Volkswagen Jetta owners have reported 29 problems related to alternator/generator/regulator (under the electrical system category).
The day before the car quit, it would not start after being parked in the mall parking lot. A battery pack got it started, and it was driven home, with the thought that it needed a new battery. The following day, it was being driven to the local sears, for a replacement battery, when the abs and airbag lights came on. 30 seconds later lots of warning lights came on, and the car sputtered and stopped dead in the lane of travel. It would not turn over, and power accessories would not work. I was stopped on a very busy 2 lane back road, with no shoulders or side streets, uphill, on a blind hill. After 1 1/2 hours of white-knuckle directing traffic, and calls my auto club, and the local police; a local police officer, and a local tow truck showed up and gave me a lift to my repair shop. The mechanic's diagnosis of the problem was a partially melted fuse pack, that sits on top of the battery, and an overly resistive cable between the fuse pack and the alternator. The solution was: the cable end linked to the fuse pack was re-terminated, and the melted fuse pack was replaced. Between the tow and the repair, it set me back about $300. 00. . Read more...

The alternator cable got so hot it started a small fire in the fuse box on top of my battery. Completely melted/burnt the fuse box. I see there is a good pattern of this happening with these Jetta and beetles.
Alternator wiring harness overheated my battery fuse box and melted it. The vehicle battery light came on so I pulled over, turned the vehicle off, and inspected the battery, noticing the damage (melted plastic, smoke).
All warning indicators (abs, cel, airbag, ecp, battery and other instrument dash panel lights) would flicker repetitively until the car lost all power. After inspection of the engine compartment it was found that the alternator cable that attaches to the fuse box located on top of the battery was melting the fuse box and causing power distribution problems. The Volkswagen dealer recommended that they both be replaced as the cable could have become high resistance thereby causing excessive heat at the fuse box. I had the alternator cable replaced with an oem part and the fuse box with an aftermarket part. On 10-9-13 with 104k miles while driving to work at 6am in the morning, the exact same symptoms were experienced again. Luckily I was on a side road and was towed to a dealer which said that all oem parts should be used and that this is common as they had just replaced the alternator cable on another Jetta of the same generation. I requested the dealer check the entire electrical system including the alternator because the parts that were installed last year should not go bad in 1 year, the dealer said there was no other issue. I am not the only one experiencing a melting fuse box. At the links below are others who have experienced the same thing, even across other vw models. There seems to be a serious problem of melting of fuse boxes which can occur at any time the vehicle is in operation. . Read more...

(prior incident) 05/27/08 at 32k miles alternator harness burned and melted fuse panel (while car operating at low speed returning home from local trip). Fuse failed to prevent overheating of terminal connector on alternator harness at fuse panel. Current incident: 08/06/10 at 47k miles the alternator harness that had been replaced at 32k miles burned and melted fuse panel again, and alternator was also damaged requiring replacement (car failed to start at home after being parked overnight). Fuse again failed to prevent overheating of terminal connector on alternator harness at fuse panel.
As we were driving home, all the lights on the dash started blinking. The accelerator pedal stopped working in the middle of a busy intersection. The car engine continued running, but it just stalled in the middle of traffic and could not accelerate to get out of traffic. So we coasted the car for about 1. 5 miles to a family members house. When we arrived, we turned off the car and tried to restart it, it would not start. After opening the hood we noticed that the fuse box/harness that sits on the battery was very hot. We opened it and saw the far left black wire/cable was burnt up and melting the plastic in the harness. The black wire was extremely hot. I had this problem before, it was 3 years ago, but I did not know where to look. I spent over $500 fixing what seems to me the same problem as before. On the dealership receipt it said "found generator harness at battery fuse box melted causing high resistance in voltage circuit. . . . . Replaced fuse box and generator cable". On that occurrence it was so bad the burns had ruined my battery causing it to leak. I called vw manufacturing, but they were not very helpful and just told me to call my local dealer for assistance. They said it was not a safety issue, even if there was a fire hazard. My car is currently being looked, looking for an underlying cause for this. . . If it is the cable or something else in the engine. The connection was reset but the wire/cable continued to get excessively hot.
The contact owns a 2005 Volkswagen Jetta. The contact stated that the wiring that extended from the alternator to the power distribution center burned, causing the battery's inability to hold a charge and the engine's inability to start successfully. The vehicle was taken to a repair shop where the wires were replaced. Also, the gauges on the instrument cluster failed; while driving, the contact noticed that the gauges were moving around and not stay steady. The mechanic also replaced the instrument cluster and reprogrammed the computer. The contact called the manufacturer who offered no assistance. The failure mileage was approximately 67,000.

