Hi
I have been reading through all the posts regarding oil-level indicator problems, in preparation of my weekend investigation into the cause of mine permanently being on over the last four days.
Most of the posts here seem to suggest that a failure starts as an intermittent thing and ends up as a permanent fault. The suggestion is also that on physically checking the oil level the indicator goes away for a while (60 miles?), as the act of opening the bonnet resets the sensing system.
My fault has neither of these attributes. Whilst driving to work four days ago the yellow oil can accompanied with the word ‘Low’ popped up and it has not gone out since. It returns instantly the car is started. I even topped up the oil a little even though it needed none, just to see if there was an effect.
My question is this: does this instant fail behavior suggest anything particular for example a fuse, broken wire, loose connection, or is it perfectly possible for the sensor to fail in this way and the bonnet reset system to not have any effect? Any advice gratefully received.
BTW I should mention this for completeness, although I am sure it is not connected, my coolant level indicator is showing randomly and mainly in cold weather. I am almost certain that this is due to the probes becoming oxidised as they dried out when the cam-belt was recently changed. That and the fact that I used distilled water during the refilling (possibly fewer ions to conduct electricity than what was present in whatever Audi used at the initial fill?) In any case I’ll be attending to this too at the weekend.
