3.2 oil pressure light randomly flashing

Recommended Posts

3.2 in my Touareg has a random oil pressure light flashing. Usually after sitting running for a while. Dealer said pcv. They replaced it (it's under warranty) and it's become less frequent but still definitely a thing. And ideas?

There is a difference between low oil and low pressure, yes lack of oil can cause low pressure but also blockage can as well.

 

I would start with replacing the sensor, they are situated on top of oil filter housing and do not cost a great deal and easier / cleaner job than dropping the pan. If light still continues to flash then time to drop the pan I would guess.

 

How many miles has it done?
