Protagonist,
Check out this thread on B-van forum for similar starter fuse issue.

http://www.classbforum.com/phpBB2/vi...?t=3220#p21525

Also get the MB letter from this web page and give it to your dealer. That starter fuse should be 25 amp like mine.

It's getting even more interesting. I'll just wish you long distance luck.

Whatever it turns out to be if one of you Interstate'ers could look at Maggie's model info on her rig and see if same issue might apply to her. We sure don't want to see Maggie in a similar spot.

Good luck.

I agree. Good to know. I just replaced the factory installed 20 amp fuse with a 25 amp just in case (my fuse was in the drivers footwell, 2013 AI on a 2012 chassis).

The factory's tell us never replace a fuse with a bigger fuse.....

And then they go and do this....

A guess might be that there is some kind of an unforeseen back feed popping those fuses...

Hmmm, I wouldn't have changed mine so quickly, but the letter to Sprinter Dealers looked official at first glance. But in re-reading the letter, I now have reservations. The letter was written very sloppily (department's vs. departments, their vs. there, and other grammatical errors) and reads as if it was written by a customer about a personal vehicle. Or is this the way Mercedes writes internal memos?

Just checked my 2010 Sprinter manual and it specifies 20A. Will check w/ my MB Sprinter guy to verify if 25A is the new preference.

Trust but verify.

It's apparently bogus. I asked the service manager at Mercedes Benz of Baton Rouge. 2011 Sprinters came with a 15amp starter fuse and the service bulletin called for replacing it with a 20amp fuse, not a 25amp fuse. Later model years came from the factory with a 20amp fuse already in place. The service manager said he had never seen a bulletin calling for increasing the fuse to 25amps.

Oh, and the reason why the fuse blew on mine, one of the wires was chafing on a piece of metal (he didn't say which or where) and rubbed off the insulation. Wire replaced and properly sheathed in a plastic tube to prevent future chafing, problem solved.

And more good news, no apparent harm from the improper towing method. Some metal particles in the transmission fluid, but typical size and quantity for having over 18,000 miles on it; no indication of unusual wear, fluid level normal, no leaks at the seals, no discoloration due to overheating. He used a pump down the dipstick tube to take a sample for analysis. Recommendation from the service manager, wait until the 20,000 mile service, and drain/replace the fluid then.

I get to pick up my Interstate after work tomorrow, and I can finally recover from my separation anxiety.

Did he show you where the tranny dipstick tube is? I couldn't find it on mine and dealer said there isn't one. I did see an add-on kit on the 'net tho.

Glad to hear it turned out to not be a big deal after all you went thru Pro. Also it was good of your dealer to comp the new battery.

Well, FWIW, according to the 2013 Fuse Allocation Supplement, fuse 28 is spec'd at 25amps.

In any event, glad you are back in business. Quite the story!

My 2012 Sprinter came with a 25 amp starter fuse from the factory. It was built in August 2012.

That MB letter/memo is not a service bulletin so it's not really official MB engineering data. To me it looks like a note from a regional service manager. Bogus or not I'm glad they found the source of Protagonist's problem.

He hasn't shown me yet, since I won't actually be returning to the dealer to pick it up until tomorrow after work.
