Random oil warning alarm, part 2 (boschman ??)
Hello, i am a new to this forum. I wonder if anyone except bhughes with his post on 06-13-2004 got the same problem. i will quote bhughes:
"1997 Golf, 1.8L gas. The oil warning buzzer goes off quite regularly, under systematic conditions. Under 2000 RPM, no problem. Just over 2000 RPM, alarm may come on at random. Alarm will stay on unless I rev to about 2500 RPM, then it will go off. I changed the oil and filter. It seemed better for about a day, then started again. There are 2 sensors on the oil filter housing: one for low pressure, and one for high pressure. I suspect one of the sensors, but I don't know which one. Has anyonw else experienced this?"
Well, i have a '96 golf 1.8 mono gas and also a '90 Jetta 1.3 gas electronic multiport injection (yes i live in Europe) who both behave the same way...
(as much as i see the 1.8 engineblock is very similar with the 2.0 engine found even on '92 audi 80 (b4) of a friend and the 1.3 block is similar to the 1.4 mono injection found on MK3)
To be more complete, the oil lamp flashes/beeps when engine is warm, starts to beep just above 2000rpm and extends up to 2600 when engine is warmest. Though when it flashes/beeps if i go over 2600 rpm and then drop it under 2000 (pressing the clutch to dissengage) it shuts up . Anyway it is annoying because this corresponds to 80-100km/h in the 5th gear.... Interessting fact is that when using engine break on steep downhill roads it never complains!!!
Oil level ok, 10w-40 recently changed with filter, as i previously used on golf and 15w-40 on jetta, tryed on jetta with thicker oil, same effect.
Forgot to mention that the engines work fine....
also double checked with other oil pressure sensors of the same kinds (brown insulation 0.15-0,45bar and white insulation 1.6-2.0bar), same behaviour...
Believe that the problem is purely mechanical but i am not shure if a oil overpressure bypass valve can behave this way....
So i came to the conclusion that oil pump or the camshaft/piston bearings might be weared (as both cars have a little over 200k kilometers) but still searching for other opinions due to the incredible coincidence of the problem. (on the golf it appeared over winter as i used it less frequently and the jetta was recently bought, knowing about the problem)
sorry for the book and hope to hear good news
