Lack of power

Post by Wilson jacko » Mon May 14, 2018 7:38 pm

Hi all, read loads of threads and still no idea. I have just got a 06 120d m sport with 127000 on the clock, issue is it feels like it’s pulling a trailer. In 6th on motorway at around 70 you put your foot down and nothing happens, start going up hill it slows to the point I nearly need to change down. Just serviced. It does rev freely with no smoke. Don’t know if it is turbo (no noise) abs pump or dtc issue. Any clue

I have seen similar symptoms with VW tdi engine when the MAF is faulty. Is it possible to unplug the MAF and see how it runs with the default settings?

It's worth a quick check, just pull the charge pipe off and take a photo with your phone.

I was going to say a boost leak (split/cracked charge pipe), but as you've no weird noises that's unlikely. Still worth a quick check though.
