Hello trucker, I hope you can help me !!! With our MAN 14.232 with rear air suspension it spins at the moment totally. First the large solenoid valve block was leaking over the rear axle. We have sealed it, is now also tight. Air he no longer loses. Can be lifted on switch position but also lifting but also not on switch position stop stop, that is, you can not stop at stop lifting. The same game with switch position sinks. i Driving position on the driver’s side further down than on the passenger side. We have already made the air spring valve on the passenger side and adjusted the bar from the air spring valve. However, nothing changes. He drives on the driver side almost completely again at driving position. We have already installed a new switch. The cables also have all the passage, so no cable break or so !! We have also separately attached 24V to the solenoid valve block, then lifts he and lowers it, that actually means that the relays work, very funny. Thanks in advance !!!
