406 2.2HDi 2002 Imobilised

[mjb]

This is going to sound crazy but two people on the Coupe forum tried this within 48 hours of each other and it worked both times:

"What he asked me to do was to disconnect the battery, turn the key in the ignition as if I were starting it - hold for 10 seconds, switch off, switch on - hold for 10 seconds, switch off. Leave for 3 minutes then reconnect the battery.

The indicators flashed as if I'd used the fob, I walked round to the drivers door with a somewhat unhopeful demeanour, looked at the omni-present immobiliser light and it was off! As was the engine management light. She turned over perfectly and the fob is working again!"

Was that posted April 1st perchance?

Well I am going to give in.....after further examination, I have found all the wires and connectors in the footwell are beyond repair. So i am having the car collected tomorrow and the electrical magician can sort it all out.
I also hope it will cure some of the other niggles I have had with the car......
If not, it will be up for sale and the end of my peugeot journey....

piss poor design, workmanship and a gallic shrug.....

Nope it wasn't, both had checked under the carpet expecting the BSI connectors to be soaked but was fine, someones mate or mechanic suggested it it sorted them both out, does sound crazy but there we go.....

Well I finally got my car back from the electrical man......
It starts runs and seems to go ok, but if you rag it, the EML comes on, goes off after a few miles while you drive nice and gentle.
And now the 'Anti polution system defective' message is nagging me
Oh and as a special, a new fault.....the sat nav is not selectable from the menu
I just dont know what to do with this car....sell it or throw it in a ditch
And I still dont know what caused the original fault that imobilised it, the repair man suspected it was the soggy coroded wires under the drivers carpet.
But what confuses me with all that electric shorting out and creating faults, why did not one single fuse blow?

Have you still got the particle filter?

Because it's mux, and all the signals got screwed up, rather than shorts between various circuits. Sorry to hear it's still giving you gyp

Yes doggy, all my plumbing is still in place....

Thanks for the explanation Steve......it kinda makes sense now I think about it
