When it's cold out, sub-60F, the car won't turn over when the key is turned to start. Eventually, after repeated attempts, it will turn over and start like normal. My battery is fairly new. My first guess would be a starter relay issue but according to the manual I have there is no starter relay.
View 2 RepliesIs it normal for my 2003 Jetta 1.8T to have trouble reaching operating temps from a cold start when letting it idle in the driveway with outside temps of 30F?
I recently had my thermostat replaced because my coolant temps never reached operating temps even when driving on the freeway.
Now with the replaced thermostat it reaches close to 190 after around 10 minutes of driving but if I am starting a cold engine and stay idle in the drive way it will not heat up to 190 even after 10 minutes.
When I tried a cold start with just letting it idle in the driveway for 10 minutes my check engine light came on giving me the P0118 code which I had before I changed my thermostat and a P0411 code.
After getting the thermostat changed I drove 100 miles to a destination and 100 miles back home the next day. A few days later I drove 22 miles to pick up a friend then 22 miles back without the check engine light coming on.
It was only when I let the car stay in idle from a cold start for 10 minutes that the check engine light came on and gave me the two error codes of P0118 and P0411.
Now I suspect the P0411 is from a leaking secondary air injection hose but the P0118 code confuses me as I switched out the thermostat and the coolant temp sensor.
So my oil light was blinking on 03 jetta 1.8t for a week or so because of the cold temps where i am once my car reaches temp if you turn off the car and turn it back on my light stays off. i had a oil change recently hubby did that plus i had all my fluids checked and had to have my dipstick tube replaced because it broke.
I had a mechanic who lives in my complex take a look at the car and he said everything is running fine. So today I started my car then my oil light went on again it has been a lot colder than the past few days could that be the reason? My cars not overheating at all but once it gets to temp if you shut and turn the car back on the light goes away. My car only has 88 thousand miles on it and we used the proper oil for the oil change..
My car is a 2003 Jetta GLS 1.8t. It has 223000 miles, yet other than normal maintenance it has never had any real issues since I have had it. However, maybe a week and a half ago when I got up to go to work the car wouldn't start. It would turn over, but would never actually start. When I got home from work later in the afternoon I tried again and it was fine. It's been doing this and progressively getting worse ever since.
If I go to start it in the morning, nothing. Wait until 10-11 or so and it'll run in one attempt. What's strange is that temperature does not seem to affect this issue. Some nights I will go out to drive after it has cooled down outside (70 degrees or so) and it will start no problem. Some mornings it's already 80 degrees and I still have no luck.
I have pulled the following DTCs, which keep reappearing after I clear them, making me believe this is an electrical issue:
P0261, P0267, P0270, P0264, (all 4 cylinder injector circuits low) P0445, P0037, P0418, P0010, and P0414.
So far I have replaced both the Secondary air injector relay and ECM relay, pulled and checked every fuse in the car, cleaned the battery terminals, and am about to go out and check every ground.
I am having a problem with my MKIV, @ 182k. I think problem first arose a couple months ago when reverse began not engaging on cold starts, so I would have to sit there 5-10 minutes waiting for car to 'warm up' enough for reverse to engage. This led me to taking it to a local tranny shop who I asked to change fluid only, which they did. Problem persisted however, but forward driving was noticeably much smoother. If that matters. I gave up on it, since I knew it was only reverse messing up, and started parking in reverse overnight etc.
Simultaneously I had a code for P0420/P0411 (the SAI incorrect flow crap which causes catalyst inefficiency) so I went ahead and swapped out the cracked SAI plastic hose leading to stock airbox, after doing so I reset the CEL and ran the car. And it ran like crap, I think it was in limp mode (i had never experienced this in my Jetta) from what Ive read, but not sure. So, I pulled to the side, and restarted car, let it sit, same problem. Finally, after 3-4 cycles it threw a CEL, which ironically FIXED the problem. It ran fine from then on. Made it home, hooked up scanner and CEL code was P0732, which I read elsewhere is a 'Gear 2 - Incorrect Ratio' meaning 2nd gear is messed up somehow.
So, overnight I reset CEL and today in the morning I let it idle for 10 minutes before taking off, immediately same issue, where car will not accelerate/ change gears it seems. Went back straight home, waited for CEL to display, and VOILA, runs fine again. Same code P0732. Running fine as of writing this. Problem only arose after taking a swing at SAI code and reset of CEL's. Once CEL lights up its fine.
My 03 Golf ac is not working and i am looking for a wiring diagram/ troubleshooting chart. the cooling fans turn on low and I hear the engine surging like the compressor is trying to cycle but it is not.. When I jump the low pressure switch the fans go to high and no power to the compressor. I get a flash of power to the compressor but just a blip every ten seconds. I am trying to check continuity of the ac clutch but having a difficult time getting in there hot. I just bought the car and fixed light body damage on the right front but it was not even bad enough to hurt the washer bottle. Hard to believe the hit caused damage to the ac? AC seems to be charged with about 100 psi static pressure. Why are diagrams so hard to find?
View 2 RepliesI wanted to find a way to turn off my daytime running lights on my 03 jetta. I found a video that said to tape off the pin in the light switch in the interior of the car.

