Is there any way of telling what type of gearbox I have in my MK2 Octavia vRS? Code shows JLW below but is that a different code to being 02m etc? Or is it a JLW gearbox?

02Q and 02M are gearbox families, JLW is a gearbox code (which pins down the exact ratios inside, etc.).

Google says it's part of the 02Q family, see on here for example: https://workshop-manuals.com/audi/a3_mk2/power_transmission/6-speed_manual_gearbox_02q_front-wheel_drive/technical_data/gearbox_identification/code_letters_allocation_transmission_ratios_capacities/

Awesome, thank you

You're welcome.

Would a gearbox from a 2007 Seat Leon Cupra be a direct replacement for my petrol Octavia vrs?
