Hi fellow Landys. I have a strange grumbling noise coming from the front drivers side of my fl2 2011 2.2td4. It sounds like something is loose or like the exhaust is blowing but coming from the side of the engine where the pulleys and belt is situated. Sounds worse at low revs and seems to get louder when idling after driving for a 20 mile trip.

We had the same problem with a noise from the front of our 09 MY and that turned out to be the alternator pulley bearing worn replaced the alternator and been perfect since.
Hope this helps

Had my mechanic look at it today. He thinks it's the tensioner on the belt or the belt, just getting prices now for parts. Thanks guys for the response 👊😉

If he thinks it's the tensioner, then he could be mistaken. A faulty overrun pulley on the alternator will often make the belt tensioner oscillate, which looks like the tensioner at faulty, but more often than not it's the alternator pulley. 2009 Rimini Red SE TD4. Soon to be sold.
