I have a 2004 bmw 745i. from time to time when it was really cold, my car would shake heavily when I first start it and when in idle, I would sometimes get a engine malfunction drive moderately warning, but it would go away when I would began to drive. I thought it was the oil because I had a slow leak. The other morning I was driving on the highway and the engine malfunction drive moderately light came on suddenly while I was driving and the car started so slow down and eventually cut off. Tried to restart it and it will not, and hasnt start up since. The mechanic my AAA towed it to, was not a bmw mechanic.. He said that he was pretty sure I need a new engine but wanted to charge me $600 just to do a compression test. The fault codes that came back are. 2761, 2760, 274E, 273D, 2738, 2743, 2748, 2749, 2746, 2746, 278A. From what I read these codes could come for , fuel pump, spark plugs, or the coil package. Can someone please help? don't want to replace the engine if I don't have to. thx

If it's running rough, chances are that it's misfiring. If the Check Engine light is flashing/blinking, it is definitely misfiring.
If that's the case, drive it as little as possible... Or straight to the mechanic because the more you drive it while it's misfiring, the higher the chance is of you ruining your catalytic converter.
