I'll bare that in mind mate :smile3:i ended up getting a launch pro3 scanner to sort this out , It can read every part of the car and even actuate individual parts on the abs/hvac systems . Great bit of kit works all makes and models up to 2016
if anyone in Glasgow is stuck and needing a scan let me know and ill help them out , can do regens on dervs too.
ps all four wss resistance should 1.5k (or there abouts) .Also when you turn the key there is .5v pulse sent to all 4 connectors to check for open cicuit .
hope this help someone .
