FRAUDULENT SERVICE! Be WARNED! Audi Peoria has a dishonest and fraudulent service department! I spoke to a "Jesse" who quoted me $440 to replace a single HID headlight bulb for my Audi A4. When I asked how much the bulb was he said:"$200, then $240 for additional parts and labor, and $800 for two because they have to be replaced in pairs."
This HID bulb is selling on Amazon for $82.99; thanks to YouTube I did it myself. It took less than 10 minutes. It was so easy, my 8-year-old niece learned how to do it. Wal-Mart sells the parts you need to unscrew the left headlight casing from the frame. T25 bit plus extender = $14.99. $440 - $97.98 = $342.02 savings.
Their 5 stars reviewers are suspicious; I doubt I'm the only customer they've tried this on. Cons.
