Golf IV / Jetta IV :: 2000 - Intermittent Grinding On Start Up
Over the past few weeks my 2000 Jetta GL has been occasionally been grinding on start up. The car starts fine, but it sounds like the starter doesn't realize that the engine is running and it makes that oh so lovely grinding noise for an additional half a second or so. It doesn't do it every time, just when it feels like being ornery. Is the starter going, or what?

2001 Jetta 2.0, manual trans
I've been having problems with intermittent P0420 cat below efficiency code. Everything else is fine, no codes, runs great. I tried spacing the post cat sensor back w/ extender bung (after replacing post cat sensor..) and still get the code. I don't hear any rattling or anything to make me think cat is bad physically. I was told by dealer that a code update might resolve for $200 - which got me thinking that that if that was so, it should should be a problem which Feds should be aware.
I searched safercar.gov and found this NHTSA ID Number: 10054864
It's a service bulletin saying that VW made the limits too sensitive and it seems there was a customer satisfaction campaign to update code - pdf on site CSC-10054864-8736
It says:
May 2007
Subject: Emissions Service Action N7
1999-2002 Jetta, Golf and GTI with VR6 Engine
Update Electronic Control Module (ECM) Software for Catalytic Converter Monitoring System Dear Volkswagen Owner: We are writing to inform you of an emissions service action on some 1999-2002 Jetta, Golf and GTI VR6 engine vehicles. Our records show that you are the owner of one of these vehicles.
What Is The Problem? The electronic control module (ECM) software for the catalytic converter monitoring system is too sensitive. This can cause the MIL to come on, and some vehicles may exceed Federal and/or California emissions standards. Also, in some cases this leads to unnecessary catalytic converter replacement. What Will Volkswagen Do? Dealers will update the ECM software.
Golf IV / Jetta IV :: 2002 2.0L 5 Speed - Intermittent Crank No Start
I have a 2002 2.0L 5spd Jetta that has an intermittent crank no start issue. The car has about 140k miles on it. The car will crank, but will not always start. It seems to start about 8/10 times. During the cranking, there is a rough noise coming from the starter area. More on this noise later.
When the car starts, no codes are thrown. When it refuses to start, the following codes show up:
P0261 Cylinder I Injector Circuit Low
P0267 Cylinder 2 Injector Circuit Low
P0270 Cylinder 3 Injector Circuit Low
P0264 Cylinder 4 Injector Circuit Low
P0445 Evaporative Emission Control System Purge Control Valve Circuit Shorted
P0037 HO2S Heater Control Circuit Low B1S2
P0418 Secondary Air Injection System Relay "A" Circuit Malfunction
P0420 Catalyst System Efficiency Below Threshold (I don't think this is related to the intermittent starting issues)
I've read up on these codes, and there are instances of other people getting these codes as well, but unfortunately, I haven't found any "smoking gun" that's the root cause to solve the issue. What I've tried, chronological order; none of these solved the problem:
Checking for spark. The spark plugs are new (within 2 months), but I removed spark plug and checked for spark.
Check fuel system: I removed the fuel line to the engine and drained it to a jug. I saw fuel flow intermittently when I keyed on the car. (Should it flow continuously?)Replaced the fuel filterSwapped fuel relay 409Checked wires near relays for obvious signs of damage (admittedly maybe I missed something here)Swapped coil pack. The coil pack was replaced in April, but I put a different one on, to no avail.
The spark plug wires were replaced at the same time as the coil pack.Starter
Thought fixing the noise might fix the starting issue. The noise from the starter is a grinding noise that occurs during the cranking process (not after, as is a common problem with these Jettas. It's NOT this noise: [URL] .... In any case, I tried the fix for the above noise by removing the starter and regreasing the inside. That didn't work and the noise and the intermittent starting issues are still here.Finally took the starter to Advance Auto Parts, had it tested, and was told it was good.
I think I have two issues that may or may not be related- the intermittent starting issues and the noise issue. They started happening at close to the same time.
