when revving as you can hear on the video it lags/hesitates until just after 2500 rpm, i've had the car plugged into a snap on code reader and a sykes code reader just to see it there was anything going to appear as a fault but none of them found any error codes and the eml is`nt on

Also when you rev it very slowly it will do it as normal, so it got me thinking that it may be a fuel related problem as when i rev that bit more quicker it just coughs and splurts.

any help is very much appreciated

Thanks i'll get that checked , but surely if that was worn would the crank sensor not kick out a fault because the timing would be out?

no it wouldnt as the crank sensor is still giving a reading as its still working properly.Its just the wrong signal.As jimmymc said its going to be the keyway on the crank pulley.Had it on mine a while back,vaux sell the kits now which consists of the pulley and the timing cog bit as it was apparently a design flaw.Think theyre around 80 quid but worth it.

get a new outer pulley and inner timing crank cog aswell as a new crank pulley bolt.

If the woodruff key has slipped or worn then i would imagine the crank pulley and keyway in the cog are both fucked.

yesterday i went ahead with trying to sort out this problem, finding out that the timing was out about 1 tooth. i bought a new bottom timing cog and woodruff key and fitted them, then got the timing all set up again and put it all back together then started her up to find i still have the same fookin problem! so i am just going to try a new coil pack and better ht leads

unless any1 else has any idea to what this problem may be??
