An interim design mod will be to integrate a fairly high volume filter (not the piddly little one now) in the HPFP housing at the HP exit line, using the pressure differential to trigger a shut down and confine damage to pump.
That plus a return line filter.
Then metal particles are confined.
Bosch has to know all of this, their upper management or Board of Directors just don't give a sh*t. 4 years with this pump,on VW's and Audis, and they still have not addressed the engineering problems and material problems it presents. Their idea of making 3 changes to make the pump more "robust" on their idea of "substandard" fuel has failed. 2011's and 2012 VW's still grenade HPFP's.
I believe in the USA, you need to design product that is "fit for market". I don't see Bosch meeting that requirement, when they've known since 2002 what low lubricity fuel does to their pumps and they know the ASTM standards here for D975 and testing.
The flaw in their current design is using fuel for purposes other than fuel, for lubrication.
