I connected up my nano com this morning and managed to disable the horn when pressing the open button so then tried to level my suspension but alas it dropped completely. I did see on the nanocom that transport mode was enabled so I disabled that and pressed the write to eco button, but I am now unable to raise either of the rear airbags. I can hear the compressor make several clicks and when I checked the engine fuse box FL9 was blown. I swapped that for a new one and that did the same. Would a blown relay or seized compressor cause that? I did read there is a way to force the car out of transport mode via pressing a combination of buttons and the ignition switch (is that the case?) As I would like to try that first. If that doesn't work I will order the Schradar valve kit/compressor bypass kit you have previously recommended do I need the (4mm or 6mm version?) to get the bags up and the truck drivable and then work through the fault. Any advice would be appreciated.
