Help !! "MIL" light on...

[kam]

hello again...
1st problem with my cerbie...
got home ok.. popped back in to the car and..... the MIL light comes on with a beeping noise.. didn't start.. does this mean i have to call out an engineer??

Hmmm,

Did it stay on or just beep intermittently? Mine beeped intermittently but only VERY occasionally, turns out it was one of the lambda sensors on its way out. . Covered by warranty . I was told this light comes on if the mixture is not 'stoichiometric' i.e. lamda <> 1 (within certain limits).
Joolz/Danny correct me if I am wrong on this

If the above is correct then driving the car will burn out your catalytic convertors.

Best bet is to have it trailered to a dealer (or good independent) who will be able to plug a laptop into the ecu to find out what the fault is.

Hope this helps

Rob.

thanks Rob.. although this morning it started first time no lights on... strange wouldn't you say ??

Mine used to beep occasionally when I was going along although most of the time it never made a sound.

If it does it again I would get it checked out for peace of mind, it could just be a simple electrical fault but then again it could be more serious.

Could also be your alternator on the way out.
