Audi A5 3.0 TDI Stage 2: Smoke / Sound on the dyno 

It's removed, the car has a straigth downpipe as you can see in my other videos.

You think it needs a wash? Hmmm.... you're right, of course! A few weeks ago i gave it away to receive a full polish and paint conservation.

It was, until the software was re-programmed again. Since then, there is almost no smoke at all.

Although it's a diesel engine? I think it's a bit different, but nevertheless it's good!
