Hi,
I’m new to the forums and looking for some advice. I have an A5 3.0 tdi Quattro ( same engine as the c5 I believe ) which I have up for sale. Had someone come to view it and we went a test drive, he said the engine has a whining noise coming from it but to me it sounds normal. It sounds exactly like this video I found on YouTube. Is anyone able to confirm if this sounds normal.
many thanks
robert
