After much reading and noticing that my mileage (both OB computer and observing km per tank of gas) are screwed up, see below, I definately think something is wrong.

1. Doing 120 - 130 km/hr OBC is showing mileage as 6.5-6.8 L/100 Km (definately used to see 8-9 L/100 Km during morning and evening commute)
2. At the same time I got 200 ~ 250 Km out of half tank of gas (used to get about 300-350 per half tank)

Guess I will have to wait till my appointment. Having said that from my research two common culprits are purge valve and DMTL pump with these codes (althought codes are not identical) and both look fairly easy for a DIY'er.
