In my diesel peugeot 405 I have an electrical problem. The alarm system comes on if I shut the drivers door. There is a red light flashing on the dashboard. If I try and start the car, it goes through the diesel preheat but the starting process will not go any further.

if you look on the steering column thete is a square button you need to get in the car with the door shut, press this button while switching the ignition on, this will turn the flashing lights off


let me know if this helps


cheers big mike

Its the low water warning light. You need to top up your radiator, or check for leaks.

the starting problem has nothing to do with a new exhaust system being fitted,, it could be the car alarm cutting off the fule pump though,,, try reseting the alarm it may have been upset by the work done on the exhaust,,,

the motor in the drivers door has packed up, you will need to replace this for it to work properly.

there should be a switch on the steering couling with a pic of siren symbol on it
you need to sit in the car with door shut
press the button while switching ignition on
this should reset alarm

I had a similar problem with my old peugeot 405 diesel, something electrical was shorting and actually sparking in the engine compartment which in my case the garage fixed very easily. Same symptoms, the speedo flickered at low speeds but stopped at higher speed.

i have a new van but need to remove dent in bumper

may be the water in fuel filter light if it is this is common on these cars replace fuel filter but may still come on

the alarm control unit is fitted under the drivers seat can be accessed from the rear foot well by putting seat fully forward .unscrew the two nuts holding the cover the relays are inside the unit.

this unit interfaces will tell the fuel stop solenoid to release (by applying 12 volts)

the fuel stop solinoid is on the main diesel pump under the bonnet - the exac location on the pump will depend on the make - but it should be cylindrical and have one wire connected to it - (i dont think peugeot were using multi wired coded soleniods in 93)

obivously if your car has the keypad immobilser you will know where this is - if it is the remote alarm immobilser the reciever is in the over head consol near the interior front light
