Your engine needs a cleaning. Your likely suspect is carbon build up in the engine, turbo or egr valve. try running some cleaner threw your oil before a oil change should clean a bit of the crap out. You should replace the spark plugs also since they are most likely due for a change regardless. (use bosch 4 point plugs they are the best) have the turbo checked by a garage to make sure its not clogged or falling apart as well. and check all the crank case hoses. They tend to get full of sludge after some time.

wouldn't hurt to clean out the throttler body as well
