Battery Light is on - 2004 jetta

Hello! Check Fuse # 176 in the box above the battery...To be accurate, please tell me the engine size and model of your Jetta...Guru...Saailer

There should be a fuse between your battery and alt. If the fuse is blown, the current isnt getting back to the batt.

Something like this also happened to my brother in his Jetta, Im not saying its the same thing but his timing belt gave out.

WILL THE ENGINE START? IT SOUNDS LIKE THE BATTERY IS LOW OR THE BATTERY CABLES & TERMINALS NEED TO BE CLEANED. TAKE THE NEG. CABLE OFF FIRST THEN THE POSITIVE, CLEAN EVERYTHING TERMINALS & CABLES, PUT CABLES BACK ON BATTERY POS. FIRST, TIGHTEN IT. THEN DO THE NEGATIVE & TIGHTEN IT.

Open the hood. Lift the battery cover, then there is a little black box on top of the battery. Open it. bet it is burnt and melted. Do NOT take it to the dealership. You'll pay $600 . You need an alternator cable and a new fuse block. 30min fix.

Have VW check it out. I had just got my 04 GLI with 70,000 miles when the light came on. The thermostat triggered the light and so I had the whole timing belt, thermostat, and water pump service. Worth the money.

Must hookup computer scanner to obtain diagnostic codes. Problem must be repaired to keep light off.

SOUNDS LIKE THE CHIP ON THE KEY, IT CAUSES A CUT PROBLEM WHEN BATTERY IS DICONECTED OR DRAINED, CHECK ALL THE WIRES TO THE BATTERY TERMINALS MAKE SURE THERE ALL THERE AND NOT LOOSE. IF SO TIGHTEN THEM UP OR REPLACE THE TERMINALS.....

There are no known issues I know of. It is very hazardous to work on the SRS. I suggest you seek professional help with this problem.

It should only be dealt with not just certified mechanic but electronics expert at volkswagen itself. in this case i want to say, it needs Light Procedure reset! or priority reset. Mainly it is a code error in the jetta!

Hope it helps.

This should not be very difficult. Remove the back cover of the light. Twist the old bulb and pull out. Remove plug. plug new one in and twist into place. Replace cover.

The battery side is a very tight squeeze, you may need to remove the battery. But, I was able to do it by just taking off the battery cover.
