T-Cross Oil & Engine Warning Lights Need Urgent Check

Recently encountered similar warning lights on a Golf TSI. Car diagnostics revealed issues with both the oil temperature sensor and its wiring harness. The oil pressure warning combined with check engine light often points to sensor malfunction rather than actual oil pressure problems. The repair involved testing the automotive sensor connections first, since wiring issues are common failure points. In my case, corrosion had damaged the connector pins between the engine temperature sensor and the ECU. The mechanic found this after performing resistance testing on the circuit. The fix required replacing both the temperature sensor unit and repairing the damaged wiring harness. While not a major mechanical issue, these sensor problems require prompt attention since they affect the ECUs ability to properly manage engine operation. Before visiting a shop, recommend: Checking oil level manually, Recording when warnings appear (cold start vs running), Noting any rough running or performance changes, Getting error codes read at an auto parts store Though sensor issues are often straightforward repairs, ignoring oil pressure warnings can risk engine damage. Best to have a professional diagnose whether its truly a sensor problem or an actual oil pressure concern.

Thanks for sharing that experience with the Golf sensor issues. Your situation sounds quite similar to what I faced with my T-Cross last winter. Did the car diagnostics pick up any additional error codes after the repair? Mine showed a temp sensor fault initially, but clearing the codes revealed an oil gauge issue too. After fixing the wiring and replacing the faulty car sensor, my warning lights have stayed off. Would be interesting to know what you paid for the full repair job, prices seem to vary quite a bit for sensor-related work. Has everything been running smoothly since the fix?

Had the repair done last week and happy to report everything is working perfectly now. The car diagnostics confirmed it was indeed the engine temperature sensor causing the warnings. The mechanic found and fixed a bad cable connection that was disrupting the signal between the automotive sensor and the ECU. Total cost came to 95€, which covered the wiring repair and diagnostic work. Pretty reasonable considering some shops quoted much higher prices for a complete sensor replacement. After clearing the error codes, no additional faults have appeared. The oil gauge and all other readings are now showing normal values. The repair solved both warning lights, and the engine temperature readings are stable and accurate. The mechanic mentioned these sensor issues are fairly common on our engine type, often due to wear on the wiring connections rather than the sensor itself being faulty. Regular car diagnostics can catch these problems early before they cause any serious issues.

I finally went to my trusted mechanic last Thursday to sort out those warning lights. Turns out our initial suspicions about the sensor problems were spot on. The car diagnostics revealed the oil sensor was actually fine, but there was significant corrosion in the wiring harness. The mechanic showed me where moisture had gotten into the connections, causing intermittent false readings from the automotive sensor. They cleaned up the corroded pins and replaced a small section of the wiring harness. Total bill came to 120€, which included a thorough diagnostic check of the entire sensor system. Interestingly, while they had it hooked up to the diagnostic computer, they found and fixed a small issue with the engine temperature sensor too. Since the repair, all warning lights have stayed off and the oil gauge readings are rock steady. Really glad I got it sorted, feels good knowing the car is running properly again and all sensors are giving accurate readings.
