Fuse size

mecheng77 · 10-11-2019, 06:42 PM

Does anybody know what type of fuses are the very small ones behind the glove box? Mini, micro? Thks

Never had a fuse issue with mine, but my guess is that the JB fuse panel has (1) Maxi, (2) Standard ATO, and (3) Mini fuses. I would suggest pulling one and comparing with the diagram in this Wikipedia link, to see if the small ones are Mini or Micro2:

Are you "out of spares" on the top row?

They are mini.

And if your wondering where the spare mini 20a fuse, it's circled in Red, I guess they ran out of room on the top row. (I removed in, for this pic)

I looked at the chart and nothing is indicated in this spot and all the 20a fuses are accounted for so I'm 99.9% sure it's a spare. I swapped out the 57 fuse for a 20a. A hole mechanic who changed the junction box under warrantee took the fuse puller and some extra fuses.

Sorry to revive an old thread but they're ALL mini? Just making sure. Doubt it makes a difference but I have an '11 325i LCi with an N52B25.

No there is also standard size and much larger ones as well

When I replaced the front door lock actuators the TSB also says to replace the 15 amp fuse with a 20 amp. That was what I did -- Mini fuse 20 amp.

I did not think I saw spare ones, but anyway, I used one from this package. Now I still have 4 spares.

Why does BMW give you a cheap flashlight in the glove compartment like this? They could have picked decent ones from Harbor Freight. Can this thing be drawing down the battery while parked I wonder?
