general problems of the 2009 Audi Q7

I was driving my 2009 Audi Q7 last June 27,2021 at 5 pm in interstate 5n my speed is 70mph when I heard a beep sound , air bag and hood light on flashes in the dash board and I decided to pull over on the shoulder lane when my wife noticed that smoke coming out in front of the engine, I stopped the engine but I can`t pull the key and my set belt locked to where I can`t release it , my wife help me to get out from the set belt and she managed gave forced to her door just to open it , I was able to reached the lever to open the hood where smoke & fire coming out from the engine , I`m trying to control the fire but fire spread out rapidly inside the car and less than a minute fire covered the entire body of Audi Q7. I can send the pictures if needed or upon request. . .

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. .
