Problem with oil pressure
I Have a problem with my Astra (04 reg) 1.7 CDTI,
In brief, the oil light comes on at different times, usually after a 30 miles or so. It flickers on and off, and if I take it out of gear it goes off, when I put my foot down, it will come on again.
It has been to one small garage, who found it had a oil leak around the Turbo. (They recommended I take it to a larger garage that worked on Turbos).
They replaced a gasket and a valve at the turbo, and cleaned out the oil lines of build up.
I got the car back, it did about 80 miles (different trips), and again the same thing with the oil light while on the motorway.
I pulled of the motorway and the light started to stay on more and more,
I called out the AA, they could not find anything wrong with the car, and by the time the AA got there the engine had cooled so the light did not come on.
I got towed back to the garage, they ran some diagnostics and could find nothing, they attempted to change the sensor, but after much deliberation decided it was not that.
They did an oil change, saying that it may be the oil getting too thin when it gets hot. And gave it back to me.
The car has done another 55 miles and the light was flickering again just before I got home this evening, (it did flicker more as I drove over the speed humps just by my house)
Can anybody shed any light on this problem?
Could it be the oil sensor?
Could it be the Turbo?
What does anybody recommend?
Does anybody know any Vauxhall specialists in or Near St Albans?
Thanks for the help
