Just to add Coffeekid - your dealer will almost certainly refer this back to Caterham HQ. If so, don't take any rubbish from them. After mine went back to Caterham for the fourth time, I had HRH the Chief Executive on the phone telling me the fault did not exist, no other car had had the problem and their technician could not replicate the fault. I pointed out that I had an email from their tech guy saying it had cut out on him on a test drive, but the ChX dismissed that fact and the best they offered (remember this was under warranty) was to sell it for me - complete with fault - on commission!!!!!!!!!!!!!!!
