Q1. Auto Trans needs a filter replacement due to abrupt changes from 1-2 and 2-3. Where's a reliable place that will do the job?

Q3. Left electric sliding door actuator broken. Where's a decent place to get one?

Q4. The computer module is only generating single fault reports. I talked to a dubber devotee who talked about his experience with a wiring problem in one of his T4's. He said, when shipped to Australia, dubs are sprayed with wax to minimise salt and shipping emissions from damaging the whole vehicle. When they arrive the wax is removed before sale. If the wax near wiring connectors are damaged then errors develop and remain until the damaged wiring is repaired. I discussed the error with Auto Union and said the diagnostic process to find the fault would take about 2 hours.

Q5. Exhaust manifold studs top left missing, bottom right persistently loosening, both inducing fuel mix irregularities.
