Well, nearly a year before seeing that shiny SES light on the dash but nothing lasts forever I guess. Today popped up a P1419 code for the SAP system.
I took the engine bay DME/EGS cover off and bypassed the salmon relay and the SAP pump works just fine. Nice and quiet and pulling air past the MAF2. I took the SAP valve off the cylinder head and cleaned it really good with brake cleaner but honestly, it was pretty clean. A little soot on the head side but still a great opening and the SAP pump side was very clean. Not expecting that to be my issue.
Not much I can do until the morning to see if the pump runs at start-up but I think I am down to either the SAP relay is faulty or the MAF2 has failed. Both are not that old, maybe 5 years.
Any suggestions guys?
