Other Fuel System Pump problems of the 2009 Audi Q7

Fuel leaking top of left side fuel tank at fuel pump connections.

I have a 2009 Audi Q7 diesel bought from dealership March 2019 after it had been sold to the public once Audi did emissions recalls , after I bought this vehicle had issues with it 10 days after I bought it I took it back dealership wants to have nothing to do with helping me even though it still has an extended warranty for 4 years more from the manufacturer, I have a flashing glowplug and limp mode vehicle that when driving it and glow plug goes on while I am on the road vehicle slows down from going 65mph to approximately under 15mph in just seconds engine loses power and its a safety hazard while on the freeway . Audi dealer claims I have fuel contamination but when asked to prove to me this through fuel being sent to the lab they have no such lab results . They just claim I had this in order not to honor my warranty which is very fishy since I bought vehicle once they sold it out to the public after recall had been supposively fixed for emissions. I had fuel pumps replaced fuel pressure regulators and injectors as well all paid out of pocket vehicle still states code poo88 and code p0087 changed fuel filter also and now catalyc converter code is on also I feel they need to honor my warranty since fuel was never tested through a lab and its just by word of mouth that they claim I had contamination . Vehicle still being worked on but all costs out are out of my pocket eventhough my warranty booklet from the manufacturer states I should be covered for fuel rails, pumps, catalyc converte etc. .

According to Audi atlanta the high pressure fuel pump (hpfp) exploded. This small but contained explosion was centered within the high pressure fuel pump itself but then sent small metal fragments thorough the fuel system from diesel fuel tank through the injectors. Due to this 10k+ in parts and 4k+ in labor was required to flush the system, replace almost all of the parts in order to repair the damage.
