So i cannot get rid of this fault code on my S3:

Address 22 -------------------------------------------------------

Controller: 02D 900 554 B

Component: HALDEX LSC ECC 0006

1 Fault Found:

65535 - Internal Control Module Memory Error

And have decided to bite the bullet and get the performance upgrade, getting fitted at the TT shop at a deal that undercuts AMD by a huge anount!! grin.gif

Now before i go and get this done (booked in, in 2 weeks) is there anything else it could be? would you recomend a 2nd hand OE Haldex controller? Will i REALLY notice the difference?

Thanks, Rav

Had HPP fitted earlier this year and tbh, not a lot of difference from standard imo.

Really thing you need to be caning it (or on a trackday) in order to exploit the full benefit of the little blue box of tricks.

Try and clear the fault code and invest in some uprated ARBs instead if you want to feel a difference in terms of handling 169144-ok.gif

A generous friend bought it for me as a b/day present grin.gif

Honestly, can't say that I've noticed a great deal of difference. Think that it requires your driving style to be 'enthusiastic' in order to feel the real benefits of the HPP.

Wonder if the fault would clear if you disconected the Haldex controller or it's fuse, started/stopped the engine and then reconnected things?
