wont be the relay as when I bridge the pins at the EAS ECU multiplug it’s makes the compressor run.

Ok. So. Hmmmmm head scratching. Obviously something somewhere is faulty which will not allow the system to reset. So it can’t be the compressor because it doesn’t even get fired up by the system long enough for it to cause a fault. Plus wouldn’t I get a fault code for the compressor? I can...

The compressor was the first thing i rebuilt. it will not be the compressor. There is a fault which is stopping the system from firing up. So the compressor doesnt even get a chance to run.

Its the first time its done this, normally it connects fine but EAS still doesnt clear faults. I think im now at the point where i need to start changing everything as no-one seems to have any ideas what it could be.

Right. Plugged in all comms this morning. was havoc trying to read modules. Kept saying ECU offline, then it would say k bus offline! Had to open comms a lot of times to try and read the modules. I can’t see anywhere in all comms to check the pressure in the reservoir?

The car is currently pumped up, it goes down drivers side a few cm over about a week of not being used. I tried clearing codes when it was level and still no luck.

Yes, compressor runs when ignition switched on. I can also manually bridge the pins on the EAS ECU multi plugs and pump up each corner using the compressor

The light on the dash comes on and goes off so quick it doesn’t have time to move, 3 years I’ve been fighting it to get it working

will switch on all comms in the morning and find out :)

the fault codes are front right and left valve fault plus a front valves supply fault. So I wonder what the supply means in the code.

when I clear them using All comms, the lights come up on dash for a second and go off. Faults are still there. Ive tonight tried a different main valve block to no effect. When it says supply, is it talking about voltage or air?

sorry but meaning?

I’m still chasing this fault if anyone has any suggestions? Are the main suspension valve blocks a common fault?

Hopefully, just got to spend some time taking it all apart again

And your the winner LOL. Just found the magnet in the old wheel. Covered by the grime so unseen!
