It's a VAG part, so will be found in lots of vehicles of the period, in the throttle body. Not that common a fault, but the solution is to replace the whole body due to a fault with a 50p part that can't be sourced. It's not a fault in my Octavia, a Touran actually.. Your comment about being " confused by completely different cars" makes it sounds like you naively believe every car has its own unique parts?

Found this hunting for a new spring as had the same issue. Nothing to do with mods etc. Just bad part design by VW...

Interesting question, it's not wasted energy having "more" noise from exhaust... as the exhaust system baffles the sound (absorb to dissipate at heat energy) so it's there anyway. If you like the sound, technically less energy is wasted as sound because it's useful to you, rather than wasted as heat in the surroundings.... Edit: whereas the "sound device" wastes energy as it requires extra electrical energy to produce the sound, on top of that wasted by baffling the exhaust.

Saw this, made me happy how good it looks. Didn't care about the words. Had to share. Wife wouldn't care. Came to forums, found similar post. 😂 https://www.bbc.com/news/uk-england-cumbria-55724754
