I have taken it for a drive trying to make it go in to limp. Going slow, hard normal uphill, downhill. moving starts to hill starts. Can't get it to stop which normally would be great but these things do not fix themselves. I have looked at disconnecting everything but don't have the right pipes to go to right places. After I put in the plate before I put in the dawes and needle valves it was going in to limp straight away.
