M57TU2 running problems

4 posts in this topic

Hi I have a car here which starts fine and idles ok. Anything below 2K revs theres no power and is jerky but over 2.5-3K the power comes back on

 

Theres an EML light on with the following codes

 

003FF0 DDE - Air flow sensor

 

004587 4587 Fuel Filter

 

004501 DDE- Exhaust gas re-circulation, control deviation

 

Glow plug cylinder 1-6 activation

 

Is there any think I check first for?

 

Thanks

 

If I clear it the EML comes on soon after with the same codes

Sticking EGR valve is a high possibility. It'll cause a bad MAF reading which may bring up that fault. I'd remove it and clean it then put it back on. Also check for vacuum at the end of the pipe that controls it. No vacuum will mean the valve will be stuck in a certain position.
