My 745i started showing emissions service engine message but runs just as good as before. The only message that came up on the scanner is 279 p or something with the thermostat. My question is does the thermostant affect emissions??

Code P0279 relates to :

- Dirty Fuel Injector 7
- Faulty Fuel Injector 7
- Plugged Fuel Injector 7
- Fuel injector 7 harness is open or shorted
- Fuel injector 7 circuit poor electrical connection

So if your getting that code i'd look at Fuel Injector 7.....:)
