Question
hi i have had my rr 1996 hse for 6mths no problems, i was driving and back right started getting lower after 1 min eas slow 35mph came up any way had it reset then did it again next day, back right drops, read ecu says front left valve stuck closed, i have had ne valve 4 new springs compressor and lines checked, had reset 1 day later did again back right drops down then goes to hard fault reads front let valve stuck closed? any ideals im going crazy and i have 24" wheels when it drops to bump stops this is resting on tyres and has made alot of mess, please help thanks

Answer
Sorry for the slow response.  With 24" rims you should add spacers to your bumpstops to prevent rubbing.  

The compressor may need rebuilt, they can put out the right pressure but pump too slow to compensate for leaks, the block is also likely leaking causing the majority of the problems.  the "front left stuck closed" is sometimes cause by the right rear leaking down.
