gas milage for a 335
Hi,
I purchased a 2009 335 about a month ago. I then installed the BMW Performance exhaust system. I noticed that it takes a long time for the car to warm up and the Gas milage is really bad around 15 l/100Km combined. I am thinking the oxygen sensor what not installed properly when they changed the muffler. Any ideas?

Did you install the exhaust or have a shop do it?
Do you know exactly what components were replaced? If they only replaced the muffler, they would not have touched the O2 sensor. I think you're probably right, if the sensor is messed up, you'd get bad mileage and it would take a while to warm up. |
