Question 1

Why does my DSG gearbox warning light come on but clear when I restart the car?

Accepted Answer

This is the classic early symptom of a failing DSG DQ381 mechatronic unit. The mechatronic contains solenoid valves and electronics that manage gear selection. When it begins to fail, it throws fault codes P173500 or P173600 and the gearbox ECU flags the warning light. A restart temporarily resets the flag — but the underlying fault remains. Left untreated, it progresses to limp-home mode or complete loss of drive.

Question 2

Accepted Answer

At MnF Motors we provide transparent, itemised quotes after a full diagnostic session. Mechatronic repair or remanufacture is typically significantly cheaper than main dealer prices. Call us on 020 8803 1231 for a no-obligation estimate specific to your vehicle and fault codes.

Question 3

Is it safe to keep driving with a DSG gearbox warning light that clears on restart?

Accepted Answer

Not for long. While the car may seem fine after restarting, the fault is progressive. Each drive cycle stresses the failing mechatronic further. You risk being stranded in limp-home mode — or losing drive entirely. We strongly recommend booking a diagnostic as soon as the warning light appears for the first time.
