yup did trans mount at same time and both donuts were replacved in past 6 months also 90% of bushes done in past year - control arms front and rear, sub frame, dfiff, anti roll bars, drop links etc.... a lot of work. Car was shaking like a junkie in cold turkey on the motroway. Just need to get he idle vibration done and its sweet. Engine is good, MAF, air filter, EGR+ intake cleaned, all intake cleaned and sealed with new O--rings and spring clips. Gearbox flushed twice in past year fluid is now nice and clean. Injectors are sound and tests in Star + fuel return tests were good. Flap Motor good. I really don't think its the engine its self its runs good and is much quieter and smoother than my old mans with similar millage.
Don't get me wrong the vibration is much better than with the mounts that were on there but should be better than it is. My old man has a W210 same year and his you cant feel any vibration and its on the original mounts with 200k on it.
