Turbocharger, compressor, cylinder, control chain – what can be broken now – 1.4 TSI VW

Hello dear community, we have a Tiguan with this be…. 1.4 TSI engine, which we had bought again in June 2009. After three years and a month we had no compression on the third cylinder. After they had already removed the whole engine, they also changed the control chain with immediately. A year later, when we went home from Italy, then the turbocharger was broken and now, only a month later, a control lamp lights up and now the compressor is defective. Cost up to now 3000 euros. What can still be broken about this stupid engine? I spin through… there you buy a VW, so to speak, “the car” and think, except inspection and refueling is nix and now that. A careful and friendly request at VW has been made and you get only a pampy answer, that one should be happy, if even here a kulanz was approved. I know yes, here it swarms only so of the 1.4 TSI damaged, but was broken with someone already ALLES LG?
