406 Hdi warning lights

Post by Peter.N. »

When I first bought this car about 4 years ago the air bag light came on intermittently but has since been permanent, the 'low brake fluid' light joined it sometime later now I also have the 'seatbelt ' light on as well. I have disconnected and cleaned all the plugs with thin wires under the driving seat, I assume the thick ones are for the electric seats, I still have both lights on, I cleaned the brake reservoir plug and that light now seems to have gone out. Any suggestions except put the Lexia on it as mine is still not working.

From my experience, more than one electrical problem then I'd look towards the source - battery and earths. A bad earth or weak battery can cause all manner of electrical gremlins, even if it starts the car OK.

The airbag/seat belt lights are probably the wiring under the front seats? but to be sure it needs plugging in to a diagnostic tool.
The "low b/fluid" is a regular 406 "quirk", replace the small "handbrake on" switch under the hand brake lever.Its a horrible fiddly job and the centre consul has to be lifted up. Make sure you get the latest genuine switch from a Main Dealer.
