My 1.5 SE L petrol doesn't use adblue so does it do some sort of regen and if it does how do I know when it kicks in, is there a warning light.

Yes the petrol with a GPF does do some sort of regen. Differently from a DPF, when hot and when off the accelerator. 

 Try a search.  Briskoda gpf Regen.   Mk3 Octavia threads about warning light flashing etc.

No warning light for the car doing automatic things. 

 But when you might need to do a forced regen there is.

Ad blu doesn't have anything to do with regeneration even in diesels that use it.

Thought Breezy Pete but wasn't sure. 

Cheers
