Haldex Controller Update: Blue – Orange – Silver Controllers

Hi Guys,

I wrote to Nik at HPA today. Is asked him to explain the difference between the Blue Haldex controller and theirs. (Theirs was an Orange Haldex Controller and now it’s silver; no paint at all).

Blue Haldex Performance Controller

Blue Haldex Performance Controller available at the TT Shop for around 900$

So here’s Nik answer:

“In the past we had sold both the blue controller as well as our competition controller. We elected to stop selling the blue controller as many of our customers ended up exchanging the blue controller for the competition controller. I haven’t even had one inquiry for the blue controller in the past two years!

The main difference between them is that the competition controller will not stop transferring torque to the rear wheels when you lift off the throttle.

It will enable you to achieve slight oversteer should you desire and it will not have to “re-load” torque to the rear when you depress the accelerator pedal again. 

I have driven cars equipped with the OE, blue sport, and competition controllers. I don’t believe there is enough value in the blue controller for the money when you consider the minimal difference between it and the OE controller.

Having had experience with all three units, if I were to spend nearly $1000 on a replacement, I would have to go straight to the competition controller.”

I will be buying HPA’s controller soon. I am also planning on creating a video of my car spinning before and after the controller change. Hopefully, we should see only the front wheels engaged before and the rear and front engaged with the new controller. Keep watching!

    Hola andré, para el controlador naranja, es necesario colocar radiador de aceite en el haldex,?, no es muy exigente para los embragues del haldex?. el uso de mi tt mk1 es solo para calle. muchas gracias.
    Tu blog es muy interesante, muy instructivo, gracias por ello. he hecho un enlace en Audi Forum Argentina, para el que lo quiera leer.

    Andre- I am considering the competition controller. Did you install it, and if so, what has the result been? Have you changed the Haldex system oil more frequently? Have you noticed any increase to either driveline noise or vibration?

    • Hi MaTT,

      Yes, it’s installed on my TT. I tried bot the street and race track.
      I cannot say, like others do, that I have seen a big difference in performance. There is definitively a noticable change and anyone serious about TT performance will make the change.
      No, I did not see any increase of driveline noise or vibration!
