Hello -
I have a problem with a VW Sharan cylinder head replacement (carried out by an authorized workshop


)
The turbocharger, however, failed immediately (within a few kilometers of taking possession of the vehicle).
Are there publications where an oil change is performed during repairs on an open engine?
prescribed or at least considered necessary? (Because it hasn't been done - and we suspect an immediate connection - violation of a hygiene rule)
Or do we really have to believe that it's normal that not only the engine, but also the turbocharger, 'bids farewell' at around 8o.oooo km?
Who knows what?
Greetings from Miodomo
