I have a few tips for improving mpg, but do you have any?
Fit a flat panel filter. Yes they give you more bhp, but on a TDI engine, they will also improve spool up and low end pick up. Therefore you can drive your diesel off boost more and get better mpg.
Switch Aircon off. Aircon-pressor loads the engine. This give 3 to 5 mpg more switched off!
Remove Roof bars. The Cross rails hold you back, disturb the air and cause you to use fuel.
Switch Cruise off. Yep, another winner but an ankle acher.
My V6TDI at 70, everything on as above. 33mpg. switch off as above 39 mpg. At 60mph, 42 mpg. Big difference isn't it?
