Had a VAGCOM check on my 2001 S3 at a local garage. Garage came back and said that, amongst other things, the "Haldex controller is faulty and needs replacing". My heart sank a bit when I was told that this equates to approx £750 inc VAT fitted for a new one. So I ran a quick check through some threads on here and found that if I put my car on a ramp, start it, engage 1st gear (or any gear) and accelerate then all 4 wheels should rotate. I did this and all 4 wheels did indeed rotate. Am I missing something or is the Haldex controller working completely fine? Additionally, I checked my Vagcom report for a "Haldex controller is faulty" code and found this code. "65535 - Internal Control Module Memory Error" Is this the Haldex Controller or somehting else? (searches seem to suggest either controller or airbags. Any help gratefully received as I dont want to spend £750 if the Haldex is fine.
