ive had a look at the 406 hdi 1999 ive just bought & found a few faults
1. the ignition lights stay on with the key removed
2. if you disconnect the battery them reconnect it the mileage briefly reads 923700.00 then goes to 0000 with a spanner next to it & 000000 underneath it
3. it turns over but will not start
4. you can turn the heater on with the key out
5. the rdio will not turn on with or without the key


any ideas

Does it flash up economy mode active?

it doesn't but it does beep when you try to start it

it doesn't but it does beep when you try to start it & the stop light is flashing

Beeping sort of sounds like an immobiliser. My petrol D8 would do that if I mis-keyed the code.

However yours is a D9, so no keypad. Also diesel so different there too.

If you open up the key - is the RFI chip in there?

Just opened up my D9 key to show the coded RFI chip for the car.

The chip is in red and it fits in the area in blue.

just checked & the chip is there, the guy i bought it off had the key programmed to the car

Had some of the symptoms you have.

First off stip out the ignition barrel and have a look at the switch. mine disintegrated and stuck at poisiton 2.

The key being lit up is almost certainly the immobiliser although my did this after the switch disintegrated.

If you need to get a new key coded, look at around £26 to have the original code ordered from peugeot and £120 for the key including coding and cutting.

good luck.

just spoke to a mechanic at peugeout & he has told me to lift the drivers carpet back & check the 3 connectors under neath the throttle pedal as he is 99% sure that they will be corroded & causing the fault.
i will check this on sat & let you know

I've heard of those corroded connections before somewhere.

This bit of info I just found on the immobiiser/BSi looks quiet good Linky BSi PDF

thanks for that welton, i'll let you know what i find with the plugs on sat

well i removed the carpet yesterday to check the wiring plugs underneath the throttle pedal hoping they were corroded but they are fine so i have removed the bsi & am sending it away to be checked & repaired 2moro.

hope that will get the car running again

well the bsi has had to be reset to factory standard£125 inc vat & postage but i will need to get it reprogammed to the car so theres another £20 for the code & £40 to get it programmed.
hopefully i'll have it running this week

well i put the bsi in today & it still has the same fault so that will have to back to bba but i got a bsi, ecu & key chip from the scrap yard today(foc) & it fired up first try but it will not rev over 3000 so ive gone from one problem to another

it'll be in limp home mode for some reason.

you need to get the fault codes read.
