Modern boilers do not have pilot lights any more. They are all electronic ignition.
If you go to Baxi.co.uk and go to the installers section you can download the installation and maintenance instructions which has a fault finding guide near the back.
Your installer should have left a copy with you when it was installed.
If your'e not confident with this sort of thing then don't attempt it - call an engineer.
The boiler you have is relatively new and providing you've had it serviced, should be ok.
