My first post, so bear with me please.
I bought a 2006 530d M Sport Auto a couple of weeks ago. It's a fantastic car but I've been pretty shocked by the fuel consumption, particularly when driven with a featherlight touch! I understand that it's a heavy, powerfull car but based on published MPG figures I expected better than 37/38 MPG on a 100 mile 70MPH cruise! I had a brief search online and see that most people who've commented have similar tales to tell.
I stumbled across the following outfit:
I spoke to a local dealer/fitter and he sounded convincing about the upgrade and the improved fuel consumption they claim (up to 20% improvement) but I wondered if anyone on the forum had any experience of them? If not, can anyone vouch for someone I could use up here in Edinburgh?
