Hi google for "BMW VIN checker" put the last 7 digits of your VIN in there and you will be able to see the build spec of your car. Bluetooth streaming and folding mirrors were optional extras on 2010-2011 cars AFAIK. As for fuel, there's those that do believe in the high performance diesel fuels and those that don't. Some swear by supermarket fuels. You pays your money and takes your choice, V Power nitro+ diesel is about 8p/litre pver standard Shell. I've run 5 series diesels for well over 100k and even running on VPN+ over a 2,200 mile period, I never saw a reduction in fuel consumption which made it value for money. Each to their own. JG
