I think it will be easier than the last poster said. Starters are a pain on the 300's compared to your 220D. If you can get it out the top, get it out and take it to a local auto electric shop and they'll rebuild it cheaper than a Bosch rebuilt will cost. About the allen, his is an allen bolt and on the SDL it's a regular bolt. It all depends on the model. I wouldn't doubt if yours is an allen, in that case you really need to clean it out well to get a good grip. I need to do the starter on my SDL this week, which they are very easy on those.

Thanks
David
