Exhaust heat shield rattle

[Wilkinson]

Hi Guys,

Anyone had a rattle from the exhaust heat shields when the car is stationary after it has been on a longish run and is thoroughly warmed through? The sound is more than the normal expected tinging of the exhaust as it cools and it sounds like either a loose heatshield or a shield vibrating against another component. It's only obvious when the car is ticking over and really hot - but it is loud.

Car due to be checked shortly at Dealers but just wondered if anyone had experienced this problem and what precisely it was found to be. Car is a 2.0 SE TFSI

Not heat shields. Sound is coming from exhaust itself. It's a strange vibration / resonance which does not appear to be associated to any variation in engine speed. Engine idle is steady. Workshop Foreman came for a run and inspected on the hoist afterwards. No amount of adjustment could remedy it. He had never come across anything like it and needed some time to try and work it out. Watch this space.
