Did the Haldex pump fail?
Yep, pump failed. The filter was clogged and caused starvation. I probably should have had it looked at when I first noticed it, but I just thought it's winter and front tyres worn. It started to happen like many others not long after having it serviced.
VW were terrible to deal with. Refused to update software which was possible fix. Just wanted to charge to scan. Showed fault and had unit replaced and my mechanic had 2 days of issues with VW to get the updated software installed.
I totally love my car and way it drives but VW service turned me off. I am very unlikely to get another VW it's Audi as prefer service, sedan and better deals in Australia. Wife's on second s3 sedan and tough to find anything that comes close to swap to. Have 18 months til lease up so plenty of time. By then the a35 out, new 1series and mk8. So great time to update.
