All,

This is actually for an 07 Jetta TDI (BXE), but seeing as nobody posts in the Jetta section, I'll post here and hope for some answers!

OK, here's the list of symptoms the car is exhibiting. If anyone can offer any kind of suggestion as to the cause, I'd be very grateful;

Heavy rubbing noise when turning at slow speeds (on car parks, coming out of junctions etc).
Intermittent loss of drive when cornering - split second shunt or feeling like the brakes are being applied. No abnormal noises.
Intermittent loss of drive when driving straight over undulations or speed humps - as above, split second shunt or feeling like the brakes are being applied. No abnormal noises. Repeated undulations seem to affect the car's momentum.
Intermittent shunting when applying accelerator after gear change (sometimes there is also a light 'clanking' noise). Also can be noticed when on/off the accelerator when in slow moving traffic.
Sometimes drives like the tyres are 50p pieces - feels jerky/rough and feels like a lack of torque.
Extremely twitchy handling - drifting in winds or drafts from other vehicles, hard to keep in a straight line especially at motorway speeds. Four wheel alignment and balancing have been carried out.

Can anyone think of what might be causing all this? It's something that's getting steadily worse, and the shunting/loss of drive happening once or twice a day. I don't know if this is a suspension or transmission problem?
