On the turbos, minimum 0.5 bar at idle hot, must peg the gauge at 1500 rpm. Typically you won't see less than 2 bar at idle unless you are stuck in a traffic jam on a hot summer day with the AC on. Peter ___ http://www.okiebenz.com For new and used

Should be about the same -- the reason you normally see 2 bar is that the cooling spray jets that spray oil onto the bottom of the pistons open at 2 bar. Unless you have a really worn engine or a dying oil pump, there is enough flow to open the jets at idle. Peter

OM60x Min specs I believe are: 0.3 bar at idle and at least 3 bar at 3000 rpm. Not sure what a 2.5 runs @ 60. 2200 RPM? So as long as it's pegged by 80 your OK! :-) Seriously though, from browsing the archive I'd replace both the o-rings oil filter to rule out any sealing/gasket issues. IF

Verify that the pressure is indeed low and you don't just have a bad pressure sender unit! Mine did something similar, then dropped to zero and sat there. Replaced the sender, works fine. It is also possible to dislodge an internal seal in the oil filter, which will drop the oil
