I have recently had an issue where there seems to be excessive vibration coming from somewhere in the engine bay. It went away once speed increased, but was also intermittent. Took my car to the garage and they diagnosed the over-run pulley on the alternator, apparently these are fitted to reduce the vibration and backlash, but they seize up and will free themselves for short periods, however eventually they will seize for good before breaking the alternator. Cost £125 including labour (not a main dealer)
Forgot to say it's a 2013 SD4 auto @ 70knives.
I hope his helps if you have had similar problems

that's worth making a note of, as our motors get older.

As a complete newbie to that area of things, is there any way to manually check the current condition to pre-empt the issue? Learned to drive in 2011.
