check the cable that goes to your temp sensor it might be open somewhere. it earths against the body and show high temp even if cold.

Was it a dodgy garage?

Glow plugs are really essential for our climate.

after spending 5 minutes trying to decipher what you wrote, i came to the conclusion that the garage might not have filled your tank with diesel.

seriously though, if you cant be bothered to articulate yourself clearly when asking a question, how do you expect people to take you seriously enough to try and help you?

and temp gauge telling me there is a closed circuit somewhere even if temp gauge earth should still start so im asking if anyone has experienced this problem and can help
