a5 dmf churning noise

  1. A5 General Q&A
    I have a 3.0 TDI 2010 A5 coupe and about a week ago it developed a strange noise that sounded like a bearing going around with no grease in it - a bit like a churning type sound - you can only hear it when inside the car - if you flip the bonnet you cannot hear it. It's not from wheels or brakes...
