Hi have an 07 S3 Bluefin & carbino. Has anyone fitted either the Modified Haldex control unit and or a modified Diverter valve.If so comments please.
Many Thanks
Many Thanks
thebears said:i thought the S3 had a modified Haldex as standard or are you talking about the switchable haldex with 3 settings, sport, normal etc.
klauster said:its the haldex gen II and im about to get it done on mine. Its basically an uprated version, which responds alot quicker therefore makes driving hard more fun and 'apparantly' transforms the cars handling... Im trying to find someone who has had it done to put me off and save me some poe!

Dandle said:The gen II haldex unit is used on all 8P A3s(inc the S3) the 8Ls had gen I. What you are talking about is the modified Gen II haldex controller as offered by APR and the like. It has three different setting and sends more power rearward on the car than the standard unit would at any given time(except max transfer). A;lthough it will not give the car a rear bias it will feel alot more like it compared to standard.

The MkIV Golf-platform cars (old A3Q, old S3, MkIV R32, etc.) come with the GenI Haldex controller from the factory. These cars could be upgraded with either the Blue or Orange GenI HPP (Haldex Performance Part).
The MkV Golf-platform cars (new A3Q, new TT, MkV R32, etc.) come with the GenII Haldex controller from the factory. While similar in design, the two controllers differ in that the latter is tied into the vehicle's CAN network, and therefore uses more signals to determine when and how much torque to apply to the Haldex clutch pack (and thus to what % the rear is tied to the front, i.e. 100% = 50/50 torque distribution). Thanks to this CAN integration, the GenII controller is slightly more proactive than its GenI counterpart.
MkV cars using the GenII controller can be upgraded with the GenII HPP. This unit has three programs in memory: stock, sport, and race. It can be fitted to the car without a switch, in which case it will be in by-default sport mode. This program applies more torque faster to the Haldex clutch pack than the stock program does, meaning the rear diff is tied to the front more quickly and to a higher degree. This, in turn, makes for less understeer and a more "planted" feeling.
The GenII HPP is an expensive piece, but it makes for significantly enhanced chassis behaviour. Imo, it is one of the best upgrades one can purchase for a MkV Quattro or 4-Motion car.
