Hello Forum. Very excited to say I have now done close to 150k in DMS remapped 2006 535d. Now I'm not scared of the loud pedal, but not a murmur from engine or transmission, and up to 120k, when I woke up to decent independant servicing, not a squeak from BMW dealers when serviced. So I've gone mad and bought another 535d, 2008 to replace. Do I need to use DMS to get the remapping done? I can't, by the way, imagine a better car, and what a good forum!
