An error with the start-stop system on your VW Tiguan when starting the vehicle usually points to one of the following issues:
-
Weak or aging battery – The start-stop system relies on a healthy main battery and sometimes a secondary one. Even if your Tiguan starts fine, if the battery voltage dips too low, the system will disable itself and show an error.
-
Faulty start-stop button or sensor – A problem with the brake pedal switch, clutch sensor (on manuals), or hood latch sensor can also prevent the system from activating.
-
Stored fault codes – If there's a fault in the engine, transmission, or electrical systems, the start-stop function will automatically disable until the issue is cleared.
Try scanning the car with a diagnostic tool (OBD2 scanner) to retrieve any fault codes. That’ll narrow down the culprit fast. The manual contains every DTC codes and troubleshooting charts too so you can solve this issue.
