That is not the engine code. That is merely a serial number. The Gen2 code for 1.8TSI is CDAA. You should try to identify the engine code it is usuall 3-4 characters long. However, I would be amazed if they were able to fit a later model 1.8TSI engine to the older Suberb. The Gen3 engine has a higher power output 180hp vs the 160hp for the Gen2. That being said it might be difficult to determine the engine internals, unless there is a receipt or statement from Skoda Workshop that built the engine.

The design was changed from 2013 onwards. The correction procedure for the Gen2 engine for the oil consumption is actually to switch to the Gen1 pistons & piston rings. If the parts for the new engine was obtained from official dealer and the parts were sourced after 2013 you should be safe. However, if it is an engine produced 2012 and before (or a used engine, that has not ben overhauled) you may have the issue. If it does not consume excessive oil you should be good to go with respect to the oil consumption. Timing chain issues has different symptoms, like misfire, in worst case damage to valves if they get out of timing with respect to the crankshaft/pistons.

My vote is on replacing the oil rings on the pistons. I had excessive oil consumption on my 1.8TSI. The infamous CDAA / 888 Gen2. I got it sorted out by Skoda. They replaced new pistons, new pistonrings, connecting rods, timing chain. 100% of the parts and 70% of labour was covered by Skoda. You should not buy a car with the Gen2 engine (years 2009 - 2012), unless the piston rings has been exchanged for another design. There is a lot of information on the topic available. The limit for the maintenance recall was 2000km/ 1 l of oil.
