I have a Polo 1.9 TD with AAZ engine. My problem is that when it is running around 1500rpm in any gear, the shaking of the engine raises noticeably, I would say it is too much, and the vibration of the car becomes quite disturbing. Especially compared to other rpm levels below or above. What can be the cause of this and how could it be improved? Can it be the problem of the engine mount that became worn, or maybe accumulation of dirt inside the engine?

By the way, when the engine is running idle at factory power level 900rpm, there is too much shake again, but by raising the idle level to 1000rpm and above the shaking drops back to normal. Have no idea if the two symptom relates to each other ot not, just mentionning.
