I've got a 56 plate MkV and after almost 10 years of near-faultless motoring, it looks like my stock Haldex unit has gone wonky. My ESP light first came on after a particularly long (and wet/salty) drive and soon afterwards, started coming on regularly after about 15-20 miles or 30 mins of driving. The light clears if I cycle the ignition but it's only a few seconds before it's back.
My local garage took a look and gave me a printout of the results. It was coming up with an 01324 (J492) under ABS and both a 00003 and an 02248 under AWD. He reckoned it was the controller itself and couldn't be anything else so I started looking into what I could do about it.
Being chronically short of readies these days and hovering on the brink of having to sell my beloved motor, I decided to send it off to Auto Fault Finder in Congleton for a clean-up. Apparently it wasn't that badly corroded but nevertheless, within 40 miles of being refitted it's back doing the same thing (at least the J492 anyway - didn't see a full readout the second time) so either it's an unfixable Haldex box or it's something else wrong with the car altogether (or even worse - both).
Before I go down the route of shelling out for a completely new controller, can anyone think of anything else that might cause this? I'll be sick as a parrot if I fork out £1000 for a new one only to find it's made diddly squat difference.
Also, do any of you lovely people out there have a working stock controller, possibly one you don't need anymore 'cos you replaced it with one of those fancy blue numbers? If so, do you want a new best friend?
Cheers in advance for any advice/sympathy/charity that might be forthcoming
