Hey everyone, bought a 2003 Jetta ALH last month and decided to start troubleshooting the battery drain problem. I have narrowed it down to the fuse box on top of the battery. If i disconnect it from the battery the battery does not drain. There are 2 wires that have a constant voltage drop across the fuse. They are the 2nd and 3rd fuses from the left. I circled them in white. I found a wiring diagram but it was to blurry to see specifics, im starting to think the ignition cylinder. Any helps appreciated, thanks!

Edit: it is just the 2nd wire from the left. The solid red thicker one.

First posts normally go in introductions else you could get a free fix and we never see you again!!!

Forum Rules and Guidelines


This is a new forum layout which is owned by a company last year that doesn't give a dam with loads of bugs which have been reported in the new thread. There is no TDI Wiki at the moment or original similes which they refuse to install. It doesn't show the car spec/location.

Add your car specs to your signature that will show on every post you make.

We Are Live - Community Feedback

This has been talked about many times.

I've made a poll which no one has posted in, there are a few votes and comments.

Do you like the new forum features?

Wiki pages have been restored as of 7th December, I asked where is the link it should be on top of the main forum.

ElsaWin doesn't show pictures on a 2003 Jetta.
