Golf IV / Jetta IV :: Replaced Alternator Now VR6 Won't Start
After changing my dead alternator and resulting dead battery, I am having what seems to be electrical issues with my 2.8L VR6.
Neither of my keys can unlock or lock the car remotely and when I try to start the car, all the regular lights turn on in the dash, but the engine dosn't make a sound. Inside the car there is no power apart form the gauges, no windows, no AC, no sunroof, nothing. I have checked the fuses, unplugged the battery and plugged it back in, even changed the batteries in my keys to make sure that they weren't out, and nothing works. I have also tried to reprogram both keys and neither of them unlock the doors.
I think that it might have something to do with the anti-theft system, since I didn't touch anything while changing out the alternator.
Golf IV / Jetta IV :: 2001 - No Start After G68 Sensor Replaced?
Monday get CEL with codes p0722 and p0322. Car is in limp mode during these codes. Yesterday I change g68 sensor. Cleared codes, rough start but was sitting most of the week. Drove around fine, no limp mode, shifted fine. Started up a few times immediately after. Hours go by I go to leave and it won't turn over though it sounds its wants to. No clue why this is happening or what changing the sensor could have done. This is a 01 GLS 2.0 auto. Not sure where to from here especially since it drove so well afterwards.

I just got my timing belt replaced by my mobile mechanic thats been doing it for years. I saw him do the work and get the timing right. When he was done the car turned on and ran perfect. After about a minute the car just shuts off. Now the car won't start at all. The car turns over but no start. The car ran perfectly before I had this job done.

So i just spent over $1700 at a vw service ctr having a sched 140k timing belt replaced with thermo and fuel filter. This was 3 days ago and when i picked it up it was slower to turn over then got worse and todsy it won't turn over at all even when jumped. It cranks and blows black smoke. Problem is i'm 160 miles from that svc center and it's sunday. There is a vw svc center 14 miles away but i feel like it needs to ho back to where the work was done because it ran great before taking it there.

This weekend I replaced the transmission in my 2000 12v vr6 5 speed golf. Got In drive around block going through each gear all seemed fine. Then I tried reverse and couldnt find it. Seem like it reverse was more like 5th cause car would try and move forward. I have the new style shifter and the bearing is quite a bit beat up. However if I in engine bay operating the gears directly on shift paddle I still can't seem to find reverse. Is there some kind of lock out or what could I be missing. I tried adjusting the cables but that seemed to make things worse not better.

I just replaced my radiator in my vr6 jetta. I've replaced my coolant before, with this same problem,but it never affected anything and did not find any answers. But here's the deal. It filled with about 2 gallons of mixed coolant. No noticeable air bubble sounds, coolant flows back into the reservoir. I opened my top rad hose and poured coolant in also. It is not overheating. My heater is also hot, no problems there. It just seems suspicious that my car takes so little coolant, and runs just fine. I also flushed the system with my garden hose, and let all the water drain out.

So I replaced my thermostat today... to do that I unhooked the negative terminal of the battery, removed the hose off the thermostat housing (I think that's what it's called) and disconnected the switch to the alternator as well as take off the 13mm jam nut holding the wire to the side of the alternator. I reconnected everything up, put the key into the ignition and just turned it before starting the car and the alarm started going off. I disabled the alarm from controlling the lights and horn by unplugging the electrical connector just behind the fuse panel so I could do some errands today. I then disconnected both terminals on the battery and touched them together to reset the ecu.
After reading that holding the key into the door lock until the windows roll down would reset the alarm; this weekend I'm going to hook up my driver side door lock mechanism (been a little lazy) and give that a try.
Golf IV / Jetta IV :: Replaced Knock Sensor Still Sputtering And CEL On?
I replaced the knock sensor because I was getting the p0327 for the front knock sensor. Drove it again and still sputtering and CEL came back. What are other causes of this? N75 solenoid? Low fuel pressure?? It has a spectre air filter kit on it. Didn't know if this would do it. I cleaned maf. Just put new plugs in it too.

