Hi Manuel
I am actually facing the same issue and engine behavior (EST A fault). it starts very well when cold and runs great until it is reaching the operational temperature, same as you.
Did you find out the reason behind ?
Please advise me, I must use full throttle to be able to start...
Hi !
I face exactly the same issue, starts perrfect in cold but after running it needs throtttle to start. Did you found out in your case where the issue was coming ?
