Oil Change-now need new motor - checking for cause

This is a follow up from a discussion question I posted over a week ago. I am wanting to know if there is anything Auto Express could have done besides not put oil in my car or put a faulty oil filter in that could have led to the oil not circulating i.e. no oil pressure that the dealer can check for without doing major exploratory expensive searching. I want to determine if they are at fault or not so I can pursue it or let it go. Right now the dealer isn’t too keen to help me try to determine the cause but I thought if I had some specifics to ask them to check they might be more willing. Can anyone advise me on this? I am grateful to all of you who responded last time. (2002 Jetta TDI)
