like many my Oil pressure gauge dosent work, it was working intermittantly but now dosent work at all. Iv ruled out the easy fixes and it looks like being the pressure sender unit on the back of the block. I find it unlikley that the unit will have failed (after working intermittantly for a while) and i think there may be a possibility its simple a bad connection at the sender as its been exposed to all the elements for the last 8 years.
Can someone please guide me to exactly where it is on the back of the block? i.e which side/how far up etc?
Also what sort of fitting is it to the wire to the sender? if its a plug conncter or simlar then is it possible i could clean it up with the engine and sender insitu? or is it that hard to get at?
Lastly how much is a replacment sender unit from renault? Ball park only please
(I will try to phone renault but they very rarely manage to give me a price despite providing Oval plate etc)
