What can I do to improve my 520d?

I drive a 2008 BMW 520d msport but am really disappointed with the sluggish lack of power, i have had the dpf and rest of it decarbonised (which still only returns 40mpg) is there anything i can do to make it feel more like a BMW should? eg. remapping etc and i would appreciate any help to point me in the direction of a decent company that could remap the N47 engine (that has had no timing chain problem) and doesn't charge a fortune. Many Thanks Tony

Hi Tony,

There are many tuners and chips specialists, such as Celtic Tuning, Quantum Tuning, or RaceChip and for the most part, you can order the tweaks online, and they’ll simply send you a USB stick to plug into the car’s diagnostic system. That said, it sounds from what you’re suggesting that the car has some specific problem. While a 520d isn’t the quickest car around (and I’d be interested to know what you’re comparing it to when you say it feels sluggish) it shouldn’t feel excessively slow, and you should be able to squeeze more than 40mpg out of it, depending on your driving style. When was it last properly serviced? Have you had it inspected by a BMW dealer? Have you tried driving a similar 520d to see if it feels the same?