Golf IV / Jetta IV :: Code P0441 / Intermittent Gas Cap Light
2.slow bev engine / 2004 golf gl / 105k miles
The car sat in a garage for 9 days. It had no problems before. Now I have a p0441 code that comes back after being cleared, and an intermittent gas cap light. Is there a typical problem that causes this?
Golf IV / Jetta IV :: ABS Light Came And Went / Red Exclamation Mark With 2 Intermittent Beeps
So I just got new pads and rotors for the front on my 2000 Mk IV, drove smoothly...
Then about 1 week in today, my ABS lights came on.
I turned it off, left it for about 2 hours then turned on the car again, Got a red exclamation mark that made 2 intermittent beeps together (twice), then the ABS light went off??
Still drives smoothly? faulty assembly?
Golf IV / Jetta IV :: 2005 - Intermittent Check Engine Light
2005 Golf TDI... I'm due for a smog check, and of course, in the last few weeks I've been getting some check engine lights intermittently. I'd rather take care of the problem before trying to smog. Anyway, here are the codes.
Confirmed
P0674 - Cylinder 4 glow plug circuit/open
P0673 - Cylinder 3 glow plug circuit/open
Pending
P0101 - Mass or Volume air flow "A" circuit range/performance
To be honest, I haven't learned all that much about my Golf TDI. Just normal maintenance. So, I don't know where to start.
Golf IV / Jetta IV :: 2000 GLX - Intermittent Start And Stall / Pending Code P0321
My wife drove the car to work, and it ran good. She got a check engine light, but it was not on when I got home from work. I started the car and it idled fine for a couple of minutes and then it stalled. I check the codes and there was nothing locked in. There was a pending coding P0321. I am not sure what a pending code is, but I assume not enough to trigger the check engine light.
After work each night this week I tried troubleshooting but I have not gotten anything accomplished. Each night the car would start fine but if I turned it off it would not start until many tries if at all. It turns over strong but won't start. I drove it around the neighborhood today and it stalled and wouldn't restart.
The fuel pump primes. When the car won't start the fuel pump relay clicks constantly. Is this normal? I replaced the fuel filter because it has been 50k miles. Is the crank shaft sensor the problem? I hate to throw money at parts that aren't the problem when I can't get a code to trip the check engine light.

I have a 2001 GTI 1.8T, and it's refusing to start. It turns over and all power accessories work, so I've ruled out that the battery is dead.From the bit of research I've done, I wonder if it's a fuel issue or something to do with the coil packs.The only thing to be mentioned is that about 3 days before this occurred, I left the headlights on while I was away from the car. A quick boost and that problem was solved. I wonder if this could be related at all.

I have a 2001 Golf GLS that normally starts on a dime.
It's already had replaced:
New Starter - 11/2/12Ignition Coil / Plugs - 5/22/13Rebuilt Alternator - 5/9/14New Battery - July 2015
The other day, nothing happened when trying to start her, no cranking or anything. The lights work, battery is good.
Yesterday, I depressed the clutch all way to the floor and it started.
Not sure if it's related, but I'd like to trouble shoot before I take it to a shop who's going to want to replace everything.
Car has 154,445 miles. Not original owner, so don't know how they drove it. We got it with 150k
Golf IV / Jetta IV :: 2001 - Won't Start When Turn The Key
My 2001 Jetta GLS V6 automatic won't start. Turn the key, lights come on bright, nothing happens. No sound other than a single click. Problem started tonight while running errands. Made many trips today without problem. Last stop at the grocery store, no start.
89,000 miles. Only problem of late is the trunk latch mechanism broke. Have been using the key to manually open. Could I have messed up the key fob? Going to try alternate keys when I can get back to the car in the morning.
More info: our mechanic managed to start the car today, playing around with the gear shift. Got the car home and into the garage, but now won't start again. He thinks it might be a problem inside the console, with the gear shifter. ?? Doesn't know if he will be able to fix it or if he will have to send us to the dealership, which I would like to avoid.
