Golf IV / Jetta IV :: Lights Keep Flickering Slightly
Jan 30, 2015
I have an 03 Golf VR6 and only has 76k on it. Ive only had it a week but I have come to notice a couple peculiarities. So first off at night regardless of speed or RPMs, ALL OF MY LIGHTS have a slight flicker. Its not a huge difference, but its definitely noticeable. Engine runs fine. No battery light. Additionally, twice when I go to start it in the morning, after starting the alternator workshop light will kick on. after giving it a tiny bit of gas it goes away and doesn't come back. Everything else seems fine. no check engine lights, no trip meter resetting, and the flickering seems to be sporadically. Tonight I tested the battery and alternator and both tested good. My only thought is that it might be a loose ground. Tomorrow I plan on taking a look at the ground under the battery. I've tried searching the threads here, but Im having trouble finding any relevant info. Also, is the voltage regulator inside the alternator, a separate piece, or in the ecm?

Noticed a slight flickering of my guage lights recently. All other lights in the car as well as all screened displays are stable and do not fluctuate. I've raised and lowered the instrument dimmer control which functions as it should to no avail. Voltage of left battery is to spec so I assume the alternators output is OK.

I have an automatic (ugh) 2002 Jetta 1.8T that is displaying some fun stuff. My kneejerk reaction is that the ECU is croaking but wanted to run it by some people with more experience/smarts.
Here's the deal. I don't get any codes, ever. Sometimes, when I turn the ignition to on (Before starting) all of my warning lights are dim and will flicker, and the gear indicator at the bottom of the cluster rapidly switches between each gear. If I start the car like this, I can hear the shift lock randomly engaging and disengaging. If I actually try to drive, it'll shift hard into reverse, shift normally into drive, and then drive in limp mode. I only drove this way three times before figuring out the next bit. Each time, either the traction control or air bag warning lights came on and stayed on.
I've noticed that if I turn the ignition to "on" and it's acting up, all I have to do is leave it on for a few seconds, turn the ignition back off, and turn it back on; sometimes it'll take 2-3 tries but it always seems to work. Then the warning lights come on bright and steady, the car starts like normal, and drives great.
So, is it the ECU? Is it demons?

I know this is a common problem, it sounded like the coolant resevoir was the place to start so I replaced it today and I still have the low coolant light blinking, I don't know what else to do.

Last night, I was driving around and noticed that my lights seemed to be flickering and dimming like CRAZY. It was really bad. Not just the headlights, but all the lights. The climatronic, radio, dash, map etc. The climatronic seemed to make things worse, but it did it even without it on.
Then I was in my buddys driveway in neutral and noticed that if i gave it some gas, the lights got brighter...it wasn't a small difference either...like when the lights dimmed, it was nearly HALF as bright! its like the car was losing juice big time...
I checked my battery cables this morning and they're tight. the car starts right up in the cold so I don't think its my battery. what other signs of alternator failure would i be noticing, or could it be something else?

Just put a side post battery with top post adapters on. I drive to town the battery light was flickering with every little bump finally it turned off. Got to the house car shut off tried to turn it on and nothing no click nothing. The dash lit up half way the radio flickered on and off constantly and and the ebrake light flashed with a beep. I'm at wits end. Just bought a tire and battery and filled the tank and now this happens. 2000 jetta 2.0 GL.....

I've been experiencing power loss at random times while driving, idling, With almost always flickering headlights on my mkiv 1.8t gti. Also on what always seems like the exact same spot on the freeway I'm losing all power to the wheels and it feels as if my plugs aren't firing for about 10 seconds Which causes me to bog down. At which point I down shift and play the throttle until my motor then begins running normally again.
I've semi recently replaced my battery and terminals, due to corroded terminals and worn out battery. Is is possible a ecu reset could solve this problem?
Also when the power surges during driving my traction control and hand-brake lights on the tachometer will flash and the car will beep three or four times (same as when the hand-brake on beep).

I went to get in car today, and the driver screen, needles, and dash lighting was flicking or pulsing.. like a wave rolling through the lcd. its got 1k miles on it, jsw tdi.
i did open the trunk, without unlocking from fob, just trunk button, then it auto locked again when i shut it. have never done that before, so maybe this causes it? i let it sit awhile, and all back to normal.
on a side note, got my 20% tint on all around today and looking good need a drop then wheels.

