Can someone do me a massive favour? My s3 has been in the garage for a week while they try and work out why my haldex isn't working. They've narrowed it down to two possible things. It's either the haldex ecu or the wiring loom from the front wheel speed sensor. I want to avoid throwing money down the pan by isolating the issue. Does anyone local to Kingston have a haldex issue that is known to be working that I can borrow for 48hrs?!
