Yeah I was looking into the same as it being a fault that’s they should be fixing but didn’t get much luck. Seems issues with Peugeot, Citroen and ford as well. The issue is it’s a part that does wear down but as it’s in the engine it causes other problems and also requires so much labour to service. I decided not to continue trying to get them to pay for it as no guarantees and needed it fixed quick and putting it to them would have probs cost me a lost more than my garage.
