have an audi a3 tdi and the oil warning does not illuminate when engine started

OK if the oil light is failing the bulb test then its very likely that the bulb for will need replacing

you can confirm if the bulb has failed by disconnecting the pressure switch and connecting the terminal to ground

this should turn on the light ( with the ignition on)

if it doesn't illuminate then the instrument panel will have to come out to replace that bulb

it's not a bulb it's a led panel that says the oil pressure is ok then goes off but it doesn't come on at all

Hello Bernard

if this is the message centre type of dash then its still worth doing the oil switch to ground test with the ignition on

if the message then comes up ' low oil pressure'then you know that circuit is OK
