Hi all, new here! 

Had my fabia VRS about 4 months and it’s great fun until recently...

from cold the car starts okay but immediately “misfires” which lasts until it has a bit of temperature in it.

whilst it’s “missing” there is quite a loud clatter from the head. I know these can have the problem with the cam lobes wearing and putting a hole in the lifters but wouldn’t this be apparent all the time not just when it’s cold? 

Thanks in advance 

@Boase93 - When was the oil last changed? This sounds like it's probably needing done.

Full service last weekend made no difference

Take the rocker cover off and have a look at the cam and tappets. Take photos the best you can and post them here and will try and see if there's cam wear. 

 

 

There is slight wear on the cam lobes couldn’t see the buckets very well but assuming that that’s what it is definitely sounds like it’s for the head and can hear it through the exhaust
