IMS Failure Issue

Hi ,

Currently im suffering in a IMS failure related to replace the engine block , porsche dealer in NY charged me $26000 for the repair but only the block is new all other compotnent will be transfer from the old engine , is it something that i should have all parts in new since is a complete engine replacement repair ?

The other question i have is ,  i brought the car used through a Land Rover dealership and only eligible for 25% reinbusement(IMS settlement Class act law suite ) from Porsche of North America , because is not brought at ACPO . is it right ?

Thanks for the answer and advise
