I've had my battery checked (it's OK) and was persuaded to have my glow plugs and harness replaced (not cheap) but the problem remains. My dealer says I can book the car in to have the issue diagnosed but I am reluctant because they will not see the problem if the engine is not freezing and the exercise will simply be a raid on my wallet.
I suspect that there is a temperature sensor that determines how long the glow plugs are on for. Can anyone confirm this? If so, where is it and is there an easy way of testing it?

Thanks in advance.
