User Error: Or, Why Audis Are Always So Expensive To Fix

CarScoop found this discussion on Audi Forums in which a member by the name of Powrd1.8 supposedly decided to try a DIY port-and-polish that involved dumping a 25-pound bag of sandblasting sand into his intake—while the car was running. (You’ve gotta read the guy’s original post on this—it’s just priceless). The results were as expected—after going through about half the bag, the motor started kicking and bucking and sounding "really weird"—and the Audi people on the forum are completely beside themselves. They ultimately agreed that it had to be a hoax, but in the meantime they’ve been giving the guy some pretty stellar advice to address his problems, such as:

"Better add some water to the crank case to thin some of that sand out first."

"Sand is like synthetic oil. Once you start using sand, you just can’t get the same performance any more from pure filtered air."

and

"Don’t reproduce."

If it’s a joke, it’s a good one. Though it’s kind of hard to believe that someone would actually try anything this dumb. Heard of any similar gaffes?
