The story starts with a failure of the crack angle sensor on my 2000 4.6 HSE that required a tow to my local mechanic (on a tilt tray truck).
Three weeks later the mechanic had obtained the correct spare and fitted it. Once again the engine was operational, but now I had an issue with the air suspension.
The rear air bags pumped up correctly, but the front air bags would not.
I had an EASBuddy plug which I tried, but that didn't fix the problem.
I also tried running the engine with a door open to "charge" the air reservoir,but that didn't help either.
