Smart 450 Timing Chain Replacement - didn’t go to plan 🤔

I bought a Smart Fortwo that needed a new timing chain. Simple right.
Maybe not

I hope you turned the gas off after you finished welding :)

Hope that was a genuine Mercedes timing chain, I’ve replaced a fair few of the non genuine ones that customers had had fitted a few hundred miles before and the rattled like hell.

Was the code saying cam sensor error?
