gearbox.if you drive using the first 1/3 of the pedal your gear changes will be smoother and fuel consumption will improve BUT the car will feel limolike to drive.the second 1/3 of travel will accelerate/change higher up the rev range and use more fuel.and you guessed it the last third is for idiots like me that want to feel the power....also always use the highest octane fuel you can get(minimum 95ron) ecm knows good stuff...and changes knock/timing accordingly.lastly,try a dose of redexe(or a lot) to clean out fuel system/injectors works wonders....
check the drive shaft between the intermediate transmission and the front transmission for miss alignement and defectivness of the telescopics system of this shaft. we had about the same problem on our 1996 same model...
I would venture to say your exhaust is hitting your frame, or, you may need new motor mounts. The exhaust is what I would lean toward. If you can imagine your exhaust sitting under your vehicle, and the fact that the vehicle has a little age, the motor mounts probably give a little, causing the motor to move slightly on acceleration and deceleration, thus your exhaust is going to move, and may be vibrating on whatever its touching. Good luck.
Where do you feel the vibration? if you feel it where you sit it is coming from back which is usually rear brakes. If you feel the vibration in your feet and hands it is coming from the front which could be your ABS or front brakes.
the u joints in the drive shaft. (CV joints on front wheel drive) more strss on the joints when accelerating so they cause the vibration. no stress/load smooth run. Replace the joints and you'll feel a big difference.
