If you're doing work under the car, you could jack up the transmission a little and that will give you room to put a vise grip on it and try to get it out that way. But if you jack, you will need to remove cooling fan so it doesn't hit the radiator.
Thanks for the advice. I'll try that as soon as I get home from work today.

sorry bring a old post back from the dead. I'm working on replacing my starter and I got the one bolt out from behind the engine. The other bolt is starting to get stripped. I got the bolt out sockets but haven't used them yet. Dose anyone have any ideas on getting this bolt out?

Default stupid engineering for sure

I'm embarrassed for BMW engineers. There is no reason for this being engineered this way. To change a starter, you have to disassemble the lower end on the engine, disconnect the transmission remove the exhaust, pull everything out of the the engine bay above the motor, remove intake manifod and even then the ridiculous torq E12 bolt heads will not break lose with a 4 foot schedule 80 1.5 inch outside diameter just bends after flooding the entire area with penetrating oil.
I thought Porsche engineers spent too much time inserting things where they don't belong. BMW engineers have their heads inserted in the same place. This will be my last M3 for sure, there are so many well engineered cars out there it is easy to see why BMW as a company has been lost for so many years with little to no chance of ever being relevant again.

You have to remove the fuel tank too...and all 5 wheels.

Is replacing the starter really this involved? Or are people taking unnecessary steps to remove theirs?

It's not bad if you have the right tools. I can get it off in less than ten minutes but I don't have the stock house clamps on the manifold. The most difficult part is loosening the bolts holding the starter. Craftsman makes some bendable ratcheting wrenches that make it less painful.

Here is a solid DIY. I just did this a couple of days ago and the video details every step of doing this above the car. The 2 bolts to get to are a PITA but doable with the right tool.

Its not that hard but if the bolt head strip your in a lot of trouble.
Especially if its the upper of the two.

You dont need to do anything from the underside. Its all done from above.
If you have the correct tools for removing and refitting the intake manifold clamps your going to be alot faster.

There is a little bast1ard of a coolant hose that is very sensitive to being moved and it will leak so i would advise buying a spare 64216902680

I rounded the lower of the two bolts and I had to go in with a little die grinder and small cutting disc and take the head off of it. Ground it flat to the gearbox and then was able to pull it straight out. Took me 4-5 hours
