Rear tale gate control module needed to be replaced as this was causing problems with the central computer and causing the airbag warning to be displayed.
The car is generally very good apart from the lack of economy.
Previously owned a 330d Sport and managed to get 42mpg regularly. When I decided to look at changing my car for a larger booted one, due to the arrival of a baby, I thought I would stay with the manufacturer I have trusted for my past 3 vehicles.
Originally the car was fantastic I was getting 47mpg until it went in for the warranty work to be carried out for replacing the boot opening module. BMW updated all the software in the car, which must have also updated the ECU mapping because now I struggle to return 37mpg. BMW claim that there is nothing wrong with the car.
It has seriously tainted my view of the blue and white propeller.
Silly Question, but have you taken the car back to the dealer and explain this to them? Have them explain exactly what they did and how it could effect MpG.
I believe he has, and "the response was the car is perfectly fine and nothing was wrong" as he stated!
As with a doctor, get a second opinion. The line: "That's the way it's supposed to be," should be gold plated in every dealership. They use it every time they don't want to fix a service department error. Take it to a hostile dealership and you'll find them happy to repair whatever the first one mucked up, with plenty of complaints about "those other dealers."
