I had a penny stuck in the outlet under the climate controls... and I think mine was fuse #42 or something crazy. No more change goes in the cubby now!

Fuse 42 sounds kinda familiar for the later build date that I didn't research for my earlier post....................

My 2001 tdi 12v power plug in dashboard burned when unplug it, I change the fuse and plug in GPS, it works, but when I unplug it, the fuse burned. I checked there isnt anything in the hole, what might cause the problem?

My 03 wagon had a 30A fuse in spot #35 for the rear, and a 15A fuse for the cigarette lighter. (#35 was an icon of the book)

Wow, all three of my outlets were dead, a quick search on TDI Club brought me to this thread. I read that there could be a penny (or something) stuck in one of the outlets. As crazy as I thought this sounded... sure enough, a penny was stuck in the outlet in my coin cubby (by the way this was a pain to get out - TIP: small guage stiff wire with the tip bent at 90 degrees to pull it up enough to grab with needle nose pliers worked like a charm - it took me a while to figure this out). And then there was the crazy notion that the fuse box diagram in the manual was wrong... sure enough, it was wrong. The blown fuse was in 41 or 42 not 24 or 26. Workin' like a champ now.

Thanks a million to all of you on this thread!!

Yep it is definitely fuse 42 for the 12V power outlet! I too got a penny in the socket in the ash tray. I don't get why the manual that came with the car is so off when it comes to which fuse is which.

Along these same lines, has anyone re-wired these outlets to remain constantly hot? I have not had the time or motivation to date, but if anyone has done it I would love to hear your insight!

Exclamation do not over fuse

If the fuse blows when you disconnect the GPS, the cord may have a problem. my wife was using a splitter (to allow cell phone and gps at the same time) the splitter was shorting out, so blew the fuse. was a hit and miss thing. you can check continuity of the cord (or lack therof) with the cord disconnected if you have a meter. play with it and you may find an intermittent short.

do not use a larger fuse, unless you want some smoke and melted wires (sooner or later)

Which fuse is 42 it shows I don't have a 42. All three of my outlets are out but all the fuses show they are in working order.

Fuse 42 and all fuses are ok. Still no power. This has been out for years. The last few days my "headlamp out" light came on but all my lights are ok. I have decades of battles with car wiring that are making me paranoid here. So far there is no serious problems, but it all creeps me out good.

42 is the second from bottom row, third from rear fuse, the instrument fuse box, 20 amp (yellow). There's 2 fuse boxes, one in the engine and the one with the 12v outlets fuse: the driver side dash facing the door.

See "Here is the fusebox on a 2010 Jetta TDI" at the bottom. You have to scroll all the way to the bottom of the page.

Bringing back an older thread here...

All three 12v outlets in my 06 Jetta are dead. The sockets all look like brand new (did not find a lodged penny or dime from previous owner).

My 06 is a later build...the 20a fuse is in location #42, and the outlets are only powered when the ignition is turned on.

There is obviously a dead short as the 20a fuse blows instantly when I turn on the ignition. Checked the 12v sockets with my meter to confirm.

I've found a few threads in my searches where others have replaced fuses but the system was still dead. Unfortunately I couldn't find any threads that were updated with a solution.

I thought I'd post some info here in case anybody should run into this same problem in the future.

Issue is all three 12v cigarette lighter/charging sockets dead, and blowing 20a fuse instantly when the ignition is turned on. The Mk5 Jettas built in July 2006 and later had a Blocking Diode in this circuit, shown in the Bentley diagram as J29, between +12v and -12v. If this diode fails, like mine did, it can become a short to ground. Mine was blowing the 20a fuse instantly with a snap when the circuit was energized (ignition on).

This diode doesn't appear to be in the Jettas built in June of 2006 and earlier, according to the Bentley book at least.

If you happen to be looking for this diode, it is in heatshrink, in the console wiring harness, just next to the accelerator pedal. Might save you from tearing the whole car apart like I did.

If you're a keener and want to replace this diode, it is a 1N4002 DC. I removed it and dead-ended the wires for now and my 12v socket circuit is back to working properly. Just an FYI in case anybody is looking in the future.
