Video is worth a million words... That's was NOT right. You had two "heavy" jerks in there, one at 11 secs. and the other at 22 secs. (although, not as bad). Only guess I have is you still have air in the line that will purge itself out over time... would have thought cycling it a few times should have taken care of it... Have you shown the dealer this?
The jerks may have been me but the speed difference i don't get. I assume when it operates faster that is how it should work.
