my CLK is rattling at idle. From exhaust under drivers door. My initial thought was the cat(s) but having got under there with a long piece of wood I can stop it rattling by simply pressing the exhaust up towards the underside of the car. So I’m thinking heat shield is loose. Does that sound right? Would not expect a duff cat to stop rattling simply by pressing lightly on the exhaust.....what do people think? It’s booked in for annual service in a few weeks so will have it sorted then. Was just curious as to whether it was a £££££ job or a simple bracket fix!
