Oil Pressure

[adrian996]

Hi Andrew. It's your oil pressure sender. Mine went at 9k miles. Exactly the same symptoms as you had - both on my dashboard.........and in my pants. Anyway, it'll cost you almost nothing to replace - compared to what you obviously thought might be wrong. And.....relaxxxxxx.........

^^^^^^^. What Adrian said. It is a common problem. I would just get it changed.

Thanks Adrian & Richard - feeling much better already!!! Andy

Had a real shock driving to the airport on Monday - suddenly got a low oil pressure warning and watched as the pressure gauge dropped to zero. Just about to coast to a halt and switch off, when the needle went right back up to 5 (bar, presumably). Anyway, I still pulled up and switched off.

Nothing externally wrong with the car (oil leaking etc) and when I put the ignition on, the oil level was as before, although the oil pressure gauge was registering 3 bar even though I hadn't turned the engine on.

I phoned the mechanic from the Indy I've used for years, and after going through a series of 'check this, check thats', he reckoned it was a faulty pressure sender. On that basis I drove the remaining mile to the airport and have gingerly driven it back this evening.

Car is driving absolutely fine, no untoward noises, temp normal etc. Only the oil pressure gauge is different, going to 3 bar when the ignition is on but engine not running, showing 2.5 bar on tickover when hot (was 1.5 bar) and hitting 4 bar by 2000 rpm.

Anyone recognise any symptoms before I get it looked at?

Almost had to change my pants just reading this. I am pleased for you.

Can anyone clarify what pressure the gauge is meant to show in the ideal conditions please. I have a C2 2003. When my engine is at full working temperature my gauge shows about 2.25 bar at idle, rising to about 3.75-4 bar at 2000 revs. Thereafter when driving at about 2,500 and above revs the gauge is sat firmly at 5 bar. This has been the same for the 2 years year I have owned the car - is this normal or is my pressure sender suspect?[&:]

Your figures are all perfectly normal.[]

DRDT, your pressures are exactly the same as mine are now, but they were different before the sender incident (eg when hot, idle was 1.5 bar, now 2.5 bar, anything over 3k revs and the needle is now stuck at 5 bar whereas it was about 4-4.5 previously). Andy

I have similiar oil pressures to that, but it sound like it normalish.
