hi all, long time since last post as i put the supercharger away for a couple of years. got a question as i feel the pump is cutting in more than it should, so i will explain what's been going on . so picked it up from workshop and came up with parkbreak fault so put the gap tool in and came up with epb motor over heat so dropped subframe removerd epb module and rebuilt it put it back and all working so put it all back together next morning went in to the barn and the l322 was down on the rear bump stops front was fine so a leak some wear on the back only so went around with the soapy water and found the voss valves leaking removed both bags fitted new valves tested in a bucket hole bag for leakes all good wile i was in thear i replaced all air pipes from the rear from rear valve to bags with new pipes . also replaced all the o O-rings in the rear valve . so left it over the night and next morning she had not moved well 3 mm . But to me the compressor is coming in and out a bit to much . as if i have a leak but the front and back is not lowering i am sure someone can put some light on this and help. Many thanks new vehicle purchase

hi had similar problem when i had l322 ,there is a valve block in the the boot (known as centre block ) could be the seals in there as well .i ended up rebuilding my rear valve block twice in the end problem sorted after that .could also be your air compressor or the air lines coming out of it

thanks will 308f i have a seal kit for that valve block so i will remove it and do them . i did replace compressor back in 22, and it has not had a lot of use in that time so will do seal kit first i thourght it mite be the solenoid that sits on that valve unit. I'm not sure what that does if anyone can explain that for me new vehicle purchase
