MB dealer tells me the large supercharger bearing bolt and washer are missing from my vehicle. Not sure how that is possible or why the bearing assembly never came off, but here's the problem: The bolt and washer are not available through MB alone. The only fix the dealer could offer is if I buy the entire bearing assembly for $1700. If anyone has a bolt and washer laying around, please let me know. The bolt and washer appear in pictures I've seen to be dark colored with a 17mm hex head. Thanks in advance. PJ
