Replaced the cam chain tensioner. Noise is still there, exactly the same as the first vid!
I've now checked the big ends, little ends, crank end float, changed the belt tensioner, repaired some broken cables, checked spark, replaced cam sensors, checked compression, checked the injectors, removed the head and checked the cylinder liners, checked the valves, checked the cams and cam towers, checked the cam timing gear, removed the belt to check ancillary pulley faults, replaced exhaust intake and cylinder head gaskets, gone through ECO reset and setup, map whacked it, and set the valve gaps.
I'v also tried removing each coil pack in turn to see if it affects the noise, but no difference to the tapping.
Driving the car the tap tap is not there unless the engine is under load in a high gear, when it actually sounds like more of 'clack clack' than a 'tap tap.'
Apart from the confounded noise the car runs perfectly after all of this work, very smooth and loads more power than beforehand!
I will get a few more vids to upload though.

WAG, maybe clutch related, maybe a warped clutch disk. I'm guessing the car shifts perfectly.

Car is shifting fine. No change is sound with clutch depressed so I'm guessing it rules that out. My only guess now is that it is a gudgeon pin. I'm so fed up with it now 'm thinking i'm just going to spend the money and drop a recon engine in...
