Infotainment and electrical faults (MQB-A0)
cheap repairThe touchscreen system freezes, restarts on its own or does not respond. The stop-start can drop out as early as 15,000 km: the indicator stays lit and the engine does not stop. The parking sensors report a false obstacle, and the automatic light switch drops out. The driver's window stops because of a broken door wiring harness. The boot lock stops because washer fluid gets into the connector.
What to check
- Leave the infotainment running for the whole test drive and watch for freezing
- Check whether the stop-start works; if not, what reason it displays
- Try every window, especially the driver's one, all the way up and down