I tried both of the key fobs and the valet key. Checked the fuses on the side of the dashboard. When key is turned all the way to the start position, 3 lights remain on the dashboard: EPC, Check Engine, and Battery.
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.
View 4 RepliesGolf IV / Jetta IV :: 2001 TDI Clicks Or Grinds With No Start
2001 Jetta 1.9 TDI that won't start! For the past few months, starting the car has been hit or miss. I started by changing the battery, later the starter, then later the glow plugs. Each item seemed to get it start. When I say "hit", the car started fine as long as it was plugged in when cold. And "miss", the car clicks or grinds with no start.
After I changed the glow plugs it didn't miss at all for a couple weeks (the outside weather has been getting warmer too). Then it started missing on and off, and now wont start at all.
Here is a video - the sound it makes during the second attempt (clicks then winds) has been common since not long after changing the starter. [URL] ..... The car is being boosted during the video.
Some extra information: about a month ago I notice the coolant was a little low (added less than a cup of G12), a few years back the car, had some half diesel and half gas ran through it. The car has 350,000 kms..
Golf IV / Jetta IV :: 2001 - Won't Start - Ignition Switch?
Just got this car it's 2001 gti turbo. The guy said that the key fob was back. But I changed the starter and still no luck. It had all new plugs and I went to check for spark and there was no spark or fuel. So then I got a new crankshaft sensor and still no luck. I haven't gotten the chance to check for spark yet. And now those lights and beeping keep happening even without the key In the ignition. Can it be the ignition switch or something worse?

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 - Light Stays On Even When The Key Is Off
Even when the key is off this light is on. The rear defrosters are not getting hot, and when you turn the car on and use the defrosters the light will brighten. It happened to my car while it was sitting in the school parking lot.
The cause of this problem I assume is a short in the wires going from the c pillar to the hatch.
[URL]................
I just put the rubber cover back on them and the light turned off. Insulation on some of the wires was cracked and falling off. I will fix the wires with either electrical tape or new wires depending on the condition when I am able to do further inspection
Golf IV / Jetta IV :: Randomly When Go To Start Battery Is Dead 2001 AWD Not Starting
I am absolutely stumped and so are two mechanics I've been to. Randomly when I go to start the car the battery is so dead it won't start. Car is an AWD 2001 1.8T Jetta.
Replaced battery and alternator at my regular mechanic, all ground wires look great and couldn't find any shorts. There is a 11 Amp draw from my battery, took it to a shop that specializes in VW/Audi and they hooked it up to Vagcom and it showed absolutely nothing wrong. He left the meter hooked up and pulled every single fuse in the car and there was only like a 0.01 drop, nothing significant. When he went to take my car out of the shop, wouldn't start. So he put a battery pack on it, still wouldn't start. Took off both terminals on the battery, put them back on, put on the battery pack, and car started.
The aftermarket deck in it is just a JVC single din, doesn't seem to have any issues.
Golf IV / Jetta IV :: 2001 - Battery Dead - Sits For 10 Minutes Then Start Again
I have an 01' 1.8 t. We had a Pioneer touch screen Bluetooth deck installed and it was fine for months. All of a sudden it started having battery problems. If it sat for 6+ hours it was dead. We got a new battery from pep boys and once again it was fine for months. They tested my charging system and all components and everything was good. Then it started dying again. We'd charge it and after about 10-20 min it would start. Now the sit time is sporadic, sometimes it will sit all day and start right up and sometimes it sits for 10 min and won't start. Now its not taking a charge. We've once again checked the terminals, charging system, alt. Etc. And its all good. I don't know if it has anything to do with the stereo. We've checked all the wiring and its how it should be, I'm at a loss with this car. It occasionally throws a check engine light but we've hooked up the OBD and there's no codes. When I run the ac the car acts super sketchy, and starts throwing lights. (Brakes, air bag, wipers, engine, asr, doors). Fuses checked out all good, we haven't been able to find a single diagnostic explaining wtf is going on. I love my car too much to give up on her.
