Golf IV / Jetta IV :: Running Rough / Flat Spot When Accelerating Around 2000 And 2600 RPM
My 2.0 recently had some problems with the coil pack so I replaced it. Now my car hits a "flat spot" when accelerating around 2000 RPM and then another around 2600 RPM. If I am in 3rd gear going about 20MPH and I press the gas about 25-30% it sort of shakes and won't accelerate and when I take my foot off the gas and slowly ease the pedal down it accelerates fine.
My car also runs pretty rough at a cold idle(misfires). When I press the gas it sounds smooth until it gets back to idle. At any temp my car runs really rough with the A/C on. I also hear a rattle/Buzz around my relay panel when the A/C is on. My car is a 1999 2.0 AEG. I don't have VAG-COM just a generic scanner and the last codes I got were:
P0134
P0135
P0141
I replaced both O2 sensors and the beginning of this year and those codes came back right after I did them. I will scan tomorrow and post any new codes.

View 9 RepliesAccent LC (2000-05) :: Hard Starting / Will Not Stay Running When Engine Is Cold
My daughter has a 2000 accent , SOHC 12V, I think it's the 1.5L.. It will not stay running when the engine is cold...........after it warms up, or if it sits in the hot sun it's fine................it has 166K .
She said she took it to an auto parts store and had the engine code read, p1123 came up.....
Code P1123 : Long term fuel trim, at idle - mixture too rich..
What do you think this is caused by................ the inlet air temp sensor? I was told someone just replaced the air max flow sensor, that don't sound correct to me, but that's what they called it....probably the MAF sensor....
Golf IV / Jetta IV :: Right Blinker Started To Randomly Come On And Stay On

View 2 RepliesGolf IV / Jetta IV :: Coolant Gauge Jumps From 0 To 190 Comes Down To 0 And Stay Sometimes?
The coolant gauge jumps from 0 to 190, comes down to 0, stays at 1/4 the way down... jumps to 190, sometimes stays at 190, sometimes stays at 0. All this while driving. I was thinking it could be the temperature sensor since it's not a green top? I also read there are other parts like the sender that could be the problem. I have been trying to find similar problems and was unlucky.
View 2 RepliesGolf IV / Jetta IV :: 2005 - Lights Stay On After Locking
My girlfriend's 2005 Jetta has started intermittently leaving its lights on after she locks the car. It seems to happen with the fob OR with the keys in the lock. It started a few weeks ago with just the left rear turn signal. Now it is starting to do all four corners and the repeater on the front fenders.
The lights don't blink, they stay on solid usually after doing the normal "lock blink" and noise. This obviously drains the battery so we've had to jump it a few times.
How to fix this? To me it is obviously something electronic, but I didn't know if I should look to replace relays/fuses/wires/etc.
Golf IV / Jetta IV :: Clutch Not Stay Engaged After New AC Compressor Installed
99 Jetta, installed a new AC compressor a month ago, has been working great, not clutch will engage for a few moments, then turn off for a minute, then engage again. Seems, like there is Freon in there by the gauge on the low side.

My AC is not working. I just tried to put in some freon and it did nothing for me. Hopefully this doesn't make matters worse, I'm finding that it may have..
From what I can tell everything is working fine except the pipes at the firewall that go to the evaporator stay warm and don't cool at all after ten minutes.
The clutch is engaging when the AC button is pressed and stays on fine.
I found this thread : [URL] .....
about the blend door, that could be it haven't checked yet but does it suggest that the condenser isn't working since the pipes don't get cold?
Golf IV / Jetta IV :: 2001 1.8T Does Not Stay On / Stalls Out On Cold Start
When the weather gets cold, (lower than 45 deg. F) my Jetta does not want to stay running. It turns over and starts just fine but it does not like to stay on. When I turn the key to the #2 position I can hear the fuel pump fire up and pressurize the system. I always attempt to start it after that, and after 1-2 seconds of running, it seems like it chokes itself out. I have the new coolant temp. sensor (green top), my MAF has been replaced, all spark plugs are new with the correct gap (approx. .030"), new air filter, I run 93 octane fuel.
The worst part is, once the car is warmed up (After forcing it fuel and starting it over, and over, and over again) it runs awesome! I have had this problem since I bought the car (about 2 years ago). The owner told me about it and mentioned that he has never been able to figure it out either (trips to the dealer included). I have been dealing with it for 2 years, but it is getting much worse. Over the past 2 days I have not been able to get my car to stay on long enough to get it to move.
Golf IV / Jetta IV :: 2001 - When The Car Is Turned Off The Cooling Fans Stay On
I have a 2001 jetta 1.8 turbo. when I turn the car off the cooling fans stay on and kill my battery. Ive been told it could either be a relay or temp sending unit but i dont know what one to tackle first, also my coolent temp stays way low almost as if the thermostat is stuck open.

