I've fitted some different clocks to my mk2f, these new ones have a clock and Rev counter etc. but whenever the engine is started then revved, the oil level warning light and chime come on. I'm guessing because the engine doesn't have an oil level sensor, can I fit one to stop this annoying bong, or can I cut the wire?

Any help appreciated

Thanks

Here is what you need to know

Late Spec and Early Spec Clocks

During the production span of the Mark3, subtle changes were made. These changes are largely under the skin, but you my encounter one of them when fitting clocks into a late L/M reg Mark3. Basically later Mark3s ditched the two oil pressure sender system in favour of a simpler single pressure sender that covered both high and low pressure (as opposed to the older method which used a sender for high and a sender for low).

When fitting Early clocks (which would use the two pressure system) into a late car, the clocks will trigger the oil pressure warning light and buzzer. This is because they are searching for a signal from the high pressure sender (above 2000rpm when the light and buzzer will trigger), but due to there not being a sender present, cannot find a signal, and triggers the alarm.

There are a few things you can do to get around this:

Fit some late spec clocks that have the red bar on the temperature gauge, and no temperature warning light. This is by far the easiest method.

Retrofit a high oil pressure sender and run it to pin number 8 on the clocks.

Run an earth to the clocks to trick them, (however if there is a genuine pressure problem, you may not be made aware of it).

Or finally an after-market rev counter.


The good news is that late-spec clocks will fit an early car, as (obviously) will early spec clocks. Just to remind you:

Early Clocks ---> Early Car
Late Clocks ---> Late Car
Late Clocks ---> Early Car

Early clocks are NOT compatible with late cars WITHOUT modification
