Car had been sitting for last yr in garage. Jumped started, and began using.
Oil Pressure light/buzzer started coming on.
Was bringing in for service anyway – local shop- German oriented– not dealer. Checked car out fully, no leaks, etc, changed oil and changed oil pressure switch. Buzzer/Light still coming on.
Brought back in and he dropped oil pan and cleaned pick up screen – said it was 40% blocked. Pressure tested with gauge and pressure was fine.
Light came back on after 1 day.
Brought in again – replaced pressure switch 2nd time and tested pressure again, was fine. Flushed oil again. Road tested – no problem.
One day later. Buzzer and light comes on again.
The light and buzzer come on after 3000RPM, initially, come to stop sign and goes off, then back on again on 3000RPM. Once car is warmed up, will usually NOT go off at stop sign. If I shut off engine, and turn on, Buzzer/light comes on at 2000+RPM. And stays on. Sometimes it does go off at low RPM, sometimes not. Intermittent
Next – disconnected pressure switch and wired to ground – Worked fine for 1 day, then same problem with Buzzer/light.
What does system work for a day, then act up?
Do I have a bad wire? How to track down?
Is it the cluster? (Why?) Can I disable the light and buzzer in the cluster?
Any ideas greatly appreciated.
have the same problem?
