I have a 2011 Golf current 12,200 miles.
I was getting excellent mileage (all long trips, little city driving) around 48 to 50 and getting better all the time.
Then I did a long trip of 800 plus miles. On the way back I had a check engine light, yellow not flashing, I called the dealer and they said it was OK to drive. As I was getting near my 10,000 oil change, I decided to wait until then to to fix it. The nearest dealer is 60 miles away. My mileage dropped to 40 mpg. The dealer replaced the oxygen sensor.
I have been driving the car and getting around 43 mpg driving carefully (55 to 65). I called the dealer about the low mileage and am taking it in next week for them to check.
They said on the phone that the oxygen sensor had nothing to do with the mileage, is this correct?
They also said that 43 mpg is normal for the Golf.
I have the records for my mileage (real, not the car computer) and they show a 47 mpg average and a high tank of 49.1 mpg before the check engine light.
What other things should I be looking for on this problem?
When I go in to the dealer on January 5, what else should I ask about?
