Does anyone know if the PCW exhaust mod also addresses the infamous cold startup rattle? Or is that something that's easily fixable when he's doing his thing to the back box? I read somewhere it's to do with a valve pin that Audi couldn't be bothered to work out the right tension for, to stop it rattling on cold startup (as the default startup is in comfort mode with valves closed) and most RS3 FL's have that tin can rattle, is that right? thanks guys
(I have a 2018 FL saloon with sports exhaust)
Start up rattle is advanced catalyst warm up phase.
I have a FL and have it mapped out
