I have seen many issues with EA888 1.8/2.0TSi engine for timing tensioner slipage and oil consumption is the greatest problem which is faced by many owners worldwide.

I own a Skoda Superb 1.8TSi MT (2012 manufactured) with 80k kms in the odo.

My original engine at 54k kms was replaced by Skoda with a new Gen2 1.8TSI on 2017 due to a warped engine head and some coolant leak and there was a lot of vibrations while driving.

I am driving with the new engine and have driven it around 26k kms with and the problem which my car gave was a bad fuel pump and a bad water pump.

Engine has no issues till now.

I have a question for all the experts over here , which i think most of the EA888 Gen2 owners need to know.

My question is that when did VAG update the faulty timing tensioners with the updated one and update the pistons rings with revised rings and con rods for the oil consumption issue? 

I have mostly seens the issues cropping in the EA888 Gen2 engines from the year 2009-2011.  

I'm not sure it's quite what you were hoping for but this site will tell you when (the date) any given part number was superseded, and what the superseding part number is.

Delete all spaces from the number before entering, then hit 'Find it'. Don't be surprised if some parts show a long sequence of revisions.

I don't know of a way to go backwards unfortunately, from a current part number backwards in time through previous versions. I think proper paid-for ETKA can do this.
