Having problems with your 2006 Audi A4 ?

2000 audi a4 low erratic humming noise

\015 My 2000 audi a4 is making a erratic humming noise when in park and drive. It started making this noise after I had driven my car in low gear on a windy mountain road. When the car is in park i press the gas and as the car is winding up it makes the erratic noise, when I let go of the gas and it comes back down to idle it sound like it wants to back fire. I have checked all the coil packs and they are working fine. Is this a transmission problem?\015 Posted / edited by AnonymousUser on : 19-08-2019
