Have had a go at curing some of my EAS problems but have not got far. The back end pumps up to max pressure and extension, whereas the fronts are getting no air at all which has been the case for a few weeks. The RSW diagnostic often says the exhaust valve has stuck so that has been replaced, at the same time I renewed the front bags as one was leaking slightly. Even when I depressurise the system the backs stay pumped up. I let all the air out the backs in the hope that everything would reset, but still nothing to the fronts, everything to the rear. Any ideas?
