If he has no luck ill tell him about you having similar problems and to get in contact with Renault in chatham, kent. It really needs sorting.
All i get fed is "never heard of one going before" driving me mad.
Did you find the car pulling asif the tracking is out sometimes but then other times itll track straight? It feels like its wandering constantly. It certainly doesnt feel like the car is did 2500 miles around Europe in. I wouldnt even entertain the idea of the nurburgring again with the way the car feels atm!
Bet your car feels completely different now!
