HPFP Ethanol link?!!?? Automakers suing to stop Ethanol fuel addons.

I own an '07 335i and am dreading the HPFP failure. Currently on 16K miles w/ no HPFP failure. (Knock on wood)
From what I've read some N55s also seem to be creeping up w/ similar HPFP failures.

I came across this article which adds to the current speculation that Ethanol may be a culprit behind these infamous HPFP failures.

"According to a press release

The petition challenges the ability of EPA to grant a partial waiver for three specific reasons.

* The Clean Air Act does not authorize EPA to issue any “partial waiver” decisions,
* EPA’s own statute passed by Congress in 2007 states that fuels can’t be approved for the market that could cause any failures. Yet, E-15 has been shown to adversely affect engines in non-road products and later model year vehicles, cause emission failures and increase air pollution due to misfueling. Further, administrative records fail to demonstrate that even new model year motor vehicles (other than “flexible fuel vehicles”) would not be damaged and result in failures when run on E-15, and
* The testing, upon which EPA made its decision, was put in the administrative record too late to permit meaningful comment or scrutiny from concerned groups and stakeholders.
