Recommended plugs are NGK BKR7EIX Iridium plugs around £28 from ebay. I received mine in two days. Take one out of the car and have a look at it maybe even post a picture up in possibl?.

The car also slightly hunts abit when idling

Mine doesn't hunt at all, but that starting issue is there every day without fail

Could well be the infamous cylinder coked up with gunk as it's a very common problem with the tfsi engine. apparently the new polo's have 8 injectors to overcome this so worth a think about the tfsi with coking in the inlet side?. There are many threads on this and I replied to a good few of them myself when I first started using the forum to its full and never came off it :signLOL:

I'm wondering if this could be failing injectors, or clogged injector nozzles, pity there is no easy way of checking and or replacing them without the removal of the inlet manifold
