Consumer advice on c8 car sale

fencer32

Hoping for a little advice here. Bought a 2nd hand citroen c8 from a car dealer almost 4 months ago. The car had 50000 miles on the clock and as c8 has known timing belt problems I asked the dealer to change the cam belt and associated parts for a new one before I would buy the car. He arranged for a garage to do this and off I drove. Last week a bolt that holds the timing belt system in place fractured and so the engine is a right off (£4000 for a recon one). The garage apparently only changed the belt and nothing else. Citroen uk advise that when changing the belt all the associated timing belt parts are changed with it. The dealer now says it's not his problem because he got a garage to do the work and the garage says it's not their problem because they only did what was asked of them by the dealer.
Either way my usual garage and citroen have both said that there is no way a correctly fitted timing belt system should have failed after 4 months and less than 2000 miles of use!.
Just wondering where I stand legally etc

Did you get something in writing from the sales garage to say that they were replacing the belt and other bits?

No, but the sales garage are maintaining that they told the service garage to replace all the timing belt components as per what citroen recommend
