A bleed sorted me for now. Fault never came back since then. In my case she had new hoses all around and pedal wasn’t right which only became apparent after a bleed. Ebay has some cheap ass pumps/modules on there too tho. From reading other posts here they give grief. So I’ll be back if it does. If anyone knows anything about programming or ways around it, it would be a huge help because I’ll be tackling with no know how otherwise and will cost me peace of mind to say the least haha.
