    Default Engine management light.

    407 engine warning or service light stays on. The display reads anti pollution fault. I tried disconnecting spark leads one by one, all were the same, each disconnect made it run poorly. My mate who owns it says its running well but using more fuel than usual, and all plugs and leads seem to be good. The light just stays on. Any ideas would be appreciated.

    Ageing O2 sensors or blocked cat.

    Thanks Addo. I guess the o2 sensor would be the cheapest first option. Cheers.
