only on tick over once hot tho? am using 15-40 ... New breathers, new oil drain pipe on charger.... Any ideas ?.
one of the pressure sender or wiring to on the head probably
Both are new VAG units, and the wires look fine! 1 is longer than the other so cant get them mixed up!
maybe wiring to the clocks?
or maybe an oil pump issue?
Bringing this back as it's still a issue! A oil pressure test showed good results! Also once hot the buzzer will sound (no matter how being driven). If the revs are below 2k!
check the resistance of the wires with a multimeter, should be pretty close to zero. Those two wires go right to the connector on the back of the clock, Haynes shows which pins.
Other than that and assuming the pressure senders are both OK and the correct ones then I'd start suspecting the clocks themselves.
I had an issue with my clocks doing this in my mk1 golf. Changed them, problem sorted.
