Engine Belts And Pulleys problems of the 2002 Audi A6

My engine failed while driving at 35 mph on route 375 in woodstock, NY. The failure was a result of assembly bolts on the reverse side of the exhaust cam shaft variable valve timing sprocket loosening and falling out against the cylinder head, stalling the the camshaft and breaking the timing belt. Inspection of bolts show neither a lock washer or thread lock adhesive were present to prevent the loosening due to heating and cooling or vibration. Further service of bolts cannot be performed as there are no tightening specification for these bolts. An easy fix for this mechanical failure would be to remove both valve covers and replace the bolts on the timing gear sprockets with new bolts with adhesive on the threads. This is an interference engine, which results in a catastrophic failure in the bending of valves and total engine destruction.

Audi A6 3. 0 2005 68,000 mi. Premature water pump failure premature timing belt failure as I was pulling into a shopping center parking spot on 4/25/05, the car began to feel different and the power steering was not working. I shut car off immediately and it was steaming. I turned key on again without starting engine in order to check guages. There was no indication of overheating. Outside the car the coolant had leaked onto the ground. I had it towed by flatbed to winner Audi in wilmington, DE. They diagnosed that water pump failed and resulted in timing belt failure, also. Quoted $2380. 00 to repair the timing belt and water pump. Once this is completed, further diagnostics are required to determine if more damage exists. Service advisor, michelle suggested I call Audi for assistance. She said that sometimes they will agree to have the repair done for the customer at the warranty rate, which is half the regular rate. I contacted Audi America customer relations @ 800-822-2834 for assistance. Willie moore took my information and indicated that even though the vehicle was out of warranty, he would review the problem with the dealer for possible assistance with my repair. After putting me off twice, saying that "the department was closed for a few days" each time, he finally called me with an answer after 8 days. The answer was that since the vehicle was out of warranty, Audi would not assist me in any way. I could not help but wonder, why put me through 8 days of waiting and false hope if the answer was as simple as that! all of us knew from the start that the car was out of warranty!.
