Hi all

So the other day I thought the front left air bag had gone but after using my gap iid tool, I've figured that is not the case as I've been able too inflate it too around the 90 mark and it holds the pressure. Oddly if I put it into off road mode it holds the air. I managed about 3 mile driving like this before I got above 30mph but then it slowly goes back to normal where you can hear the air compressor working and the front left keeps deflating down to the access mode then it comes up again.

I've had a look at the faults and this seems too be one that remains which is the ride level control module.

Would you start of by replacing that? My thought process is, get one of ebay and if that fixes the issue then I'll just order a brand new one so it's done then and sell the 2nd hand one too another member.
