I picked up A4 1.8T CVT yesterday. It is very good upto now excetp following vibration.
My friend told me that he felt some uncomportable vibration from the bottom under his feet after riding on the right back seat. I checked the bottom of the car I saw some black steel box is located. It is only on the right side of back seat. I believe that vibration is from there. Is it the oil pump?
Does anybody know what it is or experience that kind of vibration?
