Several good mechanics have checked car and recently oil pressure switch was changed but still issue occurs from time to time

car is still in pristine condition with only 38k milegae and mine from new

Oil levels good , oil is clean ....oil filter is clean ...serviced regularily

this is first issue and repair thats occured and all are puzzled

warning buzzer sounds then red oil warning light will flash ......then disapeear for days or weeks or months till it starts again


is there a another hidden sensor somewhere ? .....any ideas please

You need a good oil pressure gauge fitting to see if you have pressure.

It depends how often the oil and filter is changed with quality oil.

Oil pickup pipe in the sump gets blocked, so sump off.

 

Thank you ...apologies for failing introduction ....rather too wound up worrying about my favourite little car ...

i know the oil filter is totally spotless ....the car has always been serviced by one of a few garages i trust ....but given its age maybe the sump , tubes etc needs totally cleaning and the recomended independant mechanic currently trying to find reason is 100% trustworthy ...he checked everything before he even considered replacing the oil pressure switch
