Drove the car home from service it stalled upon start up. Started, idle surged, dropped, then stalled. Started again, idled fine. drove home. Noticed idle surge and drop.
I am still working with the dealer in Houston to resolve and get satisfaction. I have now put ~80 miles on the car since it was delivered.
In addition to the previous service completed last week:
-BMW fuel filter
-BMW inline fuel filter
-BMW fuel pump.
Yesterday I had a MotorVac CarbonClean Service performed. Just as another option to continue to isolate the issue.
I went ahead and had the thermostat replaced. I cannot hold that against the dealer.
Had the a computer scan done on the HPFP's. Reading at ~400-450 PSI on each. Should be 1,740, or 120 bar.
Notified the dealer that we needed to focus on the HPFP's. No response from dealer.
I will check some of the other items: fuel pressure sensor, crank sensor, etc.
Everyone please continue to provide input. It is greatly appreciated.
