I think you're already along the right lines, i.e. air leak somewhere. A previous D3 I owned had the same fault and symptoms caused by a pin hole in the reservoir (which I found almost by accident). If the compressor is functioning correctly, then you're leaking air somewhere. I think all you can do is follow each line through from the compressor. I assume the compressor isn't running excessively? Also, one side dropping, regardless of incline, etc. could well indicate where the problem is.

Did you recalibrate after fitting the new height sensor? 2012 TDV8 Vogue (L322) |

If i clear the fault code it can move up a down in all 3 positions but the code quickly comes back and then it’s stuck.

Have you looked at the valve block ? Checked to see if that’s leaking or what about getting a rebuild kit for all valve blocks ,I was having similar issues turned out it was the front valve block seals ….kit is only £18-20 .worth a go |

Thanks for the advice, where did you purchase the rebuild kit for the valve blocks? I’ll definitely give it a go. Thanks |

Is the air leak at all 3 heights or only one? 2012 TDV8 Vogue (L322) |

It’s stuck in normal ride height only, and if there is a leak then its slow because it can be days before any drop (if there is any) |

What about the big discharge of air - this is not normal as the only vent is on the pump. The air springs usual develop a leak on the fold where the rubber gets deformed the most and this can be worse at different hight settings. 2012 TDV8 Vogue (L322) |

I can’t see or hear any leaks from the rear bags the front bags were replaced about 8 months ago as a pair. I’ve used the old washing up liquid solution and sprayed it and can’t see any bubbles so I’m stumped.
