Common Problems with the AU??

[Casper]

Based on some suggestions from Bucknaked, this thread is to share your experiances with problems that have occured with your AU.
Be them common (like the shock mounts on the IRS models) or not so common (a dead MAP sensor making the car run rich and lose power), share it all here

The problem, the solution, the cost.


This is not a "I have a problem, need advice" thread, it is purely for those that have had a problem, found the cause and got it sorted. These experiances may save us all a lot of time, headaches and money.