My friends car suddenly quit running while he was on a trip, he went through the carwash and as he pulled out the car died. He had it towed to a shop and they charged him $400 to run a few tests and replace the fuel pump relay thinking it would fix the problem, obviously didn't or i wouldn't be typing this. At this point the car cranks but won't start.
This is what the sheet from the shop says, "retest through PCM to locate problem. Ran diagnostics per flow chart. all power, grounds and G28 engine speed spensor output to ECM test good excepting pin T121/86, wire color Lilac/yellow. Signal between camshaft position sensor to ecm. No voltage signal recommend replace PCM and RETEST."
I've put a used ecm (ecu? i've read both terms used) in and the car cranks, starts, gets to idle and dies. If i give it gas after it starts it'll rev up once, then die. I'll call it progress, but i want this damn car out of my driveway.
Golf IV / Jetta IV :: Replaced Evap Box, Heater Doesn't Work
I just replaced my evap box along with most everything connected to it (had some bad servos and replaced other stuff for good measure). AC works great now, but the heater still doesn't work. I've had this car 4 years and the heater has never worked. When I took the box apart, the doors were naked (no foam). Heater core looked ok, but thought it would be stupid not to replace it while I was there.
So, I was hoping this may cure my heater issue, but was really only looking to get the AC going. So, the car had been running for 30-45 minutes and while the heater was on, I went to check the heater core hoses, the pass side hose was hot, the driver's side wasn't. Driver's side goes to axillary pump and bottom of coolant reservoir. Not too long ago, I replaced the mechanical pump and t-stat along with other stuff (crack pipe, etc.). Thought I'd get everything while I had the system drained. Didn't work then, either.
Golf IV / Jetta IV :: 2001 GLS VR6 Engine Lag After Water Pump Replaced
My girlfriend has a jetta and I work at a DODGE dealership in service. I recently replaced the water pump and flushed the coolant twice and replaced the coolant with G13 coolant from the local VW dealership. After I finished burping the coolant system of air bubble. After I finished I took it for a spin and being the speed demon I am, I don't hold back on the throttle. I noticed immediately the engine lagging and being extremely sluggish. I ran my shops snap on code scanner on it and I came up with cylinder 1 fuel injector open circuit. Cylinder 6 fuel injector limited power. And last but not least o2 sensor 1 open circuit. If your facing the motor I undid the left motor mount from the frame, lifted the car on a hoist and took the bottom side motor mount off of the motor. I took the cv shaft off of the transmission and lowered the car and jacked the motor up by the oil pan to expose the water pump for removal and replacement. I'm wondering if possibly the o2 sensor could cause the ECU to seize power to two of the cylinders to ensure no engine damage or if its 3 separate problems.

Keep getting o2 fault codes. Replaced sensors came back. tried another set of sensors came back. Checked wiring for breaks no luck. Replaced ecu still no luck. So going through wiring again and checking for continuity. Looking for a list of what pins to check for voltages, and what each should be from ecu to sensor connectors. Looking for what wire is signal and how to and what voltages to check for...

I have a 2000 VW Golf 2.slow. I have done some research from other threads but I'm wondering if mine is a simpler fix then testing all the wiring. After taking the car to Auto-Zone and having my battery and alternator tested they said the alternator was the problem. I had to wait a day to get paid to buy the alternator so I had them charge the battery. After I put the battery back in and started her up I got a flashing e-brake light, ABS light and no A/C. My A/C clutch compressor isn't kicking in either. I checked my brake fluid and it's fine as well.

View 2 RepliesGolf IV / Jetta IV :: Brake Fault Coming On Since Transmission Replaced But Never Before
I have a 2003 VW GTI VR6. Prior to replacing the transmission there was no brake problems what so ever. Since the transmission was done I get the "Stop Brake Fault" light on the cluster Intermittently. It never seems to happen when braking. I have new brakes and rotors on all 4 corners. As I said this only started happening immediately after the transmission was replaced. I did check the wear sensor on the pad to make sure it wasn't disconnected during the install. Where else should I be looking? Could it be triggered if they didn't bleed the clutch slave properly?

Last winter I had to replace my front passenger seat. The seat was starting to burn a hole or two, generally getting too hot for the passenger. At about the same time my airbag warning idiot light came on! I changed my front seat. The seat change was no biggy, but I keep getting the airbag light! Can this be cleared simply or only by a dealer?
View 8 RepliesGolf IV / Jetta IV :: 2004 - ABS / Traction Control Light Came On After Clutch Replaced
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?
Golf IV / Jetta IV :: 2002 - Replaced Water Pump And Thermostat Still Overheating?
My son has a 2002 Jetta, we just changed the water pump and the thermostat. The car will sit at idle and the temperature will stay around 190. When you drive down the road the temerature will rise and when you let off teh gas the temperature goes back down. What this could be, I have tried everything I can think of to fix this car.
View 13 RepliesGolf IV / Jetta IV :: Code 00281 - Replaced G68 Sensor But Still Only First Gear And Reverse Are Functional
I started my car the other day and found that it only drives the first gear and I can also put it in reverse. VCDS gave me a 00281 code saying no signal from Vehicle Speed Sensor G68. I replaced the sensor, but it still doesn't go into gear beyond 1st.
VCDS gives me the following codes after replacing G68.
2 Faults Found:
00652 - Gear Monitoring
27-10 - Implausible Signal - Intermittent
00281 - Vehicle Speed Sensor (G68)
03-00 - No Signal
I came across TSB 01-99-02 which says something about the codes being incorrect. It seemed a little vague about whether it is actually G38 or G22. I don't want to buy more sensors only to have it be something else. The speedometer and tach work fine so G22 doesn't seem likely to me.
The VCDS site says it could be several things including bad G68 or G38 sensor, low fluid & bad valve body. Was it the G38 sensor?
