Hope this won't be too tricky. On 'hols'so finally a little time to sort things out. I've a few minor issues but going through them one at a time.

My rear left corner is resting down on its bump stops nearly. Tested the bag/system for leaks by jumping the xflow valve - it holds air fine. My basic code reader says the rear valve is open - so i guess its getting a signal and the system knows it needs air. The reader occasionally gives fault 'too much energy to fill rear left'. I also get the 'pressure static when filling' message a lot. Compressor is good.

I need to get my hands on the valve responsible - is the bag fill valve the one under the rear left arch or is it the one near the air reservoir? If I can check the valve operation I can move on to different possibilities.

Any other suggestions most welcome.
