I thought I would post this.... because the fuses thing has driven me crazy.... so I hope this helps.

as we all know, VAG cars are mostly designed by Germans... and given this is an english mainly site.... this might help.

German is what I call a lego language... the words look big because they just click separate words together, like lego, which makes new ones...and by knowing each separate word.... you can usually work out the new meaning, if they aren't just simply the logical two words as separate in English.... for eg.... Wasserkocher.... or wasser kocher, which is water cooker..... or kettle.

A "fuse" in German is a "Sicherung"

A carrier is a is a "träger", so "Sicherungs träger".... or...Sicherungsträger so, fuse carrier.

A holder is a "halter", so "Sicherungs halter" or "Sicherungshalter...., is a fuse holder.... or fuse box.

So the box holds the carriers, and the carriers hold the fuses.

Audi names each holder or box as we usually say.... A, B, F.... etc

So you end up with Sicherungshalter A, B, F..... so SA, SB, SF, and Sicherungsträger 1, 2, 3 so ST1, ST2, ST3... which is already inconsistent... right...? Why not SHA (Sicherungs halter), SHB, SHF, as with ST1 (Sicherungs träger), ST2...?

now... for some reason, they put the number of the fuse, after the box when constructing the acronym rather than after the carrier in which the fuse resides... so If I was to describe the fuse in fuse box F in carrier 3, position 3....it would look like.... "ST3, SF3".... crazy....= "Fuser carrier 3...ST3", "Fuse Box F, Fuse number 3, SF3"

And to make matters worse.... there are letters (C,D,E, F...) near each fuse carrier (pic below, with purple in it)... confusing me no end... (forget these letters, they may mean something.... but I didn't need them or find any reference to them when locating a fuse).

They also don't reference the fuse box letter in their diagrams (see green pic below), the letter is in the title of the section above... so the picture doesn't help you know which fuse box it is by itself, you need the whole document to scroll up to the section heading and find... SB, SF or whatever....

JHC!

Anyway... I probably won't remember this by the time the next thing needs fixing... so it's as much for me as for you all.... enjoy :)

I am sure that all made sense at some point in someone's brain 30 years ago, when they only had 3 fuses :D

They drive me mad, the ToeRag 2 we have just been doing a parking system fault on has more fuse boxes than a 747! Add to that the lovely little trick VW do with the ToeRag 2. With say a Passat type 3C, SA is the strip along the front of the engine bay electronics, SB are the fuses on top, SC is on the dash right, SD on the left and this doesn't change for right or left hand drive, except with the Toerag! So when searching for sy the air suspension fuse, you get the wrong side!
