A3 TDI 270 miles new, broke down.
Bought a new A3 tdi and at mile 270 broke down in the middle of the highway. The car stalled and shut off, thank God no other cars were near. I had the car 2 days and it broke down, apparently the fuel pump and fuel module were causing a short. Fast forward to mile 2,000 plus and the car stalled and this time not as lucky as I was hit hard ending up in the hospital with bumps and bruises. Called audi care and promised to get back to me in 4 days because of the holidays. Anyone else having this issue?
You do not mention the actual codes. The original NHTSA complaint on the so called HPFP (Bosch, sub vendor) issue had a less than 1/3 of one percent incident/incidence rate (the included population, aka, 800 cases app 241,000) . The NHTSA closed out the original study. http://www.detroitnews.com/story/business/autos/foreign/2015/03/31/us-closes-probe-diesel-vw-vehicles/70713086/
(TMI… SAFETY did not appear to be an issue) I would surmise this (your) incident should be reported to the NHTSA . BUT that is up to you.
First of all, get the car looked @ by the dealer, as (2.) you suspect the contributing cause (HPFP ?) falls under warranty and periods AND (3.) the faults were not fixed correctly the first time (causing/contributing to/ safety issue). (4.) Get Audi USA in the loop also. (5.) Another would be to let them (Audi USA/dealer) handle the (warranty AND CRASH) repairs. As a minimum, upshot. I would want a new car.
Six, get a good auto personal injury attorney. They can coordinate the various issues ( lemon laws, new car, injuries, etc), or @ the minimum give you legal advice about actions and remedies.
