2008 (New Shape) 2.0 Hdi Very Low Engine Oil Pressure

[bob lawrence]

Hi all, just joined and would like your help with the following problem. 

2008 (new shape ) 2.0 HDi bought 3 months ago with 37,000 miles on clock, so have no previous knowledge. Thoroughly pleased with it but just had a fault show up, it being :- an audible warning followed by the following message

'Very low engine oil pressure' and the engine cut out. This happened when stopped at a junction quite close to home with no vehicles behind so no immediate problem to get moved. Overcame initial panic 

And switched ignition of then turned the key and it started ok and seemed to drive home normally, ie didn't seem to be any lack of power due to be in a limp home type mode.

Besides the need to get it sorted I wonder if this could happen whilst driving, not stopped and also will be towing a caravan for a month in Europe beginning June this year. 

Car bought now due to previous c5 becoming unreliable and not wanting to chance it in Europe!!!!!!!

Any help will be deeply appreciated 

Thanks 

Bob

Have you checked the oil level on the dipstick?

Hi, thanks for replying, yes, fault occurred yesterday and first thing I did this morning. Level ok. Since this posting have been making enquiries and my local garage checked with diagnosis and came up with fault code P0215 along with a description which seemed unrelated to the fault. 

Input this code on line and others with same fault pointed to fuse box under bonnet. Rang dealership and they said fuse box, I was given a 12 months warranty with the car which covers this fault, luckily. Now booked in for next Wednesday, keep you posted.

Seems to be a common problem on the later C5s. Apparently the trouble is caused by the fuel supply relay which is part of the fuse box. Replacement is the answer.

No further problems until the day when I was due to take it in then cut out 5 times that day!! Warranty did in fact cover this fault which would have cost £196. Can't fault my local Dealer, bought from dealership 25 miles from home but able to take it in to local dealer. Changed fuse box and even washed the car.

 Changed fuse box

Fingers crossed that the problem has been nailed.

Try changing the oil filter, also that model requires frequent fuel filter changes.
