How is the pneumatic lumbar powered?

[Cherrypd]

Is the pneumatic pump for the seat adjustments on my A207 powered by the Auxiliary battery or from the main battery. Neither seat works but there are no codes showing on the icarsoft. Just wondering the the aux battery (which I didn't know one existed until the other day) could be dead.

I would expect that the pump has failed.. or that the lines have become disconnected. Have you checked the fuse..

Yeah the fuse is good.

The pump will I think be in the boot, with a big lump of foam round it. I had the one out of my CLK and managed to strip it and refurb the comutator to remove the carbon burn ring. Seven years on and it still works fine.
