Tony, since most or many of the BCM fires seem to start while the car is parked and stationary, it doesn't follow that in those cases it's the alternator causing the fires.

...The dual pulley that costs $710 from Mercedes also was bad, but the shop guys pulled a favor owed and got a brand new Mercedes original one for $300. Then the harmonic balancer (crank pulley) retails over $700 from Mercedes but I spent an hour looking everywhere online and got one for under $500 from an actual Mercedes dealer somewhere. Those have a molded rubber piece that wears out over a bunch a years. LoL
Sounds like you overpaid. But, prices change all the time. The person I bought my 2004 SL500 from had just had a B Service done and they came back with another $10,000 in recommended repairs. That's when she decided to sell. I bought it from her for $10,000 and spent about $1500 on all the recommended repairs, most of which I found were unnecessary. One recommended repair, based only on the age (13 years at the time) and mileage (50,000 miles), was to replace the water pump and idler pulley. The Mercedes tech had perceived a little play in the idler pulley. I replaced both and found them to be in perfect working order. My friend had always had the car serviced at the dealership and they treated her like a queen -- of course, they also saw her as a "cash cow". The spark plugs are iridium, which normally are good for 100,000 miles, but Mercedes recommends changing them at 65,000 miles (or thereabouts). Of course, two plugs per cylinder and the labor involved made that recommendation very lucrative for the dealership. Some things, usually involving fluids, you want to stick to religiously. Other things, maybe not so devoutly.

What is your actual model designation? Should be something like 230XXX. Put your VIN into www.lastvin.com to get the info.

Dual pulley is only used on SL55, it lists for $720, SL55 crank pulley/balancer lists for $675. AMG specific parts are expensive.

Wow, this thread has become a life of it's own. GREAT, that's what I like to see. Insight/information/knowledge to share with everyone else. I'll tell you this, and I found it to be quite frustrating, while I was a member of a BMW forum, I NEVER received the type of, and I'm going to be cheesy here, the brotherhood among the members of the MBZ community and I have only been here for just short of two months whereas I was on the other forum for over eight years. Go figure, right?
I truly thank you all.
