general problems of the 2010 Volkswagen Touareg

My 2010 vw Touareg tdi 3. 0 have 2 service campaign 23r3 and 26k2 which is commonly known for vw tdi diesel scandal. I took my car to vw they said they will replace the catalytic converts and knox sensors. And the ad blue box. Today I got a call stating that my car will not get a catalytic converter that's epa compliant. And they can only do computer software and replce 2 glow plugs out of the 6 and that's cant be done before I replace a knox sensor which is the service campaign is for then when the check engine light is off I can take it back to vvw to replace the parts and program the computer. Or pay then $900 for that sensor.

I purchased this vehicle 3 days prior as a "certified pre-owned" from lakeland vw of florida. I was approaching an intersection and preparing to stop. As I rolled up and went to turn right, the vehicle suddenly lost power. Several attempts to restart were unsuccessful. We had to push the vehicle across a busy street, at which point I called roadside for a tow. The vw dealer told me today that it is my high pressure fuel pump, which seems to be a common failure for this vehicle.

While traveling approximately 75 mph on an interstate the vehicle suddenly lost power/turned off. There were no warning lights, no noises, no vibrations, no signs of anything. Vehicle had to be towed to vw dealer where I was informed that the high pressure fuel pump had failed allegedly due to substandard/contaminated diesel fuel. There was no sign of mis-fueling (no gas in tank when tested), contaminants are unknown. It seems that the hpfp is not designed to perform within the tolerances necessary to operate safely and reliably on 'pump fuel' available to consumers.
