So after a few hrs of idling my truck loses air
conditioning and heat functions and the temp in the nav shows 0.... it doesnt return to normal function till being driven in highway for approx 15min... and now with 7700km 180hrs 60 are idle hrs I now only get 690km to a tank had anyone else experiance these issues ??

 

That can't be with the 136l tank?

 

 

 

The engine temp is normal and yup with the 136l tank a ford tech has enformed me that these engines arnt made to idle and it will damage the motor. It apparently dose not idle high enough to burn off fluid therefore no air conditioning or heat I idle 10hrs or so at a time as I work out of my truck In the oil field I'm going to be contacting ford directly to ask them why they do not disclose this information to customers and sell them sub par vehicles that apparently only work like they should when driving .... pretty dissapointed in ford and the dealer that sold it to me knowing what I do for a living

 

 

Just curious how long you are idling?

 

It idles anywhere from 3 to 12hrs

 

This sounds pretty goofy. Today's engines can raise or lower idle speed at will via the PCM, and the engineers have programmed them to maintain the lowest possible idle speed for lowest emissions and fuel economy but will raise idle speed to charge the battery or achieve optimum engine temperature, or whatever other condition requires it. That "Ford tech" might have just been repeating urban legend or making things up on the fly. They get bored.

Seems like you have a problem that should be fixable.

 

I hope so it goes in Monday for diagnostics I'll update soon as they figure out whats wrong
