Car shakes/judders when i start driving

[Adeelio]

My 2.0tdi for a few months would shake intermittently in idle and also when accelerating normally.

Around a year ago i had my egr valve change, for a different issue, so this rules this out as a solution?

Today i went to a garage who replaced the throttle actuator (as EM sign came up saying it needed replacing- well it came off on and on), this now stops the car from juddering on idle (for now) but still shakes when accelerating. Not too confident on the garage as this fix cost me just over £400. Next step they said was to replace the transmission oil, if that doesnt work then transmission work, to replace the oil it isnjsut under £250.

Few months back when i used to put the ac on it would reduce the juddering, but now doesn't make much of a difference

Anyone had this same issue before? Any fixes that worked for you?

Thanks!
