My oil gauge was doing the usual thing with it working then not workin, put up with if for a while and then decided to wire up my aftermarket stealth 2 oil press gauge as I was starting to get slightly worried, as you do ,not really knowing your oil pressure on a turb car.

So easy one hour fit then to test, what a relief it is to have a oil press gauge that works , responds fast and gives you piece of mind, 20/30 psi on idle when warm, 60--90psi on full rag...another little niggle sorted

nicely done mon frere, always satisfying to sort these niggly things out :D

what does you boost gauge say you vacuum is

-20hg at idle, at the mo 13/14 psi on full rag

thanks i get -20 at idle and 7 psi flat out :headvswal

safety boost?

yes i have spent two weeks trying to find out why. i had a boost leak done that still the same no error codes getting on my nerves now

Oil gauge is my next job, I hope to get the same results as you did mate.

try doing the det sensor mod just in case and see if it comes out of safety boost, its only the price of a resistor to find out , then you can put that one to bed.

thats an idea what resistor should i use

its a 1 megaohm but look here mate

Mine's been going awol over the last week. Started working fine again today. Stupid thing. Need to get some aftermarket gauges fitted over the winter.

the stock gauges are terrible, mine said i was getting just under 14psi whan in fact i am in safety boost

its a 1 megaohm but look here mate

thanks. having read through i spotted this i wonder if this could be my problem

"If you have a code 55 (all's OK), then it means that your Safe Boost Solenoid Valves might be defective."

could always be the case
