Hi all, I had problems with my front struts, they'd drop to the ground after a few hours so I ended up changing the pump and valve body. ( yes I inspected the struts for leaks and there weren't, used soap water method) I put new airmatic pump & valve body..but didnt change the relay, does it make a difference? The pump turns on but the car doesnt raise. The message appears on screen " Vehicle rising ". Once the pump stops it reads " Visit workshop ". I pulled out the fittings from top of the struts where the vacuum line goes and noticed there was no air coming out of the lines while the pump was running. What could cause that?? Is it possible because of the relay?? obviously the pump is working but the shocks arent getting supplied.
