I am about 30 minutes away...I think there are some members even closer. If your friend is a DIY'er I could probably help out some but I don't "tear them down to the pistons" (anymore). I'm sure there is someone closer too but I'd be happy to lend any assistance I can. I have owned two 240D's, a 115 and a 123 so I know them both pretty well.