2003 Volkswagen Jetta gl was found to have fried cable from alternator leading to fuse box on top of battery. Problem was found and fixed 3 years prior to being found again at the dealership. Both times cable and fuse box were replaced. Pictures of the second incident are available. Also found that this incident has happened on other Jettas as well. Worried that could potentially cause a fire.
Vehicle shut down while driving twice, could result in car being disabled while driving at any speed any where becoming a very dangerous situation for the driver and an obstacle on the road for other drivers to try to avoid. Volkswagen dealership isolated this to a faulty harness connecting the alternator tothe fuse located on top of the battery. The harness and the fuse box had to be replaced. The dealership said this problem is only common to vw beatles and vw Jetta, because they said the car was 2002 it was out of warranty not covered. I was more concerned of the safety of life and property this problem would cause. I filed a complaint with the attorney general john krogers office in oregon, they sent me a letter stating they had forwarded this complaint to the national highway traffic safety admin in washington DC . I tried to contact them by phone, they asked if I had a confirmation # . I haven't as of yet received a letter or phone call.
1. 2002 vw Jetta wagon electrical system failure on expressway caused vehicle to stop & unable to start 9/6/09. Vehicle towed to dealer. 2. Vw dealer failure description, wire harness corrosion caused restriction in power flow in line which caused alternator to overwork and overheat wire harness and fuse panel. This extensive enough to cause melting of both wire harness and fuse panel over top of battery. 3. Vw dealer repair and replace wire harness and fuse body. 4. Vw customer care took information on my complaint about defect and potential safety issue but would do nothing referring me back to the dealer. My question was why did vw have such a defect where there was no fusible link that would fail first preventing the extensive damage that occurred.
Lost power, radio stopped working, a/c starting blowing hot air, epc light came on, battery light came on, abs light came on. Then the car would not crank. I thought the battery was dead so I jumped the car. I made it home then the car would not start the next morning. After examination I found that the fuse box on top of the battery had melted. The wire from the fuse box to the alternator overheated. Was told by two different Volkswagen dealerships in birmingham, al that this was a very common problem. If it is a common problem why is there no recall?.
Alternator wiring harness melted.
I purchased a used certified 2000 Volkswagen Jetta in January 2004, after only one week of purchasing the vehicle, the engine light came on, the accelerator was making a vibrating sound and stalling continuously. Okay, the transmission went out and it had to be replaced at my expense - I purchased a used transmission and then the engine throttle failed and the car wouldn't even start one day - had that replaced at my expense $1700. No the old parts are not available. Okay, there's more, the brakes have been replaced a total of four times within three years, the engine light is still on, air bag light on, brake light on, lights and fog interior fuses and exterior lights have been replaced I don't know how many times, I have put so much money into this vehicle - and it still is running badly. As of today, the car won't move without warming it up first for about 45 minutes fully - when you press on the accelerator without warming it up first - it will stall and make a loud embarrassing noise as if the engine is going to explode - and you have to literally make it move by pressing very hard on the accelerator and praying that it won't just shut off while driving and never start again. My vehicle has 117,000 miles on it had 43,500 when I bought it (I know stupid wasn't I) it was my first vehicle. I know a car is not suppose to last forever, but dam does it have to cost so much to try and keep it running until it dies. Please help me with any information you may have to assist me in this matter.

Like others, I have had the ignition coil replaced. This happened after the warranty expired, of course. I have also had electrical problems with the windows (regulator and motor) for all of them. Now, my check engine light is flashing and the car is sputtering. I know the secondary air intake valve needs replacing but it did not cause problems. Now I'm wondering if something new is wrong??? also, I was having problems with losing coolant and had to continuously replace antifreeze. After fixing what I thought was a small leak the entire system will not produce cool air! this car has been nothing but problems and vw should look into all of these complaints.

I purchased a 01 Volkswagen Jetta in July of 04 and in les than a month it began to stall as I was driving, so I pulled over and it could not start again. I got it towed was told it was my battery and got that replaced, then it happened again a few months later and I was told it was my alternator and got that changed. A few month ago the car would not start again, I was told it was my sensors and got that changed, within 2 months it has happened about 6 times and I've had 3 diagnostic tests that reveal nothing is wrong with the car. I don't know what else to do, al least if I know what the problem is I can fix it. But my car keeps refusing to start( for hours at a time) and everyone tells me the car is ok.

My 1997 Jetta was purchased new in August 1997 in canada. In 1997, the electric moon roof and the electric window had intermittent fault of not operating and were fixed. However after the warranty period one rear electric window could not be operated locally. In oct 28, 2004 the generator was faulty and was replaced by a re-built unit at owner's cost. In oct 30, the ignition switch was replaced at the extended warranty. From oct 30 to 31, 2004, an intermitent fault occurred 5 times on the panel cluster, all readings in the cluster (tachometer, speedometer, temperaure and fuel gauges) drop to zero for a short period of time and resumed normal. The dealer has not yet located the cause of the intermitent fault. If the panel c;uster were found faluty, it would be a very cost repair. The electrical system on my 1997 Jetta are exceeding unreliable with a high intermittent fault. It is the responsiblity of the vwoa to pay the repair cost for such faulty electrical system.
Problems with vehicle's brake lights. On three occasions, the window regulator clips were replaced. Currently the brake light switch needed to be replaced for a third time.
This is a known problem with vw/Audi 1. 8t engines. Affects Audi a4, vw passat/beetle/jetta. Parts back ordered through dealer, they said. Needs to be a recall.
