Hi Martin, how are you getting on with using gridserve now? I have recently had my car serviced/software updated and now no longer works at gridserve (I travel from Glasgow to Barnsley and normally use the Weatherby Services Chargers/Scotch Corner Services). Do you think it is more than the cable being stretched? I have mad the trip multiple times with no issues however seems odd after a software update/service (literally following day) it no longer works with same 011 error message.
