    Haldex help

    basically i only have 2 wheel drive at the moment and the traction control light is on the dash all the time. fault code is 01324 control module for all wheel drive, j492 no comunication.
    Ive done a search and found a couple of things. First off i cheacked the conection plugs and all are in good condition. i cleaned them anyway.
    Next one was the earth strap. I cant find one on my car at all and there are no signs of one being there. Can any one tell me if all s3s are ment to have one??
    Oh the fuse is fine too.
    Other than that is it the haldex controller itself?
    Any help would be appreciated. Thanks in advance

    What year is your S3 and have you serviced the Haldex recently?

    Last time I saw this fault, the loom plug for the haldex had gone bad, all corroded inside and was causing the problem.

    Cut the loom plug off, and soldered the wires instead. Problem solved.

    Mines a 2001 and it doesn't have the earth strap thinks it's pre face lift or something not sure. But I know not all have them. My Haldx isn't working either. I even added a earth strap on mine didn't make a difference. Just don't work and with the power ive got 1st 2nd and 3rd gear spins just can't get the power down.

    Goodluck with this, I've seen a few attempts, and they end up crash and burning!

    I had the same problem with mine. I ended up buying the haldex performance unit. It was certainly the best choice. It drastically improves the power you can put down in 1 st gear and you notice faster throttle response throughout the other gears. And subject to what people might say it doesnt turn your car into a drifter in the bends as long as you go in and oot under control. Its easy to fit and comes complete with instructions. Be sure to check your haldex oil level after fitting it. If its low then look at either topping it up, or perhaps replacing the filter and fluid. If this hasn't been carried out at the regular scheduled intervals, this can throw your haldex out of sync resulting in the problem that you have now.

    check the plug for the controller. welly took one off and took it apart and it was corroded to death, re-wired it and it worked.
    just a possibility.
    and yes a tt controller should work.

    Well remembered that man.

    Bottom line, it's exposed to the elements - electrics and rain aren't friends. It's an easy job, and will only take 2 mins to check to be honest, I've got some photos somewhere, I'll have a look now.

    Hi
    Was looking through old threads because my A3 3.2 quattro 2004 8PL has the esp light on and a specialist has told me its the haldex control unit.
    How was your car after the performance unit was fitted?
    Any advice appreciated.

    Hi mate.. Your car is an 8P so the newer model to this. Better to post In the 8P section as the Haldex is Gen 2 in the 8P. But like these lot, get it scanned for faults and work from there instead of shedding loads of money on a controller. Check the connections too.
