Hi All,

I have a T4 1.9 with the flashing oil lamp fault. Only just spotted it as the lamp had been painted over to hide it.

1 - Read the threads here regarding alternator wiring. Checked, found one broken and repaired it. Now have oil light off once engine starts but comes on as motor is revved and buzzer too.

2 - New oil pressure switch has been fitted alongside filter by previous owner. Rumour has it there are two, one high, one low pressure. That would fit my problem with the high pressure one being faulty.

As an electrical bod, I'm determined to get to the bottom of this. Does anyone have the electrical wiring diagram for the T4 diesels ? Anyone know where the second switch is located?

If I can sort this out I'll write a complete check list out with pics for use as a stickey. This is a terrible reoccuring fault by the looks of it and needs sorting.

Ta
