The car only has air on the back.

Passenger side rear was down after about 24 hours when not driven. Drivers side down a bit, but assumed this mainly due to the other side dropping.

The Air Bag on one side didn't look too good so put a new one on.



Started the car, it went up (as it always did do) - used Star to do automatic levelling - but was not level, about an inch lower on the side with the new bag on.

24 hours later passenger side rear is back down again - so problem same as before.


Have sprayed water on the 3 port valve in the engine bay - can't see an obvious leak, are there any other obvious points where the pipe might fail, is one other possibility the 3 port valve block could be leaking internally perhaps....

When I plugged in star a second time, the error was 5501 and suggested checking for air leaks...

Any advice would be most helpful...

Check lines end to end. On some cars they go over the rear subframe and can wear through.

im currently having issues with the air sus set up on my disco 3 , you have to check the lines extremely thoroughly pal as LK says they can wear through easily over time and you should use soapy water really , it gives better results
