If the compressor is running for long periods l would be inclined to check the air bags for potential leaks particularly in the highest setting. The compressor shouldn’t run very much at all. |

Thanks for the reply, the air bags are good no leaks.

Internal leak on the compressor is another possibility. |

AFAIK you can swop between them using the GAP IID tool. Also look at reconditioned ones? 2012 TDV8 Vogue (L322) |

Are you sure it’s the compressor rather than a bag or line with a weep?

This happened to me years ago on my 2006 4.4NA HSE Lux - it ran all the time because the internals were tired. Let's say that a normal piston stroke is 5 CC... I was maybe getting 2 CC per stroke because the rest was blowing past the worn nylon ring. I rebuilt it with a kit - that lasted maybe another 3 or 4 years and I ended up just replacing it. It was done at an Indie shop... so I am not sure what model I have now. That was 3 or 4 years ago and no issues. It is pricey - but if you are going to keep the truck, it is worth it. |

My 2007 4.2 SC suffered the same slow to rise messages. It turned out to be a pin hole in one of the air bags and a worn out Hitachi pump.
