firstly, apologies for the different vehicle! it comes second to my golf But i have a 108 cdi for business/bikes etc and it seems to have this rather odd flat spot in it when its warm between 2200 and 2800 rpm. seems to get a bit shaky and smokes. If you blat it through this rev range, it doesnt seem to smoke or rattle, its only when maintaining speed or a certain throttle position. Again, it only happens when its warm. when its cold, it revs very nicely! there doesnt seem to be a change in performance or mpg, just ****es me off!! If anyone might have any ideas on where to start with such an issue i would be very grateful! Ben
