Help with rattle noise

[Elite]

Hi everyone,

I’m having trouble tracking down a rattle in my Cupra Leon facelift. The rattle comes from the rear right side. It happens mainly when the temperature is high (car parked in the sun / hot weather). It sometimes disappears after driving for a bit.

What I’ve checked so far:

• Removed trim panels and test-drove with them off.
• Inspected wire clips.
• Drove with rear window open and rear seat folded.
• Checked door locks and latches.
• Adjusted trunk rubber stoppers.
• Exhaust shield is fine.

• Dealer also inspected but couldn’t identify the cause.

Here’s a short clip so you can hear it: link on Reddit

Has anyone experienced something similar? Any tips on what else to check would be great.

Have you checked all the door rubbers are clean and free of any wax as well as the paintwork around the door sill and frame? I had this on a Peugeot 2008 and dealer could not find either. I traced it to a dirty door seal. It was a common fault on the original E87 BMW 1 Series, which is where I learnt it from.
