What is the sign on Volkswagen that looks like a faucet?

First, it shows that the oil pressure is not enough to satisfy the oil lubrication, so it must be checked and maintained when it appears. It is generally necessary to check the threaded end of the oil pressure sensor for oil loss, oil stain, grounding or damage. It is recommended to repair it as soon as possible.

Second, it is a fault signal of the emission system. The main problems may be poor oil, incomplete combustion, dirty throttle or faulty ignition coil. Go to 4S inspection as soon as possible.

Third, the engine alarm light (please see if it is yellow in the picture), the general engine alarm may be that the throttle is dirty and needs cleaning. Or the oil is not good, I suggest you check the fault code with the computer on 4S as soon as possible, and then troubleshoot.
