1.8T oil pressure warning
Got an '01 AUM, recently did a service and have been getting intermittent oil pressure warnings ever since... usually when gentle driving round town, between 1.5-2k RPM, or after a decent run and the revs are dropping again (70mph is 3k RPM, usually pops up when it drops back below 2k). The warning always clears itself after a few seconds and the car is running absolutely fine.
I've noticed my oil pressure sensor is leaking oil quite badly and I'm led to believe once its leaking oil through the sensor it's fair to say the sensor is dead and needs to be replaced?
Gone from 5w30 to 5w40 this time around, fully synthetic Shell Helix, VW 502.00 spec. Pick up pipe (and sump) were replaced just before Christmas by myself with genuine parts so I'm certain that's not the issue. Oil is changed every 6 months or so, always fully synthetic and always to VW spec. Oil pump was visually inspected when the sump was off but I didnt remove it, everything looked gravy but there's only so much you can see without removing the pump I guess 🤷♂️
Ordered an oil pressure test kit today, gonna be changing the sensor and doing a pressure test this weekend... is there anything else I should be aware of? I know the older 1.8Ts are prone to sludge but I've never noticed anything undesirable in my oil.
Can anyone advise what oil pressures are normal for a 1.8T please? In PSI not Bar preferably. Thanks!!
