I'm not sure if the throttle adaptions have to be relearned, see how it goes after a few runs

I can't actually reset adaption on mine either. iid will only do 2006+

Ideally adaption should be reset after changing any sensors, but the Motronic is a quick learner and should sort it's self out after a few runs No7 - 2003 V8 Vogue

Well my new maf gave pretty much the same readings as my old one but I left it on, 200 miles later the lights stayed off so I think problem solved.. thanks for all ideas  2003 4.4 Adriatic Blue FF
