Strangeness

Post by rwb »

Here's what happened:

The key button wouldn't unlock the car, so I had to unlock it by putting the key in the door.
The immobiliser light, engine management light, and parking brake light were on.
Put the key in and turned it, cranked but wouldn't start.
MFD was squeaking but not on, nor was the climate control display.
Those three lights stayed on when I took the key out.
I put the key back in, and tried again, and left it in position 1, still with those three lights on.

I took the handbrake off and put my foot on the brake pedal. The three lights went out and the battery light came on. The car started.

Now the ABS light is on solid and I get "ABS brake system defective" on the MFD.

Help!

I'd pull the connectors apart anyway and check for any corrosion.
I've also heard of the ignition barrel going faulty and causing weird goings on, may be worth having a search on related topics.

That's right, under the carpets there's a layer of foam (read: it's a bloody sponge, perfect for soaking up water) in which there are some critical electrical connectors.

Well bloody done Peugeot, absolute genius.

Next question: How do you get the carpet up?

The carpet goes underneath a plastic bit. The plastic bit has a screw in it, but removing the screw doesn't seem to loosen anything.

(It did unlock on the button this time though. But now its raining again :cry: )

(Peugeot replaced the key ignition aerial last December.)

Come to think of it maybe this has been on the cards for a while?

Haynes for D8: the seal pulls off, then two screws further forward which also go through the plastic moulding ar the righr of the pedals need to come out, then it "unclips" i.e., pull it as hard as you can and hope it doesn't break.

In the mean time, parking with the handbrake off seems to keep it happy.

OK, I can get the clips out (prise the plastic up against the sill from outside the car) but I can't get the top of it out where it goes up behind the bonnet release and the underneath of the dashboard. Just pull? (It hurts my delicate office-working fingers :cry: )
