I'm hoping someone is able to help me.
I have a 2007 Audi A4 Avant with a BRD engine (2.0tdi 170bhp).

I have the same engine, mine was A2C53099815 when I had to replace it. It is common for them to have build up around them, I would give it a good clean first before replacing it. Whilst you're there take apart the manifold and EGR and clean that as well. This made a considerable difference to...
