Hi Guys, just got a new car which is an Audi 2015 2.0litre tdi. The car is great to drive but when The car is low revving as in pulling away from lights or slowing down to go over speed bumps there’s an weird rumbling/ticking sound. The sound only happens when the revs are in between 1 and 0. I will try attach a video but it’s hard to hear on the vid, any help is appreciated

cheers
