VW Touran Oil Sensor Warning Signals, Repair Guide

I had similar warning lights with my VW Golf 2015 TSI. The engine sensor readings were inconsistent, triggering oil pressure warnings despite proper oil levels. After car diagnostics, the problem was traced to a faulty connection between the oil sensor and the control module. The repair involved: Testing the engine temperature and oil sensor circuits, Replacing corroded wiring connectors, Clearing stored error codes, Verifying sensor communication This was not a severe mechanical issue, rather an electrical problem common in these engines. The car sensor system can trigger false warnings when connections degrade. The actual oil pressure and engine systems were working properly. Worth checking: Oil level and condition first, Connection points for corrosion, Recent engine temperature behavior, Stored error codes with a diagnostic tool Best to have a qualified shop inspect the sensor connections before replacing parts. The symptoms match classic signs of wiring issues rather than failed sensors or serious engine problems.

Thanks for sharing your experience. The same happened to my 2012 Touran last winter. After initial panic about major engine problems, it turned out the temp sensor and associated wiring were the culprits. The automotive sensor system was giving false readings because of a damaged connector. Can you remember how much you paid for the fix? Also curious if any other issues came up since the repair was done. My car had some related electrical gremlins a few months later that needed sorting with the car diagnostics system.

Had the repair done last month, the faulty engine oil temperature sensor issue got sorted quickly once diagnosed properly. Total bill came to 95€, which covered fixing the cable and plug connection that was causing the sensor malfunction. Since the repair, all engine sensor readings have been stable and accurate. The oil gauge and warning lights are working as they should, with no false alerts. The automotive sensor system is now communicating correctly with the control module. No additional electrical issues have surfaced in the weeks following the fix. The key was finding a shop that properly diagnosed the temperature sensor connection problem instead of jumping to replace the entire sensor unit. Their thorough testing of the engine sensor circuits saved both time and money. My recommendation would be to have any electrical gremlins checked promptly, these sensor connection issues can sometimes indicate other wiring that might need attention. But in my case, the initial repair has held up well with no further problems.

Thanks for the helpful responses. Just wanted to share how my situation got resolved. I took the car to a different mechanic who actually listened to the symptoms. They ran proper diagnostics and found the temp sensor wiring had deteriorated, causing incorrect readings. The repair was straightforward, they fixed the corroded connector and replaced one damaged wire section near the oil sensor. Total cost was 160€ including diagnostic time. Much better than the 400€ quote I got from the first shop who wanted to replace multiple sensors. The car has been running perfectly for 2 months now. No more warning lights or oil pressure alerts. The engine sensor readings are all normal. Really glad I got a second opinion instead of paying for unnecessary parts replacement. A lesson learned about finding a mechanic who takes time to properly diagnose electrical issues rather than just swapping parts. The automotive sensor system in these cars can be sensitive to wiring problems, but fixing the actual issue doesnt have to break the bank.
