Our 2015 Twingo with the 0.9TCE has recently become hard to start, turning over but not catching every time.

A quick scan with a code reader shows P0340 and P0341 related to the camshaft position sensor so either cleaning or more likely swapping it should do the trick, but I’ve not found any clear instructions on where exactly it’s located. The Twingo is rear engined, with access through a hatch in the boot, so I suspect it may be one for a garage with a lift (and a clue).

Don’t suppose anyone can shed any light on where to find it?

Nope, sounds normal other than the failure to start. Try again and it works fine second time and drives normally with no obvious noises or lack of power.

Just looking online it looks like its on the top of the cam cover so you should see it from the top.

They can be a bit difficult to work on because of the engine position but they are doable, the chains on these are weak though and normally when they start to stretch they struggle to start and you end up with a fault code for cam/crank or cam correlation. Have you checked live data to see what its reading and if it matches the normal signal ?

Perfect. I’ll take a proper look for it tomorrow.

It’s only a cheapo £15 code reader, so very limited in what it can read.
It’s 8 years old but has done less than 20k miles so I’d be surprised if it was mechanical wear to the chain, and a £30 sensor is an easy thing to start with.

Oil level is right at the top of where it should be.
