So there are 2 problems, appears i have both. I will explain both below but are all related to the back box!. My damn phone ran out of charge so couldnt get photos this time round.
1) The exhaust Valves are loose - If you put your finger underneath the Pipe coming off the backbox, just under the valves there is a little circle that sticks out. This is the pivot where the Valves sit on. My right hand side one moves alot and the rattle exhibitts out the tailpipe, more so under throttle. Holding your finger over it with pressure and revving it goes away. There is some foreign guy on youtube shows this, but wondered if it was legit and it is.
Example for this one is noise is (this isnt my car just an example)
2) The Exhaust Internal Plates are loose - This is the sound most annoying and exhibitted more with a decat as more pressure and noise passing through them. Inside are a few different plates including some gauze, bit like a maze which is used to reduce drone on a motorway. These are making the ticking noise me and a few others are experiencing all the time but more so on the cold start whereby the cold start high revs take place. Guessing some are worse than others.
Unfortunately we didnt have time to fix any of this because it needs a decision from myself as to which route i take.
1) Seek Audi under warranty, but this could happen again AND they could be twats about the fact i have a decat despite it being a bigger issue than just me. Quickest appt i can get with Audi locally is 24th April and im away anyway.
2) Weld the Valves or take them out and try stiffening them up using a tighter spring. then remove or re-weld some of the internal plates so they dont rattle / cause the ticking.
3) Get an aftermarket exhaust. and send my Audi one back to them covered in dog ****
I would rather the Audi solution as it costs me nothing and gets them to realise they have a defective product, going to have a ponder but at least we know its the backbox.
