    as above chaps, keeps throwing the engine management light on (happened twice now in two weeks)...will this affect the MOT due next month? also i'm guessing its more than likely a straight replace item once some poor sod has got it out...it says in the fault log, pre CAT if that helps?

    Also any other issues i'm likely to suffer?

    wierd man. This on the A3 or S3?

    I know if the sensor heating fails it'll effect it. Perhaps worth checking the wiring connection, and if it's OK, look at a new sensor perhaps.

    mechanic i know says its fine for emissions if its just the heater which this seems to be...... interesting conflict here mate.

    It's going into Audi tomorrow for the roof to be done and i've cleared the fault, hopefully it will surface again and i can blame them :) (they have to drive it all the way across the city to the bodyshop ;) )

    cheers John.....its on the underside of the mani on ours though isnt it.....think ill chuck it to my trusty neighbour as he'll have a ramp and hot spanners in necessary.

    looks so much easier on the 1.6 engine :)

    i gather this wont harm the car?

    errrmmm I was "told" that it can affect the catalyst

    I don't know how,

    anyway it will affect your fuelling for sure

    yeah it will be the same as if the SAI was taken off the early models, think it burns excess fuel to stop it hitting the CAT and destroying it from cold (as they CAT isnt at its operating temp)

    Yeah, it is a bit of a bitch to get to, but do-able. Access is much easier with the rear charge pipe support removed. Changed mine twice now... lol.

    I always use my trusty adjustable.
