Question about BMW 7 Series
The most common cause of no- or low- oil pressure indications isn't the failure of the oil pump or a blocked filter (these all have bypasses) but the failure of the sender/sensor providing the input for the sensing circuit.
Apparently, this also applies to the top-end cars as well.
Oil pressure gauges showing an actual range of pressures are far more reliable but more costly to make.
The majority of sensors used are primitive devices using a disk of metal that 'clicks' at pressures above a few pounds to keep the warning away and when these fail, they generally close a conductive path to 'send' the no- or low- pressure signal for the warning.
These are normally not costly items to replace.
