I would expect bmw to know of all.the services they have done whether under warranty or not. And we see the.other post saying an owner can get.that information. Bmw just doesnt want a prospective buyer having access to.that information. Ever notice.how used car.sales.never.has the x owners.service.records? It is a risk to the sale letting the buyer know the full.history. I bet the unfortunate owner here will see.in the cars history.indicators of the issues he had with the engine.
