2004 C270CDI
270 rough idle

I had an experience I would like to share with the forum.
My 2004 C270CDI developed a really bad vibration coming from the engine. I thought it might be the aftermarket engine mountings I had replaced last year, but I did not have the time to investigate.
Today I replaced the battery, and lo and behold, the vibrations are gone!
It turned out to be a weak battery...
I was wondering if someone perhaps have had the same experience?
