    I drive a 2016 plate A4 b9 2.0 Tdi 190ps stronic. Car went in for a warranty claim regarding the leaking gearbox. Still currently being fixed. Audi also spotted the fault “pressure too low’ relating to the adblue pump. This I’m told is a single unit including the tank. The part number being replaced for the Adblue tank is A8W0131879AJV. I will try get the actual fault code but was only provided with the above for now.

    I thought this would be of interest to the diesel drivers out there.