So I just noticed now that my car is popping slightly at idle occasionally...It doesn't do it all the time and the idle is kinda lumpy but always holds at 800-900. Sometimes it drops a bit lower.
Also when starting it up in the morning, or when the engine is cold it doesnt rev up to 1500rpms it just starts and immediately drops to 800-900??
When I press on the gas and keep the pedal at one spot, say 2000rpms, it slowly drops down to 1500??

So to start off, its 10 degrees here with a -7 degree windchill. With that in mind, I was driving home just now from dropping off a friend, and noticed my engine temp was slightly about 190. Didn't think much of it, but within a mile down the road the temp was crossing the final line before the red 260 degree line. I pulled over and let it get down to 190 (luckily didn't take long) but in the next 3 miles home it rose again, then fell, and then rose again as I drove through my neighborhood. I'm thinking maybe the thermostat is going bad...? There's no way it went from normal operating temp to almost overheating as cold as it is....

The brake light came on randomly yesterday, flashing foe about 5 seconds, then shut off. Hasn't come on since, but I looked at the brake fluid resovior and the level is about .5cm (.2inches) below the "min" marker.
Can I just open the resovior, pour in the fluid, recap it and go? I remember hearing from someone that if you open the resovior cap at any time, air rushes in and you must bleed the entire system before you can drive again

I'm trying to adjust the headlights on my Jetta wagon. I know the basic way to go about doing that theoretically, but how to actually adjust the headlights? Are there screws or something somewhere? I also thought I read somewhere that the car automatically adjusts the headlights slightly as your driving? How do I account for that?

I recently purchased my first car/jetta. When i switch the knob to turn on the instrument lights on my 2000 jetta the headlights don't come on. But when i turn the knob off the auto headlights turn on. Any insight on this? when i first got the car everything was working fine. It only started to happen after I replaced the radiator.

I just noticed that the headlights are flickering like crazy, both of them. I was trying to hold them from the inside but they are still doing it. I dont think they are moving.

My wagon 2003 l-300 has flickering lights and when the radio is off you can hear the engine whine. Is this a grounding problem or is the alternating system going out? I have checked all the connections and do not see anything obvious. What to check.

I started the car this morning, plugged the phone charger into the lighter socket, noticed the charger light wasn't on, pressed the charger in tighter, the car started to run funny, then it cut off. Lights work, radio won't work, all fuses are alright upon several visual inspections. Car wants to turn over but won't start. I tried disconnecting the negative battery cable to see if the car would revert back to "normal". I have never had a problem with this car in the two years I've had it; the battery was purchased brand new in November of 2011. I unplugged the cigarette lighter to see if that would work but nothing so far. Could it be the ignition switch?!

I have the Bi-xenon's I had installed on the top and I wanted my Fog lights to match. At a performance shop they installed Can Bus Ballasts with 6000K light to match the top Xenon's. I turned Cornering lights off in VI -COM so my car will stop kicking on the dash light every time I turn a corner. Here the weird part.
If I turn my fog lights on during the day NO FLICKERING. But at night the front left Flickers. I've replaced the Ballast and the light and it still does it. I think it has something to do with the Automatic Switch that turns the lights on at night.

So I swapped out my OEM battery for one straight from Hyundai and during the first night time drive, I immediately noticed a very severe flicker with the lights (headlights, interior and trunk) when idling that was definitely not there with the original battery. I have already done the ground strap mod so I went back and re-cleaned the grounding points and even filed down the grounding post on the new battery itself but the problem remains.
I'm thinking I either got the wrong battery or a bum one and the alternator is only a year or so old.

The last month or so, I have noticed that my dash board lights (red lights) and my actual interior lights that come on when you open the doors to vehicle will flicker sometimes...And it can get bad I guess and annoying. It's more of it pulsating really. I noticed today while driving home and I had the radio on loud it was doing it and I do not know if was just in my head that it was doing it more when the radio was loud or what, but this is ridiculous.

Just recently bought the car a month ago. This car has been giving me a lot of headaches. First my radio unit wouldn't work properly. Just started my car today and my gauges are flickering. Seatbelt and airbag keep flickering on and off. AC says 32.0 temp and wont let me adjust it. Passenger windows don't work. Driver window goes up and down but isn't automatic anymore. I have to hold it both ways.
