general problems of the 2004 Volkswagen Jetta

I hit a pot hole with my 2004 vw Jetta tdi (I bought this car brand new and it has never been in an accident). When I turned the corner I heard a "popping" sound. Drove it to a nearby mechanic. The closet vw dealer is 70 miles away. The spring on the driver side was broken. The mechanic said that this is a manufactures defect as he has never seen a spring break like that. There was erosion in the spring. I still have the spring. Replaced at $347. Contacted the vw dealership. They first tried to brush me off saying they didn't see the pot hole etc. Eventually they gave me the vw headoffice phone #. Brushed off there too as it's out of warranty. It's not the warranty. It's a faulty spring that was placed in my car. It also ruined the shock.

I was driving home 50-55 mph clear night smooth road I had not noticed any signs of my tire being low I have valve caps that show when tire air pressure is low and they all were green than I heard a loud noise and my car pulled to the left I pulled over and noticed my tire had completely separated at the sidewall leaving about 2-3 inches of tire on the rim and the rest was in one piece barley sitting on the rim the tire was made by nankang toursport 611 dot 109n other numbers I found on the tire were 517 2306 z2c, n-2570-3l xr611 radial 195/65 r15 9ih m+s tubeless when the tire blew out and the tire separated it tore my abs sensor wire and im not sure what other damage my alignment is now off as well.
