data for 3037 repaired fuel pumps Oct 2011 - Oct 2012
I'm still not sure I understand what these data exactly are. They should be inclusive, but are clearly not.
Anyways, some more plots from file INRD-EA11003-54335P.xlsx, which has the warranty data (?) for 3037 replaced/repaired fuel pumps.
Repair date:
So clearly cases keep piling up until the end of reporting period.
Repair mileage:
Amusing tidbit: From browsing through document 54326P.pdf, it seems at some point VW took a bunch of original high pressure fuel pumps, returned them to Germany, and put them without modification into cars for the German market. The US then got improved pumps.
I still haven't figured out how VW decides whether a pump failure is Bosch's fault, or due to bad or wrong fuel. I'm afraid the documents of March 30, 2012 that might contain that information, and info on regional and seasonal breakdown, plus comparison with other countries, were declared confidential and are not posted by the NHTSA. If somebody has found this info, please post it here (even if it is a repeat post - I can not possibly read all 6000 previous posts). These should be 'Request 32' data, points f) (adjusted rates per 1000 vehicles), g) (geographic breakdown), h) (seasonal), i) (country comparison). The NHTSA clearly asked for them.
