Td5/Series II Rear Air Suspension - VALVE BLOCK

Morning all,

Does anyone know if it is possible to buy just a replacement valve block for the SLS and not the whole compressor? Can't find one anywhere but I am now 90% sure that my sagging rear-end is due to a leaky/faulty valve block, and not leaky bags, or faulty height sensors.

Can get a whole compressor fo around £205 but was hoping to just replace the valves and save some cash.

Cheers
James

hi have just started with the same problem, not sure if height sensor i dont think the air bag is leaking so may be compressor valves.
let me know .

thanks

have you done a soapy water test on it???

try pulling out the pipes and replacing the little 'O rings' first, mashed one of mine up and it started leaking..

Tried to get under it today to soap test the valve block - got the cover off easily enough but can't really access anything

Reckon I'll have to take the whole compressor off or just get it up on a ramp??

no you wont need to

fixed a new compressor recently to mine.. there are a couple of 10mm bolts holding it onto some lugs on the chassis. take out the bolts and there sould be enough slack in the pipes and cables to drop it down.

put a house brick or something underneath to support it then test it from there.

good luck!

remember all the doors, including the boot need to be shut or the compressor wont activate.

Had similar probs with mine a couple of months back. Enquiries to Dingocroft suggested that they may be able to source valves separately to compressor, but after dismantling to check out the prob - and yes, you can just drop the whole box off the side of the chassis easily enough - I found that one of the valve bodies had simply come unclipped from its actuator. Just pushing it all back together and making sure the clip locked home cured the problem completely. Cost nothing, took 20 minutes to do.
