Hi!

Bought myself a real cheap 850 tdi the idea was to scrap it and sell it part by part.. However when i went to get it i noticed its fairly good condition and service history.. And now i am having second thoughts about the scrapping.
The main thing that is wrong with it is the oil pressure (or more like the lack of it http://www.volvoforums.org.uk/images/smilies/smile.gif I have searched all around Finnish Volvo sites for answers to this problem
, but it seems no one has these kind of problems.. Several Volvo mechanics i have interviewed about this case have never experienced any pressure problems with this engine type. I would appreciate any thoughts / ideas regarding to this problem. Engine sounds ok but it cant get oil up to filter. (Sorry about bad grammar and spelling errors.

Take the sump off and check the oil pump pick up pipe, make sure there is not sludge on the mesh- the 2.5 tdi is not known for oil pump failures, in all fairness i never changed oil pump on any 2.5 or 1.9Tdi engine...

Check that the correct oil switch has been fitted i had a similar problem with my Audi an after market switch had been fitted and the pressure variance was 0.2 out so no pressure was showing
