Ok, so your car won’t start, you might have a camshaft sensor fault... maybe your timing chain snapped, but how can you check?
You could dismantle everything on top of the timing cover & remove it to see the camshaft sprocket... or you could try this... 🤔
Spoiler: you’ll need a cheap borescope/endoscope camera off eBay for about £15 👍
EDIT: This image doesn’t tell the entire story if trying to confirm a snapped timing chain. To avoid dismantling the top of the engine I ended up taking an image of the camshaft sprocket, cranking the car a small amount, and then re-checking the image to see if the sprocket had rotated at all. In this case it didn’t, which suggests a broken bottom timing chain.
