1 star is too many.
I had the unpleasant misfortune of dealing with these guys just last friday. I had just installed a new fuel pump in my older bmw, and it didn't solve the problem. The fuel pump was obviously straining to push the fuel, as was the one I took out.
I knew the next step would be to use a pressure gauge to check the lines. But I'm from out of town so I didn't have my tools. I'm not a great mechanic, but I do a lot on my own.
So i get there, and agree to the 80$ diagnostic fee, hoping they'll be able to track down either a clog in the fuel line from the rail, or an air leak in the fuel line from the fuel tank.
They come back that I bought a bad fuel pump. I told them, I doubt it, it's brand new, and the same problem, and ask them what they did to come to that conclusion.
The only thing they did in an hour, to ""diagnose"" the problem, was check the fuel pressure at the rail, and see that it's 0.
IT TOOK THEM AN HOUR, AND THEY CHARGED ME 88$ (with tax) TO UNSCREW AND RE-SCREW A SINGLE SCREW.
I say, ""well did you check the voltage?"" no, of course they didn't.. he has his dude do it.. comes back 2 minutes later.. voltage is fine. Then they look up stuff on the computer, and give me bad information, saying it only has one fuel pump, when I know for a fact that it has an in tank pump as well. Then they say that they'll have to remove the gas tank to get to the in tank filter, also bull because i'd taken out the in-tank pump and filter earlier that day through the hole in the rear seat.
At this point I suggest them testing the pressure at other points in the line, but they say that they can't do it any more because the first hour is already up. What kind of a mechanic takes an hour to check the fuel pressure at one point. I should have just bought a cheap pressure gauge myself. These guys are either horrible at what they do, or professional con artists.
Also, while in their waiting room, I hear them overcharging people to the tune of thousands of dollars for minimal AC work, and other wild claims.
I should have known just by the fast talking nature of the guy at the desk that they care nothing about helping people with their cars, and only about finding a way to make as much money as they can.
Do yourself a favor and go ANYWHERE ELSE.
