What's the correct oil pressure at regular temperature (hot) for a diesel engine on iddle? I believe mine is very low, under 1. On last service was detected a leak on the circuit and the oil pump was also replaced.

I believe it's different... but don't know if that's normal (always on 3). I compared others to mine, and they keep at 1,5 (+/-) on iddle and with just a bit gas pedal it rises right up to 3. Mine isn't like that, it only reaches 3 at middle ratio... for instance, if I go on 4 gear below 70 Kmph, even with pedal on bottom, it doesn't get on 3. (my 190D as only 4 gears)

At operating temp, mine is at about 1,5 at idle and up to 3 at rpm higher than idle. It is a 2.5Turbo

Awhile back I think MTI posted the specs in terms of how many bar the oil pressure should read at idle and at full throttle. I searched but couldn't find his post. Anyone remember?

I always thought the higher the better, but maybe I'm wrong. My car after a long hard fast drive will get down to 2.75 at the lowest. If you can't get any details on here you may check the rev.

If i can remember correctly. The 16vlv is the only engine that should stay pegged at 3 while idling.
