Volkswagen Jetta TDI Problem Report
Volkswagen Jetta TDI One or Both Head Lights May Not Work
One or both head lights may not work due to premature head light bulb burnout and/or bulb harness failure. Care should be taken to inspect the head light harness connector for damage when replacing bulbs. Damaged connectors should be replaced.
Over the 16 months I have owned the vehicle (purchased new from VW dealer), the front headlamp bulbs have required replacement 4-5 times. On the second and third failures, the entire headlamp assembly was replaced by VW just before the 36K warranty expired. This did not fix the problem, as I continue experience bulb failures about every 10K miles. Unlike many post on forums, which discuss hot wires or loose connections, my issues have been solely bulbs that burn out. I have substitued various types of H7 to see if it is a bulb reliability problem, but the frequency of bulb failure has not changed. - Visitor
CANADA hAVE CHANGED 4 TIMES ALREADY - Lyzoo
I find I am replacing headlights once a month, ever since the car hit about 40K miles (now we are at 80K). We are becoming experts at changing the bulbs and are careful to never touch the bulb. We've tried multiple brands with no change in longevity. I drive mainly highways with few potholes. I do travel about 3200 miles a month and have the headlights on day and night, but this seems like a lot of headlight changes compared to other vehicles I've owned. My previous car was a Camry, it got almost the same number of miles per month on much rougher roads and weather, and I don't remember changing the headlights more than once or twice in 5 years. - Visitor
2012 VW jetta SE. the low beams bulbs burn out every week or two. Using Sylania bulbs, no moisture is in the headlamp assembly, no finger oils get on the bulbs during installation. I'm assuming it's a wiring problem. - Visitor
I've had premature bulb burnout continually with this car. I've started replacing both when one burns out because I would replace one headlight and within a week or two the other one would go. - Visitor
I had headlight bulb burnout several times, I had my mechanic put a sealant on the top of the headlight and it seem to fix the problem. - Visitor
Both headlights went out at the same time. The dealership blew me off and said it was just a rare situation. I'm also having intermittent issues with the trunk lights as well. Normally if I tap on the lense lightly they come back on. - 2013TDIowner
2 months ago i replace a blown headlight with sylvania hid. Both my headlights are now blown again. I tried to replace with new bulbs and it won't work. Have to take it to a dealership to find out the issue. My horn also doesn't work. Wonder what it will cost to get this repaired. Hopefully this is not an reoccurring issue. - Paulhents
I've had my Jetta since July 2012. Bought it brand new from the dealership. Before the first oil change @ approximately 9800 miles I had a blown headlight. I brought it to the attention of the service tech and asked her if it should last longer than it did and her reply was these things sometimes happen. Well, I've replaced both now and it's happened again at 41000 miles. - leadfoot126
Replace the headlight about three times on each side. - Visitor
Appr every 16000 miles one of the headlight bulbs have had to be replaced. The dealership has found no fault in the harness...only the bulbs, and changing the blown one or both does not affect the longevity of the bulbs...one will blow appr every 16000 miles. - Visitor
