Another possibility if you don't expect to use a Rivnut tool in the future is a manual version - just a nut and bolt and some grunt power (a long handled wrench is helpful). Here's an M6 one on aliexpress for example: https://www.aliexpress.com/ssr/300000512/BundleDeals2?productIds=1005012182413869%3A12000057813458459&pha_manifest=ssr&_immersiveMode=true&disableNav=YES&sourceName=SEARCHProduct&utparam-url=scene%3Asearch%7Cquery_from%3A%7Cx_object_id%3A1005012182413869%7C_p_origin_prod%3A&pvid=c1abb190-ef27-476f-a373-90befdcb3ef6

How about a Stormy Petrel?

There's a brace of those guys in the wood behind me, and every morning they hold a competitive hammering event round about dawn. I suppose it helps the crows wake up ...

There's nothing coming up on the usual go-to for parts - lllparts.co.uk - but both part codes show up on skoda-parts.com, along with lists of the applicable vehicles. Hopefully these will help clear the fog a little. https://www.skoda-parts.com/spare-part/1k0937087h-control-unit-skoda-28666.html https://www.skoda-parts.com/spare-part/1k0937087pz00-central-control-unit-skoda-27602.html

That would likely be a decider for me.

I'd like to learn more, please.

They're known as 'burls' and are usually the reaction of the tree to some insult or intrusion into the bark layer. The complex growth patterning - "figuring" - within burls makes them highly attractive to woodworkers.

Here's another source JIC; new RHD door mirror, heated, complete in primer 27 squid from ali. Only thing missing (for me) was the entry/exit puddle light led. Once the weather improves I shall see if I can transplant the old led fitting into the new housing. https://www.aliexpress.com/item/1005008630176919.html

One other quick check; swap the front wheels over and see if the driving behaviour follows the wheel or stays as-was.

That suggests your tracking is out, perhaps adjustment, perhaps wear on the various suspension elements. Were it mine, I would get the tracking checked.
