"dabin" <u43820@uwe> gurgled happily, sounding much like they were saying:

Oil LEVEL light? Or oil PRESSURE? The latter would be by far and away
more likely - damn near every car ever built has oil pressure warning,
very few have level warning.

If the beep pairs with the light, that would suggest to me that they have
the same cause - and, probably, the beep is an audible backup to the
light.

If there's no mechanical problem or symptom, it'd suggest an electrical
issue - in this case, possibly the wire to the pressure sender chafed and
earthing on the clutch cable or gear linkage?

Well... the audible beep is probably telling you you have low oil
pressure. Even VW Golfs used to do this.

And you depress the clutch when stopping.

So, when warmed up, in neutral, without the clutch depressed and simply
idling, are there any warnings?

If there are, then the car thinks it's not producing sufficient oil
pressure, so either it isn't or the sender is faulty.

If there aren't, then there's something odd electrical going on most likely.
