I remember also a suspension failure and a wheel hub that broke. The only mistake I know of was in rally GB when it was inevitably pissing down and the road was slick but he wasn't the only one. Sainz and Martin went off at the same spot.
Imo Loeb didnt won 2003 season becose of team orders which didnt let him fight with solberg becose citroen needed team points and they choosed not to risk.
