    My reverse lights stopped working, and triggered the warning light on the dash to come one. To cut a really complicated story short (still complicated) heres a summary of the prob.

    In reverse gear - No Light (with engine off, on acc and engine running)
    Switch the bulb holder and bulb onto fog light side - works ok as a fog light
    With the fog light bulb and holder on reverse side - Not working

    So it's not the bulb or the holder.

    With everything back as normal, with sidelights and foglights switched on, I get 12v accross the the sidelight and fog light +'ve terminals but at reverse side 12v is not being supplied to reverse bulb (sidelight is ok). I've tested it at the distribution block behind the boot panel and theres no 12v at the harness and continuity of the wires between the harness and the holder are ok.

    Since testing voltages the warning light on the dash has gone out but the light still doesnt work. :wtf:

    So is it possible that the reverse gear sensor is faulty or possibly the fault sensor being to clever.

    The only thing I haven't tried is disconnecting the battery. I spoke to a guy at Seat yesterday (sunday) as I happened to be near the dealers and he said he hadn't heard of faulty sensors on the new leon but said it's always possible and that I would need to book it in to get it fixed but if i can save a 100+ miles round trip I will.

    One thing that would be really handy to know is does the reverse light come on even just with ignition or does the engine have to be started? :think:

    Hi Graeme
    Reverse light does come on with car on but not running and with reverse gear selected .
    Does sound like the reverse light switch has either gone or come loose to me dont know where its located though.
    Does seem strange that the warning light has now gone out now though

    Brilliant thanks Simon.. I won't have to pester my beautiful assistant anymore to put the car in reverse for me :happy:

    I think i'll just have to take the airbox off tonight and have a proper nosey as it should be somewhere obvious once I can see properly. I'll get pics and hopefully seat will just post me a sensor or something or at least allow me just to drive up and get it fixed while I wait on a saturday or something.

    Yeh the warning light is weird.. strangley I feel like I would prefer it to stay on since there is a fault. I might disconnect a sidelight and see what happens.

    Simon, after the warning light went out did keep testing the bulb and checking it but it never worked.

    Last night though i realised as i was reversing out the drive it was working again.. so i've still no idea what was wrong or how I fixed it apart from using a multimeter on it.

    It works for now though.. best leave it in case i break it again.

    Reverse sensor

    mate the reverse sensor is below the battery, take the battery off and the covers, and then you should find a rectangualr part which is small which a wire like a pulg connected to it, they normal break off leons, its a lil tricky tryin to put a new one back on as its linked near the gearbox, so some mechanic help is advised.
