Engine hesitation after service and cam belt change.

Bosh spark plug for this engine ?

According to ETKA, the only part number for the 1.2 TSI 16V EA211 is 04E905601B, and they are NGK.

I agree, the NGK equivalent for this VW Group part number 04E 905 601B, is NGK Stock 93231 = PZKER7B8EGS only difference is that they come in NGK branded boxes.

All VW Group cars that I've run and worked on have come from the factory fitted with NGK spark plugs re-branded as VW AG, and I've always replaced spark plugs in them by using NGK spark plugs.

Typically Bosch spark plugs are "economy" service replacement alternatives.

Bosch spark plugs also work well (tested on several occasions), although installing the manufacturer's recommended plugs is probably the most reliable option in the long run.
In a globalized world, it's possible to buy parts that, even if they are exactly the same, don't have the same quality controls everywhere.
I also had ignition problems with an NGK spark plug, I bought the same ones from another place (all of them), replaced them, and everything was perfect... easily solvable and not very worrying.
