1.9TD 306 Oil Warnibg light

Hi, A problem with 'P' 306. For some 500 miles now the oil warning
light has been flickering. The local garage have changed the switch and
say the pressure is OK. The flickering persists at all speeds and they
are foxed. I noticed that that electricly the switch is connected to
the anti-theft device on the pump, could this have anything to do with it?

TIA

Hi

Tucked behind the passenger ( Left hand ) side headlight are 3 large wiring
loom connectors, 1 x Grey, 1 x Brown & 1 x Black.

These are the cause of all sorts of electrical faults on Peugeots /
Citroens because nearly every circuit on the car passes through these
including the anti theft device.

Have you checked the terminals are clean & making good connections inside
these plugs?

Notice the classic piece of rubbish design, 1 male terminal pushed up
agaisnt another male terminal, They just twist together, Theres a locking
collar on the plug, Just twist it to undo & do it up again.

The terminals get dirty & then the fun starts with the electrical faults.

Give the terminals a clean with WD40 or similar & a tiny bit of adjustment
with a screwdriver if needed so they make good contact with each other.

Make sure you have the radio code, shut the alarm system down ( Its in the
handbook ) & then disconnect the battery negative terminal first before
undoing any of the 3 connectors.

Might I suggest switch cleaner available from RS or Maplins would be much
better than WD40 which isn't really designed to improve conductivity.
