My '14 328d had the diesel pump failure at 41k. Factory warranty covered the entire repair (fuel tank, pump, lines, injectors, labor, etc.) Likely culprit was contaminated diesel. As described, the HPFP disintegrates internally and gets metal bits throughout. Now at 89k, no problem since. I did not receive the Letter offering 10 yrs/120k protection, I will try

I did receive a letter dated December 2018 for:
"Bolts for the electric motor of the power steering gear".
Same extension offered 10 yrs/ 120k
