What are Fault codes P0441 + P0704 On my 05 Plate Octavia VRS?

Look in the workshop manual for exact specification.

Have you checked the firing to ignite the fuel? Aside from timing, the proper heating of a glow plug is important to ignition.

code p0129 refers to barometric pressure-two low===causes wiring---BARO sensor, ---mechanical fault
code p0441 refers to evaporative emission (EVAP) system--incorrect flow detected=== causes ---hose connection/s---intake leak--EVAP canister purge valve

replace the BARO sensor and the purge valve after seeing that the filler cap is on correctly.

code P0441 EVAP purge flow monitor fault.
