Had a similar thing happened to me. Would only work for an hour or two then all the lights would come on the dash :-(
Good news is its a doddle to fit a new compressor and the one i got cost £300.
Thx
Ended up owning a L322 RR swapped the bald tyres for some General AT tyres last week so want to go play in the mud.
Any ideas or other RR people who can show me where to go ??
Thx
