3730 Tiptronic

Problem
The stored pressure adaptation values are lost if the power supply to terminal 30 is interrupted. This can result in poor shifting quality and rough shift operations during the adaptation phase.

Remedy
Carry out a test drive and drive the vehicle with different loads and at different speeds so that all shift functions (manual and automatic programme) are executed at least once.
This readapts the shifting pressures of the system and thereby re-establishes smooth shifting.
