Hi All. 2017 diesel 150 4x4. I have a loose heat shield. It is secured by large, circular, spring steel washer-type affairs encased in a plastic housing. Would anyone have a part number for those, please? I can find plenty of the spring steel washers, but can't find the plastic surrounds?

If anyone's in the same situation, I can pass on some news. The parts are a 2-part plastic cage which sandwiches the aluminium heat shield, and then a spring steel washer that fits up against one half of the plastic cage and screws on to the stud welded to the bodyshell.

You can buy the spring steel washer (which is the bit that rusts and falls apart - the plastic cage is fine), if you order VW part Number: N90796501. Loads on eBay.

Just press the new spring steel washer into the plastic cage and screw it back on to the stud.
