ZKD exchange at the friendly in Düsseldorf 2000€ this can be

Hi once called from neugier to the friendly in D-Dorf and wanted to know what the replacement of the cylinder head seals would cost with material on a mv6, because the workshop manager meant around 2T€ so that can be possible I mean is the exchange in mv6 really sooooooo expensive and if no what would he cost about where else?
