Had the rangy re-mapped today by that very nice man from Dynochip and whilst he was at it he got his super all dancing Diagnostic equipment out and gave the car the complete looking at, I do have further issues which will be put in another post.
we looked at the Air suspension and the tank is holding the pressure spot on and the compressor fills it spot on, so why its says Unable to hold reservoir pressure im not sure, seems the problem must be in the valve block with it sticking or something. just reluctant to have it replaced as the cost aint cheap if it aint going to solve problem is there a way to test the thing institute??
