Knocking noise from under engine

[Tomhughes32]

Hi, I’ve recently noticed this loud knocking noise from the underside of my engine. Only really happens on cold start then gets much quieter. Have uploaded a video of the noise. Have read it could be cam belt/tensioner/ water pump issue. Any ideas anyone?

Welcome Tom.

Please do not wait around on here for a response, particularly since your link doesn’t work - well at least for me.

This car is seriously trying to tell you something, and if it were mine I would not be using it until it’s assessed by a trusted local garage. 
Apologies for coming over as being dismissive in this case, but to me, this doesn’t seem to be a candidate for remote diagnosing, but needs to be seen and assessed. 
Kind regards,

Gareth.

That sounds awful Tom, after the first listen I thought it was just a loose exhaust banging against the chassis but after playing it back a few times I'm no longer sure. If it was mine I'd get it looked at sharpish mate just to be on the safe side.

It’s having rear exhaust section modified in a few days so they are going to have a look at it. It’s not throwing any fault codes which gives me hope the engine is still okay. I’m guessing a lazy cam tensioner or a bad DMF. Will have to wait and see

Good luck Tom, hope it's nothing too expensive/serious, let us know how you get on mate.
