Message They have made improvements, and they've also extended the warranty on the pump to 10 years.

One of the workarounds they came up with which seems to work was an eprom flash that changed something in the priming sequence of the low and high pressure pumps. That avoids or minimizes cavitation which was believed to be at the heart of the issue with the HPFPs.

My 2009 335i is still running on its original pump, no issues.
