Golf IV / Jetta IV :: 2002 - EPC And Traction Control Light Came On / Rough Idle
Jan 30, 2015
2002 GTI 1.8t (No Tune) 95k
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 a 202 Jetta 1.8T GLS. Sometimes the traction control light comes on and the car jumps like it cant figure out what gear to go in. It gets very interesting to drive when it does this as I am sure you can imagine. Only other light that is on is the engine control light which is on all the time. Car seems to run fine until this happens. If I pull over and shut the car off it seems fine when I start it up again and continues to run fine and all of a sudden it happens again. I do have a code p2637 Torque Management feedback signal "A".

I know this has been covered. but when i searched it was all mechanical failure.
My abs/traction lights come on together whenever it snows, and i lose both abs and traction control. But in the warm weather it is fine. it ocassionally happens when it rains (but a lot less often)

I was pulling out of school the other day and my abs light came on and so did the traction control light, noting was going on at all. I was driving in a straight line. Everything works perfect i have no issues just lights, about 2 months ago. I did coilovers rotors and pad all the way around and a new abs sensor on the drivers side because i smashed it when installing the coilovers. I need to get it fixed because I cant pass inspection with the lights on and I am curious to find out if something is actually wrong with it. My uncle drove it and said it makes a noise when you turn and he thinks possibly the cv joint is bad on the axles? He said because of the excess strain from the drop.

My car's front bumper got ripped off this week , parking spots on the grass pulled it off) Ever since then, I've been having weird ass issues. After it happened, I zip tied it back together and started to go to town when my car kicked itself into EPC mode, but only when I went on the throttle. If I let off, the EPC light would go off, but the traction control light would stay on (ESP light, whatever). I killed it and realigned the throttle body (I think that's what it is. Where you hold the brake and throttle in for about 30-60 seconds while the key is on but not started then kill it and restart it) and after I did that, it will start and only stay alive for half a second then die. It's started to make a god-awful crackling noise as well in the engine compartment near the Alternator.

Just replaced one outer tie rod end on my 2003 GLI yesterday. (ran out of daylight to do other side, now have another problem)...
Everything came apart and went back together fine with really no fighting. Got the alignment close, but will still need one done once I finish up.
Anyways, I am wondering what I possibly could have screwed up, because after a few miles of driving the traction control light (circle with triangle in the middle) came on and now won't go away. I didn't screw with any wires while I was in there. Pretty straight forward job, so I thought. I don't have a VAGCOM but there's no engine codes stored.

I have a 2004 Jetta GLS with 125K miles and standard transmission. Just had the clutch completely replaced. After I picked the car up, I ran some errands, turning the car off and on a few times. Then the ABS/traction control light came on. I tested the brakes, which seem fine, and accelerated on some ice, with no flashing light like usual, so that's a concern. Came home and used the VAG software - no fault codes came up. Went back to mechanic, who said the clutch and this new issue are not related, but he checked my wiring, checked for fault codes, and took it for a test drive. Said he did make the flashing light come on. Turned the warning light off. It came back the next day.
My questions:
- Could this be related to the clutch being replaced?
- Is this something I should worry about, or just live with the light on?

02 Jetta GLS ... 1.8 Liter Turbo ... 5 speed manual
Threw a lot of codes I don't know the #s but I can get them tomorrow, but I know there was a throttle pedal sensor, cam sensor, MAF, turbo, and a computer one.
I've had the car 2 weeks and its driven fine every day until today I backed out of my drive way after doing some driving earlier in the day and popped it into first and she fell on her face, no power rpm's were near 300. shut it off start it back up idles a little rough and I have a traction control light CEL and EPC lights all on. when I first take off it chugs and is hard to even get going and then it takes miles to get up to speed. I can put the pedal to the metal and my rpms barely budge and the car ever so slowly gains speed, she eventually will top out around 70. but that's after quite a stretch.
This happened one other time and after a few minutes everything went back to normal for nearly a week , this time no such luck.
Possibilities to shoot down maybe?
-fuel filter/system
-Cat. converter
-MAF sensor
-Coil packs
-computer something??
-throttle body
-turbo
-electrical

Just bought a 2004 with 240000 on it. Yesterday it started accelerating roughly. Today did the same and the traction control light came on and off several times. And just half hour ago I drove it about 10 minutes in town and the check engine light came on and stayed on.

I put in a new air filter today, 2003 GTI vr6 24v, and three lights (Check Engine Light, Electronic Control Power, and ABS) all turned on and haven't turned off yet, I'm not sure if I plugged in the sensor wrong or if there is something else that needs to be done. None of the lights were on before.

I was driving my car and forgot to turn esp off, hit boost in 2nd gear and the traction control did it's thing. didn't notice anything while driving so I didn't think anything of it. once I got home to back into my driveway, I noticed that when I turn the wheel sharply (at a standstill or very low speed) there's a clunking coming from what seems like the passenger front. I'm hoping it's not the inner cv. What it could be? I know for a fact it started right after the traction control kicked on so that's what caused it.

My car sat for 2 days this week and was completely dead when I got back. I had the alternator and battery tested and they were both fine. I put everything back and ran a vag-com and it still shows running voltage at 9.7 volts. ABS and traction control lights are on intermittently. It seems to be having trouble starting which leads me to believe it's a bad starter but I don't know how that would drain my battery. The car also has a sunroof drain leak which got water on the monsoon amp. I've tried with and without the amp connected. No difference.

Son was driving his car today and the roads were patchy ice leaving the addition. As he went around a turn the car started to slip and traction control kicked in. Right after that the trac off light came on and won't go off. Tried recycling the trac switch on and off to no avail. Tried to check the fuse but can't find where it is located.

So recently (yesterday and today) when driving I've noticed that my ABS and traction control lights come on along with the usual CEL for a bad 02 sensor, what could be causing these to come on, the part that throws me off is that it only happens when it is wet outside or if I run through a puddle...

My traction control light came on today, and it's just...on. I am not sure what that could be. I checked to make sure the maf was on snug, Other than that I'm at a loss. Scanned it and found no codes relating. Just the dumb convenience center module.

I have 2002 Ford Taurus SES. Currently the brake light is on and the ABS and traction control are not working. The brakes have been checked and are ok and it has been hooked up to a code reader and no codes come up. Occasionally the light will go off and the abs and traction control work for awhile.
