I agree with all the responses.

The terminology you quote, specifically "external force" is quite strange... is there a language issue here?

There is one "external force" here that might explain this issue: Rodent infestation. If this is the case, your car insurance will likely cover the repair under the "Comprehensive" coverage with often times a lower deductible. If this is true, ask BMW for an estimate that states this so you can submit to insurance and authorize the repairs..they should be OK with this.

If this is not the case, you need to collect up every shred of BMW paperwork and find a lemon law attorney. Try and find one that will minimize the % they take from your settlement- most will say "we only get paid when we win", which is true- BMW often pays the legal fees, but many also take a % off YOUR buyback amount. This varies by state, so LOOK UP NV LAWS using google.

You are getting the run around because once the dealer +BMW has determined the car was abused/modified/changed.etc, BMWNA will NOT overrule that decision. Even harder is a BMW regional rep has stepped in and altered the "independent dealer's finding'...

Who had possession when the problem became apparent is secondary to what the problem IS...and what CAUSED it.

More info needed....
