Thanks for your answer
the car starts normally when the engine is cold.
So I assuming that the glow plugs are working
Usually it is when i have driven somewhere and i come back say 30 - 45 minutes later that the car cranks over and over without starting up.
last time I cooled the engine down by hosing it with cold water and then it started. Obviously i cant keep on doing that
Thats why i thought about using the easy start fluid for next time when this happens.
I have bought some injector cleaning fluid that you put in the fuel tank.
Is that what you mean by cleaning the injectors?
I will change the fuel filter and egr valve to see if this makes a difference as well.
To replace the injectors is an extremely expensive process
I am lead to believe.
Thats why I am trying to find an alternative solution for the odd occasion when i need to start the car.
Do you have any diagrams which can help me locating the EGR valve?
