Golf IV / Jetta IV :: 1.8t - Headlights Dim With The Idle Drop / Battery Light Is On
May 8, 2014
So recently my water pump failed so i did the pump, timing belt, and thermostat. While putting the alternator back in a may have broken a few fins on the alt. case. Anyways I was ripping it a bit today only a day after stuff done and the battery light came on. The car is warmed up and the idle drop a few hundred rpm and then back up. The headlights dim as well. and come back up with rpm. Even when I hod the pedal steady at 2k rpm itll still dip and come back up...thinking its an alt but is that really a symptom of a bad alt? I was also thinking I didn't tighten the alt bolt down alt the way or fuses or something so checking that but I am almost positive it's all tight down.

The other day i started my car after school and about two minutes after the car started the battery light came on. A little bit later, the gauges went to zero but the car was still running, On my way home from school, it did it again twice then the battery light came on and stayed on. I got home and tried bringing the car to autozone and all the lights on the dash went dim and the car slowly died.

I've got a problem with the girlfriends golf. Last month she tried to start it and the battery was flat. Didn't think much to it as it was a very old battery and the car had been sitting idle for a few weeks. Swapped the battery for a new one and it started fine. She's been driving it since then until Yesterday when the battery went flat again. The car will start if bumped and when it does the battery light goes out on the dash and the headlights etc. work at full brightness but it doesn't seem to charge the battery. I checked the Battery voltage when it wouldn't start and it was just under 12. With the engine running it only goes up to about 12.6 which I know is too low. I've read a few posts about one of the wires from the back of the alternator causing it not to charge but I can't understand why the battery light would go out when it starts?

I have a 2.0 Avh jetta. Around January I started getting intermittent cel coming up. I pulled the code back then and it said it was misfiring cylinders. It'd give me some rough idling when it was on. Since then the light would come on during wet weather. About a week ago the light came on and stayed on. I haven't been able to pull a code recently though to see if it is the same as before (cant get vcds to connect to my car for some reason).
My car has randomly died with a battery light (electronics stay on, engine shuts off) and I know this is pretty dangerous but it hasn't happened on a main road. I replaced the coilpack yesterday and planned to change the spark plugs as well but the spark plugs turned out to be more than i was equipped for (i do have them). Since I replaced the coilpack the car no longer rough idles but it did shut off with the battery light coming on. I'm really trying to avoid taking it in somewhere but I'm starting to think that is my only option left.
Should also add that the car starts up just fine initially but after a random battery light shut off it is a hard start and sometimes takes a few tries...

A week ago before I left for h20 my battery light came on, i drove for 10 mins and it went off. I also had a battery test and alternator test at that time and everything showed up ok. I drove 800 miles all good. Last night the battery light came on again, I was far from home so just tried making it back but the car dies on me. Before it died the traction and abs light turned on, the lights dimmed, when I gassed it the lights would get a tiny bit brighter. Also my gauges got stuck at the rpm i was driving at and 70 mph, even though i came to a stop already.
When i tried to gas the car it was backfiring, sometimes i couldn't even give it gas. Only way to start the car was to jump it, then i can drive a little before the car died again.
I drove with my battery box off the highway because highway patrol said i have to and got towed how from there last night. The ALTERNATOR AND BATTERY WERE CHANGED a year and a half ago apx 12000 miles, all oem equipment for the alternator. The serpentine belt and tensioner on top have also been changed and serviced.

I bought a golf mk4 2000 and sometimes when rains the battery light comes up and the power (electricity) of the golf goes a bit out, but it don't turn off. It is only when is lots of water on the road.
Symtoms:
The handle gets hard
A/C stops for a second
Light flickers
I can solve it buying a splash engine cover? Or I should check something else.

Really weird thing is going on with my 03 1.8t Jetta, sometimes when I am driving the battery light will come on. It will turn off when I slow down but will turn back on as soon as I accelerate. After a while of this happening I will hear a burst of air and the car will jerk back a little bit then drive perfectly normal. I've looked all over google and posted in a local Euro car group`and haven't found anything.

I have an 02 GTI w/ 1.8t and 5spd. I was in the drive through and all of the sudden the ABS, ASR, and seatbelt lights came on and the battery light is randomly blinking. I got home turned the car off and went to restart it and when I turn the key nothing happens. I should also mention I recently have 2 cels for p0701 lean condition and bank 1&3 misfires that developed after I replaced a bad injector. Where do I even start?

have a 2000 golf TDI 5 SPD Manuel. Was driving into work today and I got on the gas a bit and all the sudden the battery light comes on I hear the beep dash noise and my guage cluster shuts off. I pull into work. Car seems to be running fine.. All belts intact. battery brand new. Car starts and operates fine. At idle dash works. But when I tap the accelerator pedal that's when dash shuts off and battery light comes on. Bizarre. I checked a few fuses not exactly sure which one would be bad but. I didn't see any popped ones. I did notice that my top cluster of fuses all the connecting points are browning but fuses are good. So I am not sure if it was already like that....

