Both my GLA and Audi TTS make sounds after shutdown. Sometimes it’s the fans, and/or turbo depressurizing, and/or catalytic converter dissimilar metal cooling. As Wayne cites there’s all sorts of stuff auto-happening especially on modern turbocharged vehicles. And yes it’s very ambient hot here too right now,
So, in my examples a whir, a whine and a bang.
Hey guys, hope everyone’s doing well. So I’m stuck, debating on either installing an air intake or an air filter. I’m looking for reliability and gain, which do you guys think it’s best for anyone who’s done any of these mods in their v? Thanks!
