I've recently purchased a 525d m sport 2007 (pre Lci) and have started to notice a severe lack of power when accelerating. Have owned the car for a little over 3 weeks and didn't seem as bad when I first got it. It's an auto and the kick down works as expected but for example, overtaking on a motorway around 70mph, I put my foot down and although the auto box was downshifting to accelerate,the car was barely moving and was a slightly embarrassing moment when the car behind me had to change lane to pass me,as normally I would have had ample time to execute the manoeuvre.
I'm going to take it back to dealer I got it from to look at but would like to go there armed with a bit of info just in case I get fobbed off? I'm still getting used to the car but I'm sure this can't be right? many thanks for any info.
