[teatime39]

I've just serviced my 1990 320i cabby , oil ,filter, plugs, dissy cap n arm,i was given the wrong air filter so couldn't change that ,i have a fuel filter but it got abit dark so will do that tomorrow. My problem is this 1, my engine oil light stays on , i checked the level on the dip stick and its fine 2 , i tried to reset the service lights with no joy , i tried a link between pin 7 and earth , and pin 7 & 19 but nothing happened any ideas .plus there seems to be a slight knocking in the dissy cap ,have i done something wrong , any help would be great...

Hi there, which oil light stays on, the check one above the rear veiw mirror, the pressure one or the service light?

Was the ignition on(engine not running) when you tried to reset the service lights?

Happened to me aswell. Theres an oil sensor near the oil filter disconnect it and reconnect it. It must have moved while you were changing the oil filter .

the light by the rear view mirror .
Yes the ignition on not running . but the yellow n red lights are on at the same time , it did the green light count down ok then the oil service lght came on as the yellow light did .

My check control oil light usually stays on for a day or 2 after a change and then goes out. Don't think it indicates any problem.

The switch by the filter is the oil pressure switch. This works in relation to the Oil warning light on the dash. The light in the check control panel is the Oil Level which is related to the sender in the left hand side of the sump to the front (under the diag socket). Therefore this is either level related, of the level sensor has gone down. I'd say it has nothing to do with the pressure switch by the oil filter.

+1
It some times takes a few times being run up for the light to go out.

As for the service lights, have another go, you have to hold it on for a bit longer for the full reset. It could be the batterys in the si board.

10w-40 or 5w-40 would have been better for the cold weather starts but i wouldn't worry too much

its said it takes 8 seconds to reset , ileft it for about 30 , what way should i do it pin 7 to earth or pin 7 to 19 and how long should i wait, thanks

The oil level light will just be the float in the sender that's got to re-float itself, make sure the level is upto max and go for a good drive to get the oil nice and hot, that's always sorted it out on mine.
