Update time.................
Went to yet another garage today, although not a "VW specialist". The guy said it's definitely not the CV joints (3rd mechanic in a row), and instead thought something might be rubbing.....He had a look and reckons that the front left wheel is rubbing on the gearbox when turning (there is a big rub mark on gearbox and inner wing), so I guess I will have to get some smaller wheels...........At the moment, it's lowered on 17s, which according to this guy is the root of my problems....In my defence, it's how I bought the car, only had it a couple of months.
Should I look out for 14s or 15s? I was thinking that 14s would be too small but keep seeing those P Slots on ebay......
