when a battery is completely drained, it shortens the life or could kill it all together. Time for a new one. Doesn't need to be coded.

Check you transmission filter.

Please check engine grounding and try direct start from starter.. maybe swicth worn out.

My bmw dealer said that the Mass Air Flow Sensor needed to be replaced. The car would not run. It will start, idle. upon excelleration it chokes and dies. The "check engine" light is on. I disconnected the MAS and the car runs fantastic. SOOOO, I ordered a MAS and installed it. Reconnected the unit and the same problem occured. Is there a fuse relay under the hood or back seat that I can replace?
Thanks
Gordon

starter may have came loose.. try tightening starter bolts.

If your getting no fire at the coil. that's why you're not getting fire to your plugs and therefore it won't start. Change out your coil. This should fix the problem.

ebay is the best place to try and find this.

havent sorted it yet getting a bmw mechanic to check it out will post back with solution he's comeing next week
