These guys are a rip-off! I took my Porsche Cayenne in because I was having trouble with my headlights. Turns out it was a ballast or control unit issue, and they had to be replaced, the price they quoted me for parts was the same as if I had gone to dealership service department, but then they got really stupid, they quoted me 3.5 hours of labor to do the job, almost $600.00, when the job literally takes less than 15 minutes, yes, I said 15 minutes! Total! For both ballasts, the ballasts are attached to the back of the headlight unit housing, the housing comes off with 1 turn of an allen wrench type tool located with tools provided by factory, then 1 clamp that just pops off, and 5 screws and 1 plug, that's it, it's a plug and play deal, the whole job is easier and faster than replacing air filter! I've heard of businesses suing because of bad reviews, I hope these guys try that with me, I would love to have the judge watch me change out the parts in 15 minutes or less. And when I refused to do the job there, I was charged a $175.00 diagnostic fee, just so that they could plug a scanner in and get an error code.
