A hearthy hello to you all from Finland! Firstly what an excellent community you seem to have here! Pleasure to join.
So let's get straight to business. I went out and test drove a late 2004 MB Sprinter. It has the Sprintshift semi-auto transmission, OM647 engine and it's 2500 weight class. It's the long and tall version, wheelbase being 158". It has clocked a respectable 224k miles.
The car worked fine, but what I did notice was a quite prominent vibration and rumble around 18mph to 25mph. It didn't seem to mind whether I was accerelating or coasting or doing constant speed. The transmission seemed to change very fluently both up and down and performed well under high load as well as very light acceleration. It didn't have problems while coasting to traffic lights and trying to hold to a gear too long.
What could be source for this vibration? Quite frankly the vibration felt like rumble strip noise, but please correct if I'm wrong, but isn't the famous real rumble strip noise -problem only affecting cars with the regular automatic transmission? Wouldn't prop shaft present itself more likely while accelerating?
Thanks already in advance.
