This problem only seems to happen on cold mornings.

The following has been fitted to the car in order to try and rectify the problem.

New Battery

New Heater Plugs

New Heater Plug Timing Module

New Starter Motor

The problem is, if the car is left to stand overnight, then in the morning it will not fire up, it will turn over ok, if you jump the car from another car without the engine running, the outcome is still the same, but if you start the other car then it fires up straight away without waiting for the heater plugs. The battery is charging at 14.3volts when the car is running, once the car has been started, even for only minutes it will then start and run all day with no problems, it just seems that it never wants to start if it is left more than 8-10 hours, diesel is getting to the pump ok, and the heater plugs work as they were tested out of the car resting on the engine.

Renault have had this car in there garage 4 times and we have paid over £500 for work that made no differance, the car starts ok when the whether is warm ie during the summer months....it just does not like the cold. Any one got any ideas????????
