I've had my car back from the garage for a few months now and essentially I have a working car, though the key warning light on the dashboard is still on permanently and the Stop/Start button flashes red permanently (both obviously when the engine is running). When attempting to start the car, when depressing the clutch, the Start/Stop button and key light will sometimes go green but will usually be red. Either way, the car can be started normally and then both lights stay red. Sometimes the Start/Stop button needs to be pressed for a couple of seconds but I can always start the car.
In the end I changed both the Keyless Control and Steering Lock modules with second-hand ones from breakers. Additionally, I also had a clutch switch changed because allegedly the keyless control module remembers the clutch metrics from the original car. However, this hasn't resolved the light issues.
** So I could do with a decent auto-electrician, preferably in the Surrey area, that could diagnose and resolve the issue with the warning lights. Can anyone recommend one? **
I'm also thinking of selling the car and would get more and be easier to sell if the warning lights were not displaying.
Having said that, I'm quite happy to have turned a brick into a (fingers crossed) working car.
[On a separate issue, the cd/radio would sometimes cut out, along with random warning lights on the dashboard coming on. I therefore also had both door handle units replaced, at the same time as the above, with re-furbished units from a garage near Manchester. On early models the push button on the door handles for the keyless entry crack and let water in causing a short and the effect described above. Also, the car sometimes would not be able to be turned off. This has fixed the problem though I have had a single occurrence of the cd/radio cut out and dasboard lights, in the last few months]
