Engine problem 9-5, 2.3T (B235)

Although there is the opinion of SAAB Deutschland (Customer Info Center) published by 1.SSAB (LB-S***) in which it explicitly states: “…that it is a customer support program with a retroactive garntie….”, but what can one do if a (worst) manufacturer of the world’s largest automobile conhzer (GM) leaves the concretely affected in the rain?? For now 10 days I am without a vehicle (commercially urgently required) and still stands an offiz In this case, the damage images are precisely defined: the complete block as well as the cylinder head and the turbocharger are affected… (somewhere in the forum I read that it is only 4 out of 100 (with 400,000 affected SAAB (according to the report of the car, engine and sport of 28.01.) but that is nevertheless 16.000….) There should be some who assert their right together. Or should I be the only affected person?? What I think of but due to the various contributions to the topic 9-5/engines/oil sludge cannot present.
