  1. Chances the HPFP was changed under warranty so the only thing to worry about in these cars in the long run is carbon build up due to the direct injection but other than that they're awesome. That's why I'm not sold on direct injection because whatever fuel costs you save will go towards getting the carbon cleaned out every 2 years so you really save nothing but the companies will market it differently.

  2. I think Audi is using both the port and direct injection method in their FSI motors so the intake valve gets washed with fuel. The new DI motors in the MBs are too new to have issues so time will tell. Right now your best bet would be to go with an MB with the older M272 unit, smooth as silk and bulletproof reliable except the early build ones.
