Haldex upgrade
Hi all,
As some may have seen, I just took delivery of a new Passat V6 4Motion wagon on Monday 18th February. See thread here now with photos:

On Friday, I had a generation 2 Haldex controller installed for the front/rear torque split.

It can be set to 3 modes;
1) factory setting - setting is the same as what comes originally with the car.
2) Sports mode - this setting pre-empts throttle input when going around corners and applies more power to the rear for a more neutral handling and much less understeer.
3) Track mode - as the name implies, this is basically for track work where the torque is split 50/50 all the time except when required to be otherwise by the inputs from the car and then torque is split where required.
Most have it set to Sports mode as I also decided to have it set at. You can have a 3 position rotary switch installed so you can select the mode you would like to use, but this was an extra $400 for the loom plus installation.
I also had a polyurethane bush installed on the lower engine mount. This tightens up the rocking motion of the motor and makes the gear changes seemless.
The Haldex works very well. The standard set-up of the car from factory does have a little bit of understeer when pushed hard, but the Haldex addresses this situation very well giving a very neutral balance to the handling, although when pushed hard may even exhibit some oversteer, especially when the power is applied through and exiting a corner.
As the Haldex was installed at the Sydney agent of APR at Mona Vale, I took it for a run through Kur-ing-gai National Park from Mona Vale to Terry Hills through some very nice windy bits and now the balance is excellent. Using the Tiptronic was a blast and the car went like a dream and goes like a scalded cat! Maybe a little soft on the front, but overall a real thrill to drive. This car rocks!!
The Haldex costs $1699 installed and it is worth every penny, IMO.
