Skoda Yeti recommendation for purchase?

Hello – maybe one of you can help me. My father would like to buy a Skoda Yeti (2.0 tdi with 4×4 and 110 hp) The workshop of his trust (free) advised against it (of all current VW group cars). Especially the 140hp diesel should be unreliable and also the 110hp variant should have its problems. Can anyone confirm this the current cars from the VW group should not be particularly reliable? Does someone have a Yeti and can do this better? The one from the workshop said that the oil pump often causes problems. Would I be happy about many helpful answers and would like to thank you in advance:-) MFG Michael
