VW Taos Oil Pressure Sensor Issues Need Troubleshooting

Faced a similar oil detection issue on my 2020 VW Tiguan last month. The persistent oil pressure warnings appeared even though the engine oil level was correct after multiple checks. The root cause turned out to be a faulty oil pressure sensor connection. The wiring harness had developed corrosion at the connector, causing intermittent false readings in the oil monitoring system. This triggered multiple warning lights and created confusing signals in the instrument cluster. The repair involved: Testing the oil pressure sensor circuit, Cleaning the connector terminals, Replacing the damaged wiring connector, Recalibrating the oil monitoring system This was not a serious mechanical issue, but leaving it unfixed could mask real oil pressure problems in the future. The repair took about 2 hours at the dealership service center. For the VW Taos specifically, the oil pressure sensor is located near the oil filter housing, making access relatively straightforward for diagnosis and repair. Would recommend having the dealer check the wiring connections first before replacing any components. The car has run perfectly since the repair with no warning lights or false oil pressure readings.

Thanks for sharing the details about your Tiguan repair. Dealing with a very similar oil sensor issue in my 2023 Taos right now. The symptoms match exactly what you described, false warnings despite proper oil levels. Good to know it might just be the wiring rather than a full sensor replacement. Quick question, do you remember roughly what the repair cost came out to? And has everything stayed working properly since the fix? Just trying to budget for this and make sure its a lasting solution before heading to the dealer. The car maintenance schedule shows Im due for regular service soon anyway, so might tackle both at once to save time.

Just wanted to follow up on the cost question. Took my VW Tiguan to the dealership and the issue turned out exactly like suspected, a loose connection in the oil level sensor wiring was causing those false readings. The total repair came to 95€ which covered diagnosing and fixing the faulty cable connection. The best news is the automotive oil monitoring system has been working flawlessly since the repair three months ago. No more unusual warnings or oil pressure alerts in the dash. Getting the engine oil readings correctly now makes a huge difference for proper car maintenance tracking. If the symptoms in your Taos match what I experienced, sounds like you might be dealing with the same connection issue. Smart thinking about combining it with your scheduled service, could save you an extra trip to the shop. The oil signal problems are definitely worth getting checked out sooner rather than later to ensure accurate monitoring.

After getting that helpful advice, I finally took my Taos to a different mechanic who specializes in VW diagnostics. Just like suggested, they found a corroded wiring connector causing the sensor issue. The repair was straightforward, they cleaned the terminals, replaced the damaged connector, and recalibrated the system. Total cost came to 120€ for parts and labor, slightly more than expected but worth it for peace of mind. The whole car maintenance process took about 2 hours. They also performed the scheduled service I was due for, which made sense to handle everything at once. Its been two weeks now and the oil detection system is working perfectly, no more false warnings or error messages. Really glad I got a second opinion instead of immediately replacing the entire sensor. The new mechanic proved much more thorough in diagnosing the real issue. For anyone else seeing similar oil pressure warnings, definitely get the wiring connections checked first before jumping to sensor replacement. Sometimes the simpler fix is the right one.
