MY13.5 (CTHE) Just topped up with 2L after the warning light came on at 5400km (2 months old).

Yes, I am ashamed that I didn't check the level sooner but I mistakenly assumed they addressed the consumption issue with the engine update.

For those keeping score: my running in tactic was to drive it like I always will, no babying it (mind you I drive for engine longevity at the best of times)... but I did give it some stink in its first 100kms.
