Actually i do not get a blinking, meaning even with a hot engine and
idling now warning occurs. With a cold engine the same, and also when i
rev above 2600 rpms everything is fine. BUT when the engine is hot and I
rev above 2600 at some point, not right away the buzzer+warning light
gets on. A small tip on the accelerator to bring the engine at about
2800 stops the buzzer/warning light. Going then back to idle no
blinking occurs. I believe that there is certainly a low oil pressure
problem, as at 2600 or 2800 the pressure is not supposed to be around
0.9bar but rather 2 to 3 bar. I am certainly above 0.3bar while idling.
The 0.9bar switch is new. What is strange is that the change from the
0.3bar switch to the 0.9bar switch occurs at 2600rpm and not at 2000. I
tested it by disconnecting the cable to the 0.9bar switch.
Thanks
Thomas
