The base module has about 4 fuses. They are the standard AC Delco-type, plastic, flat fuses (I think 10 amp) and can be found at Autozone. The Mercedes parts catalog at the dealer doesn't even show them. They are really easy to access since they are right on top. I talked to an MB shop forman last week and he said that he has seen these fuses go out many times.

Oy, my head hurts....

p/n 011 545 97 32, as listed by Myarmar, is available from a parts yard I found which specializes in MB parts. I went to double-check it on my car, however, and found mine to have p/n 009 545 91 32 instead. Called them back and they told me they do not have one by that p/n, and in fact that p/n didn't even come up in their database. So.....

Anyone know if these two part numbers interchange? Not having the car fixed is killing me!

Thanks, checked that, all fuses were good!

That p/n is for Euro 500E and 400E

Which p/n, the one you referenced, or the one on my car? If it's the one on my car, wonder how I ended up with a euro one? Mine seems to be an U.S. model, or perhaps I just assumed that...

Will they interchange?

Thanks SO much for the help!

You need to find a reasonably competent dealer parts person - they'll be able to answer your question definitively in a matter of minutes.

Yes, p/n 009 545 91 32 listed in my EPC for 500e and 400e, but "not relevant to MBUSA"
I don't know about interchange.

Hi all,

My theory was correct! A replacement Basic Module fixed my weird electronic gremlins, she's good as new now! Since the p/n I had in my car didn't match what ANYONE thought I should have and appeared to be not even for a U.S.-spec car, I went with p/n 011 545 97 32 as suggested. It has 4 fuses under the cover, vs. 3 fuses in the one that came from my car. (The weird p/n module had been working perfectly in my car for however long it had been in there, up until a few months ago.) I plugged in the replacement, cranked 'er up, and VOILA!!! All systems are go!

I would like to kiss and hug every one of you that has offered help and advice through this frustration! However, I do not have enough frequent-flyer miles at this time.

Thanks again, guys, you ROCK!!!

Good to know this module works fine. I checked and my 92 500E also has the same p/n 009 545 91 32, but it works fine. It maybe not euro, just old and replaced part. What kind of problems did you have with it?
Thanks,
Mike
