What is the oil pressure channel number for Volkswagen?
2 Answers
Volkswagen's oil pressure channel number is data stream group 140. Below is the relevant information: 1. Oil pressure: Depending on the model, oil pressure may vary. Most models require around 300kpa, which is generally normal. Insufficient fuel pressure can lead to difficulties in starting, stalling, and lack of acceleration. 2. High-pressure direct injection injector: The high-pressure direct injection injector is supplied with high-pressure fuel by the high-pressure pump, which distributes the fuel to the injector via the high-pressure fuel distribution pipe. Low-pressure fuel is supplied by the high-pressure pump's guide connection device, and the fuel enters the low-pressure fuel rail.
I've been repairing Volkswagen cars for almost ten years. The oil pressure channel numbers in diagnostic tools are usually 001 or 003, located under the engine control module. You can connect to the onboard system using VCDS software, select 01 Engine Unit, then enter the measuring blocks function and input 001 or 003 to directly read the pressure values. There are some differences between models like the Passat or Golf, but 001 is commonly used as a starting point. The pressure value should be above 0.3 bar at idle and maintained at 2-4 bar while driving to be considered normal. If it's consistently below 20 psi, it could indicate issues with the oil pump, clogged filter screen, or even oil leaks. I remember one client who neglected checks and ended up with severe engine bearing damage requiring expensive repairs. Don't forget to change the oil regularly – oil that's too viscous or degraded can also affect pressure. Safety first, using tools for monitoring is simple and quick.
