Failures in VW have run the gamut from under 600 miles, to 1800 miles to 14000 miles for a 2011, to an 85,000 mile failure down in Texas last August, to a 105k mile failure in San Bernadino county, Calif last October. There is no predictability as to failure on the mileage for MTBF, there seems to be clusters, statistically, shortly after the hottest months of the season. CAlif, TX and FL are the record holders for most amounts of failures, of folks that have reported to TDIclub their failures. Lots of them start showing up in late August, Sept, and October, the damage probably starting the cascading effect sometime during the hot summer months, or vacation driving.
I can not stress enough to leave a good amount of reserve fuel in your tanks during hot summer and fall periods, it is indeed coolant for your fuel system.
Many have noted that even running the new 2012 passat tdi down on fuel, until the fill up light indicates you are now in reserve, still yields only 14.5 to 15 gallon fillups on an 18.5 gallon tank. This is unprecedented in TDI build history. No other common rail VW TDI seems to use so much of the tanks capacity of fuel as a reserve, in the North American Market. Also, failures among Northern Tier US states seems to statistically lower, much lower, the amount of failures per car units sold. California is the leader in killed Bosch HPFP failures, in part because of so many drivers, long distances, desert heat, and non existent public transportation options, as well as huge population at 38 million people, with distances being long, it is a long, skinny, narrow state.
