My 2004 330ci started running very rough and quit a few times so I had to get it towed into Schomp. I told them that it didn't seem to be getting any fuel and that the battery was cranking just fine...just no fuel getting to the motor. They checked it out and said it needed a new alternator. Seemed like an odd conclusion given the symptoms I described to them, but I figured they knew something that I didn't. So they changed the alternator for $1250 (and it took 5 days) and they said it was ready to pick up. Picked it up and drove off. 5 min later I'm having the same problem that I brought it in for, so I turned around and brought it back. This time they said it was a bad fuel pump. Well that makes sense, because it wasn't getting fuel, like I initially told them. They were happy to charge me another $900 for this fix. So basically I paid for an alternator that I didn't need. Also, they said they changed the spark plugs for free because it had the wrong plugs in it. Guess who changed the plugs last? Gold Star if you guessed Schomp BMW.

And just to update here...they replied to my review stating how concerning this was and to contact them or they would be in touch. This is for "show" on review sites only and appears to be their standard response to any negative review they receive. I contacted them and got no response nor did they try to contact me. The Garage in Parker is way better priced and they seem to have an idea of what they are doing.
