6

Left or right front window does not close completely

Faulty normalization

Use the HHT (adaptation control module, normalization) to de-normalize the window and close the window manually using the window regulator (to block) and hold the power window switch down for > 1 s

7

Front power window frequently de-normalizes

Voltage supply, circuit 30door control module intermittent open-circuit

Hall-effect sensors

Coding in electronic ignition and starter switch (N73) incorrect

HHT: Adaptation control module, normalization
