HPA Motorsports Gen.4 Haldex Controller for VW MkVI Golf R/Audi TT-RS

[VAD@HPA]

The newest generation of 4Motion equipped cars use Haldex's fourth generation of AWD systems. The Gen.4 Race Controller takes into account the TPS signal more so than the OEM software and therefore can proactively begin applying power to the RWD clutch packs before wheel spin begins, and as power is increased, more power lock occurs in the RWD unit until full lock is achieved.

This product offers the following benefits:

• increases torque transmission at acceleration
• provides consistent performance with increased over-steer
• torque-transmission is influenced by how quickly you depress the accelerator
• transmits torque before the engine delivers torque
• at greater speeds, the torque will decrease enabling less over-steer and safer driving properties

HPA Motorsports is proud to exclusively offer our "Stealth" Gen.4 Sport Haldex controller. Identical in appearance to your stock controller, you can now enjoy all the benefits of this performance component without jeopardizing your powertrain warranty. The Stealth controller is undetectable by your dealership; both visually as well as through a scan of your Haldex AWD drive system.



By default, the controller is designed to be in Race mode which completely transforms the handling characteristics of your AWD car by providing faster reaction time to vehicle inputs in the AWD communication system, increasing torque transfer to the rear axle, and giving more rear wheel bias.

With the installation of a specially engineered wiring harness and switch, or wireless receiver with remote, you can have instant access to all three of the programs built in to the controller; Stock, Race, and Eco.

As an enthusiastic driver you may not find yourself using Stock mode very often, but it will come in useful when loaning your car to an inexperienced driver, or when you are driving in slippery conditions and want to engage the conservative safety parameters set out by the factory.

Eco mode was developed for increased fuel efficiency. Its purpose is to reduce the torque transfer from front to rear during normal highway driving (coasting), but will immediately engage the system if a wheel starts to slip to prevent decreased traction situations. This mode is recommended to be used when AWD drive is not a high priority.

Fitted mine 10 days ago

Fitted switch but left cable under rear seat, (switch fits perfectly in the cutout around the sender

There is a drivabilty difference, hard cornering pulls around a lot cleaner with less understeer drag.
Taking off hard front tire rotation is at a minimum compared to standard.

Thank you for your orders!

Do you still have these race-only units? Is this something you'll always offer? I'd like one for my RS, but I don't see it on your site.

Send me an e-mail and I will check inventory on these units at Haldex in the second week of January when we re-open. If we can still get more, I will honor the price I quoted.

TTRS, using the remote, can I tell what mode I'm running in. In other words, does the remote indicate what mode it's on? Is this system undetectable unless someone sees wireless receiver or switch?

The remote is just a series of buttons, there is no indicator showing the mode you are in. The controller is electronically undetectable (via diagnostic tools), although the wireless receiver will be visable under the car.

[VAD@HPA]

All Haldex configurations in stock and ready to ship.

[sentari]

True, but there are beeps the seem to come from the receiver. Is there anything to know about these beeps (seems like 1 beep = regulars, 2 beeps = sport, 3 beeps = race)? It seems it would be hard to determine if the switching is not actually working.

Honestly I've just kept mine in Race mode.

Is there any potential for excessive wear on the Haldex by being in race mode all the time?

We have had customers who run consistently in race mode with no issues reported. Maybe a slight decrease in fuel economy, thats about it.

[VAD@HPA]

Big props to HPA.

Really friendly, solid customer service both on this (Haldex) occasion and when I purchased the core interlock mount a few months ago. They really are just a phone call away.

Appreciate the help guys and can't wait to reap the benefits. Thanks again.

i would imagine this is a must have mod for TT-RS owners in my opinion. i'm dying for a TT-RS, and if i do get one, surely this and an ecu tune will be the only things i do to it. i can't imagine how much the front tires are being overworked on a car like this with this type of power. and its quite disappointing that audi didnt adjust the awd system for a rear bias for a car of this caliber with an RS badge. but regardless, if this haldex controller can't be noticed visually by the dealer and can't be found by them scanning the awd system, then it's a no brainer. i would like to know however how much of a decrease in fuel efficiency we're talking about here, and also, why we can't make it completely rear biased. for example, in the race mode dyno graph, i feel like if the front wheel power and rear wheel power graph lines were switched, it would make for a perfect ratio. just a little more rear wheel than front wheel as opposed to a little more front wheel than rear wheel (as it is now in race mode) would be ideal..

[canuckttrs]

What are the numbers wrt torque to wheels compared to oem?

ignore the sport mode, which i don't believe is available for the TT-RS. instead you would have an ECO mode. honestly, i wouldn't even get the switchable haldex, i'd just get the one thats in race mode permanently. it seems best all around, for performance, and for the snow as well. it just offers the most traction. but still, i'd rather more of a rear bias..

[Black BeauTTy]

I have to be honest, I just don't see the point in monkeying around with this. The car feels like it is about to pull a wheelie when launched hard as it is.

The TT-RS automatically moves all the way in to a "Race" mode depending on detected conditions / wheel slip, so it's not obvious to me how needed this really is.

On the track, what I really needed was a way to reduce understeer even when not applying power. I didn't get the feeling that I had a traction limitation for putting power down.

im not a TT-RS owner, so i haven't even driven the car. you own the car, and if you say this isn't necessary, then i'll agree with you. realistically, i would never track the car anyway, i would just take highway ramps fast and corners fast, nothing too crazy, so i guess it wouldn't be necessary for me. but just the fact that this car is 85% front wheel biased regularly just seems stupid to me. i know it adapts and adjusts and can send as much 100% to the rear wheels, but it will only do that once your front wheels have completely lost traction, which would mean you're already understeering, which would be annoying since you shouldn't really ever understeer in an awd performance car because it should be rear biased..

I'm not saying it wouldn't be noticeable, I just question how "needed" it is.

Putting most of the power to the front wheels should help reduce driveline loss (maximizing power and economy in high traction situations).

100% power to the rear wheels can only happen when the Haldex is locked and the front wheels have zero traction.

do you ever feel like the car is front wheel biased on the road? like when taking hard corners, driving aggresively, maybe taking a long highway ramp? do you ever feel like, "man, these front tires are being over worked, i wish it was more rear biased and tail happy!" ??

If the RS is the same sort of Haldex as the 3.2 then if you don't own one or have experienced the performance RACE mode then just stop talking and start listening. The performance Haldex is (in the end) an in expensive mod to your AWD that will transform the car into the beast that it was meant to be in the first place -- except for Audi likes to play safe out of the box. I have a remote, but really, if it were designed to be in Race mode all the time---that would be just fine with me. It's still got plenty of AWD to get through the snow and such, but does not pusee foot around like stock. Plus, the MPG is about the same. My calculations have not seen any statistical difference. People pay like $1500 but for "race" OE exhaust systems when you would be better off just turning your radio down a bit! So give it a go and get on board with a real Haldex.

[canuckttrs]

Pm me for prices on a TTRS.

[JohnLZ7W]

Keep in mind the RS already has much more aggressive tuning for the haldex than the 3.2. It already starts transmitting power based on throttle input like the blue controller does.

[YYC Dubber]

Would be great to here from RS owners who have made the switch and their impressions
