I've done this 3, three, did I say THREE times[xx(] I had the same symptoms the first and second time. I use a #10 allen socket with a #10 box end rachet wrench on it to turn it. This is for the upper allen. For the bottom I use a standard "L" shaped allen with a box end on it as kind of a breaker bar to loosen it up. The last time I did it I got an estimate from the local indy MB mechanic. He wanted $450, 2 hrs labor @$75 and $300 for the starter. I bought one on line about $100, rebuilt Bosch, free delivery and I had a coupon. I timed my self and it took me 50 minutes, but then I've done it 3 times, three. The first time because the one that was in it when I got the car was a non turbo and was dying. The second because the first rebuilt bosch was a bad one[xx(] and the third three years later, all on the same car.[8D]
The first time was the worst[xx(] a real b&%#ch[
] but I did save a lot of $$$$
