Unfortunately on the website the part I selected and ordered for click and collect did not fit a Citroen C2, nor did it fit a C1 but it DID fit a C5 1600 diesel. The part supplied Number 156PC0010. The number on the TOPRAN box says 723768755. I have Emailed Head office to explain this and also Europarts as they are saying this part fits ALL too! I did not go ALL the way BACK to Sheffield as it would cost more in petrol than the cost of the PART. But instead I used it on our C5, which is a perfect FIT. I have worked on cars for years fixing things as a DIYer. My son has his OWN garage so we KNOW a lot about cars between us, him being AUDI trained. As my TEACHER used to say MUST TRY HARDER GSF.