Was driving just a few hundred feet up the road to local mini mart. On the way home after pulling out of the shop, my battery light flickered once and twice before staying on. I circled around the block to see if it would go away, but it was still on when I parked in my driveway. I noticed a ticking noise in the engine bay, but decided to turn it off.
About 10 minutes later, I turned the car back on. Battery light still on, noise still evident in the bay. I popped the hood and it's coming by the serpentine belt. That seemed to be running fine over there and couldn't see anything that looked out of the ordinary. I went in the car to rev up the engine a bit and turn on my lights, and that's when the symptoms got weirder. My RPMs jumped to about 1,000 and stayed there (even when I let on the gas a bit); my blowers would work (but not the screen showing the temp); CD player turned off; and I got a cluster full of lights on my dash. The car would idol rough when turning lights on and off.
It eventually shut off, and now there is no crank or nothing. All lights still work, alarm works, but no turn over or clicking. I'm going to try and get it jumped when able to, but I'm not sure what the problem could be. I can't find the exact paperwork, but I had the alternator replaced at around 85,000 miles.

Recently bought a MK4 for 1500, I already knew the car would have problems at some point. To make a long story short. I was driving yesterday, I was in 5th gear, going around 55 mph. Out of no where my battery light comes on and next thing I know the power steering goes. The car completely shut off out of no where, there was no noise or anything that would warn me except the battery light. So I automatically thought the alternator must have went. I checked the alternator and battery. The battery was from September of 2011 so.I bought a new one and thought that maybe that was the problem. The car didn't do anything, it didn't even crank it would do absolutely nothing. The funny part is, which has me puzzled is that the lights, radio and other electronics work fine. I don't know if it's either the alternator, ignition coil, the starter, or the wire harness. What this could be?

After about a 45 minute drive yesterday the EPC light came on, idle went up to 1200 rpm's and when I turned off the car it wouldn't turn on, just leaving the ignition for about 5-7 seconds is when the car finally started.
Today, again after a 45 minute drive the EPC light came on again, same symptoms, except that the car stalled and I had to turn the ignition again about 5-7 seconds for it to start. No other light is on, and the car would start fine after about half an hour rest with no EPC light.

Recently I believe i got a tank of bad gas. Was having problems starting. Finished it off filled up used injector cleaner and dry gas to clean it out a bit more. Now as I was driving the car would basically stall out but kick back in as I was driving and the EPC light would come on. I've been reading up and most answers are a bad coil pack. I pulled them all out and checked them they all look pretty good. No codes are popping up for it a coil pack. Unless I need a specific VW model computer to check. I'm gonna check the volts on the coil packs today to see as well.
The EPC light does go off after the car sits a while. It comes back after a few miles driving. After the EPC light comes on my car will idle at 1200 RPMs up from 800 when its normal.

When idle, and especially when cold, my R engine tends to do some popping, I can see the RPM drop slightly when this happens and can also hear and feel it in the car and from the engine and exhaust. This only happens when idle, I have no other issues, no drop in performance and no CEL.
It actually has done this for a while now but barely noticeable. Now since 2 weeks it has gone worse to the level of being annoying. What this may be ? Injectors maybe ?

Just noticed today that I have a slight drop in boost. Normal boost is 1.5 bar but today it is running slightly lower boost and does not have the same pull through all the gears.

Car becomes harder to start before the problem starts occurring. When the car is started, the idle will rise above what it normally does (750rpm) to 1200-1300rpms and drop back down and raise back up again. Its like its constantly revving itself, this continues the whole time the gas is not being applied. With this comes the EPC light, the Traction Control light and a hardness to the brake pedal (as if the brake booster hose is disconnected or its not getting its vacuum assist, very hard to brake when rpms are at idle). Sometimes im able to boost but most of the time, i am not able to exceed 2lbs of boost. Limp Mode? This has happened before about 5k ago.
I sacked up and got it diagnosed and it turned out to be the Throttle Body, Crankshaft position sensor and the brake booster hose. All at the same time, which is weird. But all those items were replaced by me and the car ran fantastic. until now. This will be the 3rd throttle body put in since the car came off the line. it seems like thats the problem since the brake booster hose is fed vacuum to the throttle body? But i would love second or third opinion before money is spent. If it is the throttle body, what could make this unit go out so systematically and slowly? If it was wiring then you would thing itd kill the part quicker than 5-10k miles. I will post the CEL codes when i can get one to come on.

I have been noticing that the idle in my car while stopped at a light will sometimes drop to 500 rpm. This makes the car feel shaky at idle. As soon as I put it into neutral or reverse the rpm jump to 750 rpm. Intermittent issue, what this could be??? Its probably happened 3-4 times in the last 6 weeks. Its annoying.

I have had my golf R for 7 months now and ever sense I got tuned I have had this little issue. Besides this the car is amazing but ever now and then the car while coming to a stop and put it in natural to come to a stop the idle will go to 500 then come back up to 1200 then rest at 800. I'm getting my PCV replaced tomorrow. I'm um stage 2 tune fully loaded with Bsh intake full 3" exhaust.

I purchased a 2001 Jetta and it ran alright for a few days then all these problems started arising. The engine would not idle correctly and then a week later my EPC light started coming on. After all of that I have replaced the Throttle body ( Bosch) the MAF ( after market) and gas pedal ( after market). It ran fine for a day and then same issues. I had a mechanic relearn the throttle which had the Engine light go away for about a day. Now all the issues have came back. Here are the main problems.
1. Randomly lose throttle ( up hill, down hill, highway does not matter)
2. I randomly get stuck in park and cannot shift at all.
This is extremely troublesome since every time I lose throttle i have to put the car in park, shut her off and turn her back on to be able to drive. I keep getting the Throttle and MAF codes. I also checked on the recalled parts and they have already been replaced. I have read many reasons as to what would cause this but even the mechanic doesn't even know and I cant pay for him to check the electric. Also when driving if it is raining my car will not start or when it does it chugs. I was running through a puddle and after the water splashed the car basically would no longer run.
