Please can you help, I have a 2016 Audi A5 with 61,500 miles. It developed a knocking noise and both drive sharts were replaced (now looking at MOT the nearside Front Outer Drive shaft joint constant velocity boot split was replaced September 25) Since the drive shafts were replaced the car has developed a vibration through the seats when put into gear. It has since had engine mounts replaced, brakes ?shoes and discs. It also had the transmission oil changed but unfortunately the guy didn't do the filters !! We still have the vibration which if you drive, it disappears ay 1500 RPM and drives well. I have had various people look at it, 50% say get rid!! A local garage that is known for gear boxes has suggested Dual mass fly wheel and said it "should" solve the problem costing aroung £3000, but should is my problem. any suggestions or ideas greatly appreciated. I am based near Great Yarmouth.
