VW Virtus Oil Warning Signals Point to Sensor Issues

I had a very similar oil monitoring system issue with my 2019 VW Polo, which shares many components with the Virtus. As someone with some hands-on experience maintaining my own vehicles, I first checked the basics, oil level and condition were perfect, just like in your case. The automotive oil warning signals were exactly as you described, unusual pressure warnings despite the engine running fine. After taking it to my regular workshop, they found a loose connection at the oil sensor plug. The cable connection had worked itself loose over time, causing intermittent oil signal errors. The fix involved cleaning the connector, securing it properly, and clearing the error codes. Total cost was 95€ including diagnostic time. Since the repair, the oil pressure warning has never returned. Before suggesting more specific solutions, could you share: Current mileage on your Virtus, Whether the warnings appear more frequently when the engine is cold or warm, If you notice any pattern with the warning (during acceleration, idle, etc.), The exact error code from your diagnostic scan This information would help determine if your issue matches what I experienced with the sensor connection problem.

Thanks for the insights about the connector issue. My car has 107074km on the clock and the warnings seem totally unusual, they occur regardless of engine temperature or driving conditions. The oil detection system warnings typically flash 2-3 times during a normal drive, but the engine performance stays completely normal. The recent car maintenance record shows all oil changes were done on schedule, with the latest service just 2 months ago. This actually sounds very similar to your experience with the loose connection. I noticed the automotive oil pressure warning becomes more frequent after driving on rough roads, which could support the theory of a connection issue rather than actual oil pressure problems. I will have the workshop check the sensor connections first before replacing any parts. The oil gauge and monitoring system might just need a proper inspection of the wiring and connectors.

Your connector issue description matches perfectly with what my repair shop found. Especially since you mention increased warnings after rough roads, it strongly points to the same faulty sensor connection I experienced. The car maintenance technician who fixed mine explained that oil sensor connectors can develop minor corrosion or loosen over time, particularly around the 100000km mark. This causes the oil gauge system to send inconsistent signals to the engine control unit. A thorough cleaning of the connector pins and proper reseating of the oil sensor plug resolved my issues completely. Just make sure the workshop does a full diagnostic reset after fixing the connection, in my case, some error codes remained stored until they cleared the system. If connector maintenance doesnt solve it, the oil sensor itself might need replacement, but start with the simpler fix. Most workshops charge about 1-2 hours labor for connector service and diagnostics, significantly less than a full sensor replacement. Looking at your mileage and symptoms, Im confident youre dealing with the same connector issue I had. The unusual nature of the warnings is a classic sign of connection problems rather than actual oil pressure concerns.

Your situation with the unusual warnings and increased frequency after rough roads matches my symptoms exactly. My Virtus has 107074km on the odometer, and like you mentioned, the warnings appear regardless of engine temperature or driving conditions. The oil detection system typically flashes warnings 2-3 times during a normal drive, but the engine continues running smoothly. All car maintenance records are up to date, with the latest oil service completed just 2 months ago. Your experience with the loose connector makes perfect sense, especially since my automotive oil pressure warning becomes more frequent after driving on bumpy roads. This really supports the theory of a faulty sensor connection rather than actual oil pressure problems. Based on your repair costs, having the workshop check the sensor connections first seems like the most logical approach before replacing any components. The oil gauge and monitoring system likely just needs a thorough inspection of the wiring and connectors. This should be a relatively straightforward fix compared to a full sensor replacement. I will schedule an appointment and specifically ask them to inspect the connector pins and wiring before considering more extensive repairs. Thanks for sharing your experience, it helped narrow down the likely cause of these frustrating warnings.
