I have a -09 CRD aut Limited and I can feel a rumble on 4th and 5th gear when driving so that the revs are somewhat between 1500-2000rpm.
Now, I haven't been able to locate the whereabouts of the sound, but I'm reckoning it's coming from the transmission, since I haven't been able to duplicate the rumble with lower gears.
The car has 240'000 km's on the clock and it has been properly maintained so far.
Any1 had the same kind of problems? What was the cause?
I live in Finland and there's only 5 KK's here as far as I know, so can't ask around from local workshops.
