Well, then I must be wrong and all the complaints about the dealerships are unfounded, since they happily fix every design flaw at their expense.
Actually, ILUVMILS said it himself. Only after the main office acknowledged and published a fix, it was repaired (although we don't know if it was completely free of charge). If main office wouldn't have done that, the noise would still be there.

Just an example, out of over 1000 reported bad wiring harnesses on the M104, there is just one case I know of that had been repaired at the dealers expense. Not even repaired, but the cost of the part was paid for by the dealer.
The rest of them were paid for by the customer / owner! And who knows how many bad harnesses are still out there.

Lets face it, nobody is starting a business just to exchange money or even give some away. But, if a flaw in design is detected, the least one could expect is an admittance.
The whole setup is so complex that nobody can be blamed for anything.
There is an exception of course. "Warranty" every new car owner hopes that something break's during that period.
