Hello, I need help with my car, it's an A5 3.0 tdi quattro '08 with 80K milles
I've remapped it with aprox. 300hp and 700nm (515fl).
My problem is that accelerating at low revs (between 2000-3000revs) in long gears (4th, 5th & 6th) there is an intense vibration/tremble around the rear diff. I'm not sure the vibration is in the rear diff or in the drive shaft.
Over 3000revs there is no problem at all, also in short gears there is not any vibration.
I'm pretty shure it's due to the high torque. But I have limited the remap to 600n/m and the vibration remains.
I have a friend with exactly the same car and remap 60k milles, and it has exactly the same vibration as me. So the problem it that the rear diff/drive shaft/ shaft bearing of this car can not allow this torque in low revs without trembling.
I like so much torque between 2k-3k revs, had anybody similar problems?
I would like to know any mods I could do to allow the rear transmission to hold high torque
thanks you very much
