Hello, I recently bought a 2014 Passat tdi with 100k miles from auction, it’s got all sorts of problems as it was not properly maintained, but currently I need to change the oil pump and pressure sensor/switch because I’m getting the low oil pressure turn engine off light on the dash, I was able to get the sensor out but I’ve been looking all over and can’t seem to find the location of the oil pump and how to replace it anywhere, any info would be appreciated!
