yes, there is someone who went in for some unrelated work and had their warranty voided when the dealer found evidence of Procede installed. The person's HPFP went bad a couple of weeks later and he's screwed because BMW will not fix it under warranty. A BMW service tech looked up his VIN and the fact the warranty is voided is on electronic record for any dealer and BMW to see. There are a couple of threads on it.
