@fab5freddy thanks pleased with my effort@99hagued Not sure on difference, as did multiple tasks (rfd, rs4 valve, loba hpfp). brought a cheap blaster of eBay for £10 that fitted on a compressor line and adapted the end with some copper pipe also adapted a silicone hose:@Pudding obviously can see my attempt at replicating the BMW kit. The BMW does fit our inlet to but are about £90 for the atttachment but not readily available in the U.K. Someone in America has 3D printed versions for about £50
