Hi de Hi campers,

Went to see a friend today and 5 mins into journey, my mig went into limp mode, reduced power etc and rev counter died, exactly as per

http://www.omegaowners.com/forum/index.php?topic=81429.msg1072791#msg1072791

Limped car home, got codes read at a local garage, they have ordered a crank sensor. Came home, read through threads and now slightly concerned that new crank sensor may not be the solution.

Mig was serviced in last few months and apart from going into limp mode when stationary (i.e idling) and throwing up P1635 and P0400 codes runs fine. EGR is clean (although if you read the forum threads EGR never causes P1636 or P0400 anyway) although mainfold is filthy.

Car runs very rough atm as if it isn't firing properly and quite alot of white smoke exitting exhaust.

Any help would be appreciated. I am aware that DTi's aren't that plentiful.

Regards

Neil

P.S Found this which seems to fit the bill in a previous thread, any thoughts

Update,

New crank sensor was fitted which hasn't solved the issue as thought above. Old sensor was fine despite thowing up crank code (need to double check resistance on old one to be sure).

Car taken for another spin and car went into limp mode again. This time threw up two new fault codes relating to MAF P0100 which was unplugged before test drive anyway, then car was started and MAF replugged in. MAF code was cleared and tested and found to be ok (just like the crank sensor so no need to replace that MAF part as just wasting money) and the second codes was P1125.

So down to checking vacuum pump reading at idle wrt servo as per

as well as boost vacuum pressure sensor on the inlet manifold due to P1125 code

Rubber elbow at back of vac pump.

Don't want to get into situation like P6UL K where everything gets replaced and still fault persists

On face value all codes relate to high or low voltage input or open circuits - P0100, P0400, P0725, P1125, P1335, P1635
