On around may 28th 2006- upon return from work that evening, the floor of my car was flooded- i was in total shock. i was about to go on vacation, i dried all the floor and aired it out etc. upon my return from vacation, it was worse than ever- the floor was again soaked, it in turn had damaged the computer system in my car and that in turn had caused the battery to drain. i had it towed to my mechanics shop- the following happened, the engine seized as a result of all the water that made its way into the car, and computer system totally destroyed. they drained at least 15 gallons of water from the car. this is incredible and unbelievable. the mechanic said the car was clogged and even he had a hard time accessing, and i as owner had no way of finding out. i bought the car in 05, it is an a6 3.0 year 2002. with around 54 thousand miles up, and i had only put 1000 miles up on the car. the warranty - extended, said in turn the car is not covered due to motor damage, and a new engine would cost $8700 not to mention the mechanic fees. upon further investigation online, i see that there are several reports of this problem with this year audi and other years and vw passats also. i paid nearly $26000 for this car and feel i have been scamed by audi, major automotive who sold me the car and the gm protection plan who provides the extended warranty, - the sales person advised it was bumper to bumper coverage- i now find out that i have to pay for my new engine?? i feel all parties should be held responsible and want to know if anyones is filing a class action law or doing anything about this, where is the protection for the consumer, please help me, i am not rich, i spent all my savings for this car, i am currently paying insurance and also car payments on this car, i cant afford a new engine, even if i could is the same problem going to arise again. please help me. thank you, e. morrissey (there is not a selection for audi under vehicle. *jb
