VW Up Multiple Electrical Failures Points to Switch Issue

As someone with some experience working on VWs, I had a very similar situation with my 2014 VW Polo. The electrical faults showing up simultaneously pointed to a connection issue, just like what youre describing. The gear selector not displaying and starting problems often trace back to a faulty switch or loose connections. In my case, the workshop found that the clutch switch wiring harness had deteriorated, causing intermittent electrical faults across multiple systems. The repair involved replacing the damaged wiring and connections, which cost me 95€ including diagnostic time. Since fixing the connection issues, all electrical problems disappeared and the car starting has been reliable. Before suggesting more specific solutions, could you share: Does the engine crank when trying to start? Are there any specific error codes stored? Have you noticed any correlation between wet weather and these issues? Is your check engine light on? These details would help determine if youre dealing with the same root cause I experienced.

Latest service was 2 months ago at 58500km. The engine does crank but wont start. The scan showed P0704 and P0833 error codes for clutch circuit malfunction. No correlation with weather noticed so far, and yes the check engine light stays on. The safety switch symptoms you described match exactly what Im seeing. Getting multiple electrical faults and car stalling issues at the same time made me suspect a central issue rather than multiple separate problems. Based on your repair experience, this 95€ cost seems reasonable if it fixes all these issues. Will have the wiring checked first before replacing any parts. Thanks for confirming my suspicion about the clutch switch being the likely culprit.

Thanks for providing those additional details about the error codes. Your symptoms match exactly what I experienced, the P0704 and P0833 codes are classic indicators of a clutch pedal switch malfunction, just like what happened with my Polo. The car stalling and electrical fault combo is a typical safety mechanism response when the clutch switch sends incorrect signals to the ECU. In my case, the faulty switch created a cascade of electrical issues affecting multiple systems. After seeing the same error codes you mentioned, I first had the wiring inspected which revealed corrosion at the connector pins. The mechanic cleaned the connections and replaced the damaged section of the wiring harness. Total repair time was about 2 hours. Since the repair, my car has been running perfectly with no error codes or electrical faults. The 95€ I mentioned earlier turned out to be a good investment considering it resolved all the issues, from the gear display to the starting problems. Based on your identical symptoms and error codes, I strongly suspect youll find the same root cause. Having the wiring checked first is definitely the smart approach before replacing any components.

Thank you for clarifying those codes. After seeing the shared repair experience and cost breakdown, Im now confident about the source of my electrical faults. The clutch pedal switch diagnosis makes perfect sense given how my car is behaving. The intermittent starting issues and multiple system failures pointed to a central electrical fault rather than separate problems. Having identical error codes P0704 and P0833 related to clutch circuit malfunction really confirms the diagnosis. The quoted 95€ repair cost seems very reasonable considering it covers both diagnostics and fixing the root cause. Starting with a wiring inspection should reveal if Im dealing with corroded connections like in the other case. Will book the car in next week to have the safety switch and associated wiring checked. Its reassuring to know this is a known issue with a straightforward fix rather than facing multiple separate electrical problems.