I have a 03 GLI 24V VR6 6 speed and im having an issue with the brake light.. ive checked all the fuses and emergency brake sensor and they are all good, the issue is the brake light flashes 3 times then will stay on almost immediately and whenever it does the entire drive of the car changes.. without the light on the car runs fine but when it comes on its like the car goes to a limp mode and is leaning out on fuel.. it wont rev past 4k it falls on its face and basically jerks along until I get where I am going.. I've replaced ABS speed sensors, MAF, and front brakes and axles recently.. before this was an random issue that would come and go but now its almost every time and it makes it undriveable..
View 1 RepliesGolf IV / Jetta IV :: Car Overheats After Running For About 10 Minutes
After running at normal temperature for about 10 minutes, my car starts to overheat. I noticed my radiator fan wasn't running at any speed, but my auxiliary fan was running fine. I checked the thermal switch and that was okay, because the auxiliary A/C fan still worked after jumping, and the big fan didn't. I replaced the fan assembly and now both fans work fine, so I assume that my thermostat is okay (maybe not and I'm missing something?). Even though both fans are running, my car still overheats, but maybe after 15 minutes now as opposed to 10. Water pump seems to be fine because I can see it pumping back into the coolant reservoir, and it doesn't seem to be sputtering or anything. Just replaced coolant recently after flushing with water, so I assume that the radiator isn't clogged. I also recently replaced the oil because it needed it anyway. It is still overheating so now I'm stuck. I can get to work and back because it's only a 5 minute trip and it doesn't have time to overheat, but I don't want to keep driving it obviously.
View 9 RepliesGolf IV / Jetta IV :: CEL Came On After Running Idle For About 45 Seconds
I was coming at the climb, my car hit limp mode twice and later I noticed my CEL was on. I let it sit over night when I got where I was going and started it up today started fine but the CEL came on after it ran idle for about 45 seconds. I check the oil and it was on the low end. What it could be?
I drive a mk4 tdi with a malone tune. I am heading back to the valley tomorrow evening I'm just by kamloops right now. Also what oil should I top it with just so it isn't so low for the return trip? (Always get my oil done at the shop)
Golf IV / Jetta IV :: 2003 GLI 24v VR6 Running Rough And Stalling Out
I have been beatingy head against the wall for the last month with this car. It started out by just running really rough and stalling out. Found out that I had a bad clamp on the air intake that attaches to the throttle body. Replace that after I already replaced the MAF. Everything was great till couple days later then the car just crank crank crank no fire....
I cleaned the grounds pulled the plugs and coils, had perfect spark. Put everything back come to find out after going thru my Bentley manuals I jumped around the fuel pump relay fuel pump kicked on perfect started great! Replaced the fuel pump relay BAM! Ran great!!!! For 2 days..... After that right when I pulled into the drive way the car would not start.... So I tried everything again.... To no avail..... Check the codes again, now I'm throwing these codes which yes I did cross reference in my Bentley manual.
P1117- O2 sensor heater circuit bank 1 sensor 2 short to ground
P1198- O2 sensor heater circuit bank 1 sensor 2 electrical malfunction
P1472- EVAP emission control LDP circuit short to ground
P1516- Intake manifold changeover valve circuit open
And the dreaded same code I've had the whole time........
P0102- Mass or volume air flow circuit low input.
I have also tried tracking down any bad wires, and testing resistance...
Golf IV / Jetta IV :: 2004 2.0 BEW Engine Stops Running

View 2 RepliesGolf IV / Jetta IV :: 1999 - Overheating / Fans Not Running
So my friend, ignoring my advice that this generation seems to be riddled with electrical problems, decided to purchase a seemingly nice 99 Jetta, with a junkyard AEG swapped in(AEG is written on the intake and block like a JY would do). Sun roof doesn't slide back, gets jammed, evidence shows water has built up previously and run down the A-Pillar to the fuse box.
I just got the fans unplugged and verified that the fans with power applied, both have their low/high speeds. The fuses on top of the battery are in-tact, no visible melting, looks like the thing is in ok shape(haven't taken them off to inspect the contacts yet).
Golf IV / Jetta IV :: No AC After Running For Few Seconds But Compressor Engages?
Weird A/C issue that started yesterday. Had ac on all morning, start my car after lunch, a/c runs for a few seconds, hear a squeak (like a belt sticking) no more a/c. Moving the temp knob makes no change just all hot air. Both fans engage, compressor and what I believe is the clutch engage, hoses get cold, and no CEL's. Really stumped here.
