Hi all, an update on my car - the engine noise is horrific 24/7 now. No mechanic can tell me what is wrong with my car. I've had 2 test drives with Audi technicians. One of them admitted that the emissions update is known by Audi to change the sound an engine makes (despite Audi UK repeatedly telling people it has no impact on this...).
More interesting for those who have had the EGR valve problem - the service manager of Swansea Audi, David Jones, admitted that Audi UK know that the update does break some EGR valves - this is due to an underlying issue with the valves which is then triggered by the update. So anyone fighting Audi on this front please feel free to use this admission against them as you shouldn't have to pay a single penny to put this right.
