Hi all.
Does any one know if or cars have 2 oil pressure sensors.
I have a dash alarm saying low oil pressure stop engine.
VAS says oil pressure P2 < Limit. So I assume its low. No other symptoms.
Trawling the site it appears the low sensor is at the front of the engine. @Johnny Hotspur GT posted a diagram a few years ago
Any one know where the other is please ?

 

Hello @Frank ( Sunnyside ) ,
​@Whiteman18 , is another scammer, he is not in California as stated in his new member post, he will now be removed, as will our comments shortly.

I will get back to you on the ops, as I believe there is only one.

Thanks Johnny.
I seem to be a magnet for Numpties on this site. Have they nothing better to do. I did realise as it happens he didn't have a clue about my question.....God save us from these people!!
Thanks "Ship Mate"🙂

Hello @Frank ( Sunnyside ) ,
I asked Jason about numerous oil pressure sensors on the W12, and we both agreed from our hands-on knowledge, that there is only the one at the front of the engine, as to why it is called "P2", that might be because of the oil level sensor, and depending on what the actual language of the fault code states, our thinking is that the oil level sensor with it's temperature sensor may be P1, possibly, not sure, and the oil pressure sensor is P2, again, this is just us thinking out loud.

A scan would help.

I would definitely check the plug and or wiring, Jason said that he has seen this plug dislodged from people doing an oil change, as the wiring harness for said sensor runs very close to the oil filter housing.

Thanks Johnny.
I have gained access to the pressure sender. Bit tight but still.
I'm waiting for a long reach 24mm 3/8 drive socket. Then I can have a go.
Looking at the new sender, I now wonder if there are actually 2 switches inside the one item. One switches at a predetermined low oil pressure at idle. The other at a higher pressure if that pressure is not met whilst at higher revs it throws a second warning.
If indeed my switch is faulty and the new one fixes the issue I am going to take the defective one apart and see what is in it.
I will post some pictures once done.
Now waiting on EBAY to deliver my new socket.

So. I now have the socket and now looking into fitting a manual pressure gauge.
I have the M10 to M10 adaptor with 1/8 NPT female hole. I now need pipe with Male 1/8NPT to 1/8 NPT female gauge connector and about 6ft pipe.
