Not yet. Car not on the drive at the moment! Will do when I get a chance - and before I order!

Oh thank you - I didn't know that. Most of the UK options seem to be TOPRAN (HANS PRIES) branded which has quite mixed reviews online.

Thanks. This appears to be the right part, and I've heard of Bosch - so seems like a goer... https://www.buycarparts.co.uk/bosch/1154807

And further less dumb question. Would me replacing a relay have any impact on our Skoda Used warranty?

Thanks both. A local parts dealer had led me to believer they couldn't get these parts in. But a bit of googling seems to show they are available. Really appreciate your help. Final dumb question. Is it simply a question of removing the old one and putting in the new one? Do I need to disconnect battery or anything to do it?

Sorry to resurrect an old thread, but I had the same issue on my Octavia Estate 2018. The Skoda Assist man came out and seems to have fixed it temporarily, but said that the Main Relay needed replacing. Which appears to be the same '645' referenced above. My question - can I get one of these from anyone other than the main dealer, or am I going to have to take it in to replace it? PS sorry if this is a really stupid question - I'm totally ignorant about cars and new to Skodas!
