Timing belt was replaced about 30,000 km ago, so I wouldn't expect that, but I guess it's worth checking. I visually inspected the sensor cable, but I'll check the wires properly. How do you determine if the sensor is actually defective?

Yeah, those electrical gremlins are the worst! If it's not something obvious like a damaged cable, it's tricky to know for sure without proper diagnostics. I'd hate for you to replace the sensor and it turns out to be something else entirely. Might be worth biting the bullet and taking it to a workshop to get it properly diagnosed. Frustrating, I know!

You're right, chasing ghosts is getting me nowhere. Took it to the shop; turns out it was the crankshaft sensor. 340€ later and she's running like new again. Thanks for the nudge!

Whoa, sounds rough! I'm no expert, but that sounds like a timing issue. Is your timing belt in good shape? Maybe it jumped a tooth? Or is the sensor cable well connected? I had similar misfire symptoms when a squirrel chewed through some wires.
