BMW Diesel Service to increase MPG - Advice Please
Discussion
Not really much to go on here. As it currently sounds like... well a service, and one that is sold with 'up to' 20% increase in economy. I think I'd be finding out precisely what was going to happen is a good idea.
edit: 'Quality Enhancement' sounds very much like marketing speak for technical bulletin/fixing a fk up.

I dont think they seem that corrupt, they do a rolling road test before and after to show the difference. Im not mechanically minded enough to know fully, Could ti be something as simple as slightly larger hoses, give it a good clean out, etc???

Stick some random "treatment" into the oil or fuel and re-calibrate the OBC to show better MPG than it's actually getting would be my guess.

Dyno runs before and after make it interesting..
I initially thought this sounded just like the advertising on additives or "magic" services which promise huge performance and efficiency gains, with the small print being "only where the car was completely fked to start with".
