Gilly,
Yes, I straight wired the burnt-out diode and I was hoping to order the 210-540-55-33 kit to replace it. But alas the dealer wants $129 for the kit.

Do you know what this kit contains? The parts guy does not have the diagram/picture, just price. I am kinda shy to pay $129 for a straight wire with a diode in the middle or is this my rude welcome to MB repair world. Well, she's (E320) been a good gal this far!!

Any hints?
