The BMW 6 Series builds on BMW's sporty heritage with aggressive lines and an incredible motor to back the design up. Available in coupe and convertible trims with a standard 4.8 liter engine producing 360 horsepower and 360 lb-ft of torque, the 6-series is a popular choice that exceeds expectations. |

"Increased Emissions" and running a bit rough.
I've searched as much as I can, but can't find my exact issue. I got the "Increased Emissions" warning about a month and a half ago on my 645ci. I ran a scan on it with my generic scanner and it gave me the "Coolant Below Normal Temp/Thermostat" message.
So I replaced the thermostat and reset the light. Two weeks later it comes back on, same thing, so I try replacing both of the other temp sensors on the return pipe and water pump. This morning the light came back on. Addtionally to this, since i got the car ~3 months ago...the car runs a little rough at idle and shakes a bit. I notice some slight surging while cruising at a constant speed too. So, I'm wondering if I have a coil or other issue instead, but for some reason I'm getting the low coolant temp message on my non-bmw specific scanner? Any help would be really appreciated! Oh, the car has 88K on it.
