    Haldex Gen 1 or Gen 2

    Hi guys,

    Quick question - is there an easy way to tell if I have Gen 1 or Gen 2 Haldex?

    I have a 2002 BAM S3 and I know Gen 2 was available from 2002 onwards, but I just want to be sure!

    Thanks,
    Erf

    It will be a Gen 1 from the factory, VAG didn't fit any Gen 2 versions until the 8P A3 and Golf V.

    I'm assuming here you mean Gen 2 as in the version that always puts 20% of drive rearwards?

    Have a look at your controller

    If it looks like this then it's a gen 1

    If it looks like the part on the left then it's gen 2

    Thanks guys. So from what you're saying I shouldn't worry about part numbers if I'm buy a replacement haldex clutch? They should all be the same for all 8L s3's? Should make life a lot easier!

    I believe all of the 8L quattros used fundamentally the same controller. It wasn't changed until the arrival of the 8P.

    You can upgrade the std controller to a performance one, with different characteristics, but the std ones are all the same by generation.

    I understand that the ESP/ASR functions added to facelift S3's were down to Audi, and are not linked to the Haldex controller? The ESP system is standalone and afterall only brakes individual wheels to try and regain stability, it doesn't vary torque to wheels or anything.

    I might be doing it a disservice, but it's really not all that sophisticated. The Haldex controller in the 8L just transfers torque to the rear wheels via the clutch packs when a difference in rotational speed between front and rear wheels is detected. It does this independently and whether ESP is switched on or off on the dash.

    Having said all that, I didn't design the system, so it might be safer to source a controller from a facelift car, just in case there is other interaction with the cars systems.
