Until now, I've been extermemly happy with my June 02 audi A2 - now just out of warranty. The anti-roll bar is corroded. Has anyone else encountered this? it was off the road undergoing crash repairs for 5 months (I was stationary and rammed from behind! )The car was rebuilt at Wayside and has just under 40k on clock. but corrosion?! Anyone got any thoughts on this?
