The hear shields under the back of my 2013 diesel Superb Elegance estate started rattling 2 weeks ago. I had a look underneath and found that one of these fasteners was completely rusted through:

 

 

…and a second was on its way. I’ve replaced the two rusty star washers with new ones today and it is quieter, but I still get the odd rattle. I’m wondering whether there should be some barrier or sound deadening material between the two heat shields where they overlap - which has perhaps fallen out?

 

Does anyone know?

I can't answer that specifically but it may also be worth checking neither of the rear springs has broken.

 

I found some of my star washers missing or corroded after pulling off the drive and hearing a metallic ping bang, replaced them and still had some strange metal knocking which turned out to be a broken spring.

Many thanks.

I changed the rear springs in July for the MoT - so it is perhaps unlikely they have failed already, but I'll check tomorrow anyway.

My sons was rattling on his Seat Ibiza.

Its held on the same and was rotten loose like that.

What I done was cut four squares out of an old thinish door mat ( felt/wire type and quite stiff) and just poked a knife through middle.

put one piece either side of heat shield and refitted the spring washers.

Worked a treat 👍

I had another look at the heat shield today - the rear end rattle had persisted. The aluminium sheet around the middle of the three fasteners had worn away a bit so I made up a large aluminium washer (about 2”) like this:

 

 

 

… which I thought a neat solution, but still the rattle persisted. I jacked up the car and checked the (nearly new) springs, which were fine, then accidentally came across the culprit: the cover for the NSR disc was not attached:

 

 

the metal surrounding the three securing screws had all worn away, allowing the cover to flop around. I’ll start a new thread to work out how I’ll fix it 🙂

When my dust shields went on my old Peugeot they just got removed, more hassle to replace than their actual usefulness in my opinion

The bottom of a beer can also works quite well. I couldn't get a genuine part, but Staropramen is Czech, so I thought that's probably as close to OEM as you'll find. 

I, too, have a Skoda superb 2013, with a loose heat shield. I tried to fix it with the aforementioned beer can bottoms, and retained a little shaking.

 

I'll take a look at a few of these discussions.

It was both a heat shield and the dust cover for the breaks, yet to fix the dust cover! Thanks for the idea!
