Skoda Octavia Hybrid Turn Signal Problem

Sounds like a bad connection. I had a similar issue with my old Renault Megane. Check the bulb socket and wiring for corrosion or damage. Could be a broken lens too.

Cheers for the quick reply! When you say 'bad connection', where exactly should I be looking? I'm not really clued up on electrics.

Check the connector block where the wiring harness plugs into the turn signal lamp unit itself. That's where I found the issue on the Megane. If you're not comfortable poking around with electrics, might be best to get a workshop to take a look.

Took it to the shop. It was a dodgy connector on the turn signal lamp, just like you said. They charged me 95€ to sort it. Annoying electrical fault, but at least it's fixed!
