Guys, can any 2010+ B8 RS5 and RS4 owners who have had catalytic converter and/or emissions system issues please contact me ASAP via [email protected].

After reading about a number of cases where the catalyst components have broken up and come out of the exhaust system, I too have now had to replace a catalytic converter in my 2011 RS5.

Tell-tale signs: Emissions test failure, strange rattles from the exhaust, visible debris in the rear silencers.

I engaged in a dispute with Audi UK, and after preliminary discussion with an emissions control specialist it seems that they may not be fit for purpose.
