VW did with Haldex's help. They put it in the R32. |

Gas tank must be changed out along with both fuel pumps.. About 1400 whether you go TT driveshafts or A3 driveshafts they are about 400 each plus a core charge on the front two for the TT.. rears are new units. rear subframe is 900, but its nice and light aluminum. Brace for rear subframe is 200 I think. rear swaybar is about 150 The control arms show to be different but superscede to the same Rear bearing housings, 350 each side I think bearings and hubs about 150 each side. |

IMO the easy way to go to control this is a standalone controller, just add 12v and ready to rock and roll. |

the only thing that is annoying about the controllers is that it stays locked up too much.. Its like driving a 4X4 truck with a locked center diff... both mine have had that and on dry roads if you forget to take it out of 4wd it really sucks... Also its gonna stress the clutches alot more probably requiring you to do more often fluid changes to make sure you don't kill them. I checked out the wiring diagrams betwen a 3.2 A3 and a 3.2 TT and 1.8t TT and it lookd like you would just have to connect power, ground, can h and l, and a vehicle speed signal or something like that. |

I've got a euro a3 2.0t quat driveline in the shop, been wanting to explore it some more. Maybe when stage 3 is installed and testing is done, I might get to have an awd GTi if I can make it work. |

Transmission with center driveshaft output. No quattro dsg 4 clylinder application in the US so trans would be very hard to acquire, possibly you could combine a 3.2 dsg with a 2.0t dsg bell housing assuming there are the fittings in the 2.0t bell housing, they are there but not machined on the manuals For a manual you luck out as the 02m from 225tt is almost identical to the 02q in the A3. I still have not determined which flywheel clutch you would have to use since they list a different flywheel for the 1.8t and 2.0t for aftermarket applications. Used ones seem to be going for about 1500-2000 Gas tank must be changed out along with both fuel pumps.. About 1400 whether you go TT driveshafts or A3 driveshafts they are about 400 each plus a core charge on the front two for the TT.. rears are new units. Center driveshaft is about 2K for the TT, both are smiliar in length, don't have my notes on me. rear subframe is 900, but its nice and light aluminum. Brace for rear subframe is 200 I think. rear swaybar is about 150 The control arms show to be different but superscede to the same Rear bearing housings, 350 each side I think bearings and hubs about 150 each side. Now the real tricky part.. The rear haldex unit has to be matched to the final drive in the transmission.. So if you use a 3.2 dsg with a 2.0t bell housing you can use the 3.2 haldex unit. If you have a manual and use a TT trans then you must use the TT haldex unit. The TT haldex unit unfortunately does not bolt up to the A3 rear subframe so you would have to fabricate brackets. Also then if you use the TT haldex unit you would need to use the TT rear driveshafts. The fronts appear to the be same. Both haldex units are about 5K from the dealer.. I think about 2K used for a TT one.. if you find a 3.2 haldex unit used.. you are one lucky bastard, no vw/audi specific yard I have contacted has had a wrecked A3 3.2 yet. Now the other problem with the TT unit is that its the old haldex and it may or may not communicate with the rest of the car to pick up the wheel speed. IF it does not then you will need to pick up one of those standalone haldex units.. This is good and bad.. This basically makes the haldex unit locked.. Which means no delay till it locks.. However good and bad it also has temp sensors and other thigns.. So if the clutches in the haldex unit start to overheat it will disengage and you are back to only FWD til it cools off.. So at a hard track day you may start off AWD but end up FWD. With haldex really tied into the system it will be constantly engaging and disengaging when you do and don't need it. Labor really wouldn't be that bad if it wasn't for possibly fabrication of the rear diff hangers. Oh and you woul dneed a new turboback exhaust since the whole system is different What HPA charges is a little high.. You can get a wrecked TT for about 5K right now and there are many people who can barely change their own oil who have installed it including cutting out and welding in an R32 floor pan into their mk4 1.8t in about a weekend. If you have a whole wreck its really straight forward to do in a Mk4.. Due too many variances in the setups for fwd vs awd in the A3 its slighly more complicated and alot of bugs need to be worked out. Its not impossible and it does not have to be even that expensive if you do it right.. And it will get done eventually....... |

I think with a few pictures this could be a DIY
