hi guys

i think there must be something wrong with my car. ive got a 2005 525d auto, and i get about 24.9mpg on the motorway cruising at 70mph. i only got this car 2 weeks ago and thought the poor mpg must down to getting the car serviced so i had that done and it still has not improved anything.

also only today the engine management light has come on! and the computer is saying "INCRESSED EMMISIONS" what could be the problem?

any advice would be helpfull, especially with price of fuel in uk.

PS will putting that REDEX stuff in the fuel to clean the injectors help at all.

Clearly something is wrong if that is what you are actually getting.

I agree with others that you need to check brim to brim, as the computer could be set to the wrong units, inaccurate etc.

My 525d is a very different engine and gearbox and has averaged 40mpg over 24,000 miles. Despite the differences, with the engine in your car, I would be surprised if you didn't get 35mpg for a 70mph motorway cruise.

Again repeating what has been said before, if from a BMW dealer take it back and make a fuss as there must be something wrong.

Could be almost anything; injector issues, brakes binding, towing a caravan - you get the idea.

Sorry can't be more helpful.
