Answer
It sounds like the compressor relay (#20) failed and kept the compressor running.  This over-pressurized the system and inflated the bags through leaky valves in the block.  Replacing relay 20 is the right direction, but you have a hard fault which will need to be cleared by someone with LR diagnostics.  Does not need to be the main dealer.
