Hi
Is it possible to jump the ECH to manually try the air compressor ?
There is a vid on the net, where a chap jumps the pump and inflates his air bags, I can't really tell what pins he is jumping...

Can anyone advise?

To recap, I've checked the boot fuses which are 0k.
The pump seems to make a noise for 30 seconds then stops with no lift of the rear suspension.

Is this likely to be the ECH unit ?

Are there any other fuses or relays that I need to check...

Really need help on this as gotta get to work on Saturday

Cheers

Gary
