Lumpy acceleration is often the case with diesel engines. If you own a newer Mercedes, you could check with different Mercedes tuning companies. What you need is a chip or powerbox, which will electronically adjust your engine in such a way that your engines power and torque goes up (through optimized engine computer), and your miles a gallon might also go up. I estimate that a power increase of about 10 to 30 horsepowers is possible. You can check out different Mercedes tuners, for example Brabus or Lorinser. If you own an older model, you can still search for a chip on the internet. If you can't find anything, an individual chip tuning might be possible through analysing your engine by a tuner. However, I'm not sure if the second suggestion is a realistic one.
