Dpf blocked up (if you have one. Automatics, estates, all signums. You will have a 0.5 on your drivers door sticker where your chassis number is if you have a dpf.)
Symptoms. Are lack of power through out the rev range, poor mpg and in extreme cases engine won't start and eml on.
Remedy, try cleanin your dpf if no succeeds then either replace dpf (expensive) or remove the insides then refit and get the software removed from the ecu by means of a remap.

Swirl linkage not on. Symptoms poor performance sometimes and also some go unnoticed. Remedy check bar and try the diy fix or in the end buy a new manifold expensive but will cure faults and increase power and mpg. To prevent future failures you can semi blank egr and vent oil system to atmosphere

Throttle body intermittent problem or stopped working
Symptoms, Juddering and also engine management light on not always with codes relating to throttle position. Remedy is resolder the circuit board or remove your throttle plate to see if that eliminates the problem
