    Purchased for my S3 however did not work, I then discovered that the cabling is different to mine so I am now wondering what it is for. The ad said it came off a 2003 a3 quattro, did the later models have a different controller?

    Thanks!!

    Here is a photo of the cables from my old one/

    That's a gen 1 controller. If the plugs are the same I wouldnt be.concerned about colour of the wires. If its a known working controller and it didnt work, your haldex problem lies else where.

    Check plug on the car, rewire if nessesary, check wiring to the precharge pump too.

    No probs dude, bought the top one pictured and that didnt work, so bought another one (not pictured) which did and is on the car so I am left with this (first one)... contacted the original seller and am assured it works, the other photo is the original broken one off the car :)

    Cars with ESP had a different controller, I fell foul of this when I put an r32 diff in my car, I had to swap my controller onto the replacement diff.

    It's the only thing I can put it down to tbh. I bought a complete 2003 r32 diff and controller, fitted it to my ultra early 99 s3 and it was in fwd, I swapped the controller to my apy one and it was perfect. I've since fitted the r32 controller to another car that had controller issues and it worked fine. The 2 do physically look different aswell.

    so the r32 one (esp) didnt work for your apy (non esp)
    but the r32 worked for an esp car.
    that does suggest there is a difference.

    Just did some research on the haldex.. Gen 1 was in 98 and Gen 2 was in 2002. Thats probably why Benjamin had that problem with the R32 one. I think it will work joe because i dont think they would of changed the haldex controller like that, should be the Gen1 still.

    Ginge if its from a 2003 then its gen2.

    It can't be surely, gen 2 is what's on 8p chassis and mkv cars.

    Gen2 diffs are completely different. The controller bolts to the other side of the unit. My s3 diff and the 03 diff were both gen 1 but the controller was different aswell as a few minor differences in the casting.

    This is the worst case of S3 envy I've ever seen.
