I was googling for some scenarios and came across this thread on another forum.. http://forums.whirlpool.net.au/forum....cfm?t=1857341

in short, guy takes his audi for service, dealer says the sump plug has been cross-threaded. All pervious services had been done at audi dealerships. Still audi washed their hands off the issue. Guy takes it to the courts but the courts says audi not at fault.

So if dealerships can get away from their own crap , then I got no chance of getting any warranty claim cos I used non nissan seat covers...
