As I’ve seen in the comments a lot of people have a lot of problems with their heat shields. I’ve had mine tightened back up again numerous times and eventually it’s got to the point where it’s unfixable. A guy at the garage has ripped it out and said that I can use my car as normal without it. My car is a 2012 plate and well looked after. I’m just panicking in case I do need it as when I’ve looked online it says it could possibly cause fires etc and protects your exhaust. Does anyone else not have theirs on?