View 2 RepliesI would like to start off by saying I am new to this forum. I bought a 2005 Jetta GLI a couple of months ago and from the first day I noticed that occasionally when I would lock it with the alarm, the right turn signal would stay on. It was not much of a problem as I would just press the lock on the remote again a couple of times to turn it off. Lately it has become more frequent and annoying. I have to wait up to an hour so I can finally turn it off through the remote. I was thinking the relay probably.
View 15 RepliesMy air conditioner is not getting cold. The fan is running, and the AC light is coming on when i turn the dial. Also, the compressor is working and the clutch is engaging. I checked the fuses inside the car and the fuse above the battery.
View 3 RepliesI have a 2000 Jetta that doesn't blow cold AC. Here are the details:
- When the AC is turned on, air does blow through the vents. Each setting (1-4) does blow harder than the previous.
- Both front fans spin and are working
- The AC compressor clutch never engages
- All fuses (two inside the car and the one above the battery) have been replaced and test good.
- When the AC is on full blast, the voltage coming from the AC compressor wire shows ~9.3V for about 5 seconds, then jumps up to about ~11V for less than a second, this repeats over and over and the clutch never engages.
What the next logical troubleshooting step would be? I've read about this possibly being the fan control module (maybe) and also read about testing the AC compressor using an external 12V power supply, but am not sure where to go from here.
Is it a good deal to buy a 1.8t jetta with transmission problems. Won't go on reverse when the car is cold. 1500? mk4 vr6 .....
View 10 RepliesI have an 01 Jetta 1.8t wolfsburg eddition and the AC won't blow cold air. The AC Clutch does engage when I press the AC button on the control unit The refrigerant pressure is good The fan blows, but its hot air. the condenser is working because the pipe is cold when the ac is running I am curious if any of you know what other possible problems could be causing this. It is currently 100 degrees with 100% humidity
View 11 RepliesI have a mk4 gli and the a/c is not blowing cold, or remotely cool. When I turn on the a/c the engine drops rpm's like it is engaging, or whatever, but doesn't get cold. I checked under the hook and it sounds like something is trying to come on every 10 seconds or so...it's like the engine jumps or something. The fan on the passenger side is coming on if that means anything but the driver side doesn't when a/c is turned on.
View 4 RepliesStarted noticing an issue with my trans awhile ago, the other day it stopped shifting out of first when cold. It's a 1.8T auto 5 speed tiptronic, it's the Jatco 09A. I know the shifting problem is the solenoids and it doesn't look that hard to swap them out. The trans shop said it looks like there is slippage on gears 2-4 and the fluid is toast. Looking at replacing or rebuilding, shop said 4-5 grand, how easy would it be to swap in a used trans? And what kind of issues would I be looking at?
View 1 Replies'01 Jetta IV GLS AC not blowing cold air:
1. Blower works on all 1,2,3,4 settings
2. Cabin Air Filter Clean
3. When AC button pressed, I see the Compressor turns and noted the clutch also engaged.
4. AC Fan near Radiator comes on
5. Blend Door seems to be working fine - fixed the problem of spitting foam without opening up the heater box.
6. Since the above electrical parts seem to be working, I suppose it could not be a relay issue.
I have 2002 1.8t jetta 5spd with 200k KM, last winter it was difficult getting into gear when it was cold. the fluid has never been changed, so that might be the issue.
View 4 Replies having the issue where there aircon refuses to work even if the system is gassed up and leak free, and the compressor seems to be functional but not powering up. Before spending loads of cash on controller units, swtiches etc, your problem might be a dodgy connector under the battery tray.
As I have bought another Golf that appeared to have this issue, I took some photos this evening while I fixed it, hopefully this will be of use to people?
To start with, I had a look at my old Golf, which I knew had already been repaired. under the battery tray I found the repair. I put new tape on as the old tape was showing its age, so it shows up quite nicely - it's the blue tape!:
and a bit of a close up:
So now I knew what I was looking for, I had a look at my new Golf:
Which, I cut out, soldered the ends together, heat-shrink wrapped, then covered with some more trusty blue tape and zip tied it all up to try to minimise further chafing (the blue tape on the left is another part of the loom that looked like it needed a bit of tidying up):
A drive around this evening shows the aircon is now blowing a lot colder than before (previously it was blowing hot air after 5 minutes). I'll be testing it properly on a hot day, but I'm 90% certain I've nailed it.
I am trying to narrow down what could be the issue to my 2002 vw Jetta VR6 air conditioning. It is blowing air but the air is not cold. If I need to add refrigerant, where I can find the low pressure valve so I can do this on my own with one of those store bought cans.
View 2 RepliesI have a 2003 Jetta. It runs great until it just stalls out with no warning. There doesn't seem to be any particular thing I do to make it stall. I could be accelerating onto the highway, just driving down a residential street, moving along at 60 mph, or just starting out of the parking lot. It happens when it is cold and when it is hot. It could happen twice in one day and then not for two weeks. I have taken it to the dealer, a VW specialist, an excellent auto electric specialist, and the local mechanic. No one can figure it out. I have so far replaced the fuel pump, ignition wires, distributor, several engine sensors, complete tune-up, all filters, battery, and some misc wires and hoses. All told, I have spent over $3000. replacing stuff and trying to cure this car's ills. The dealer could not get it to duplicate the stalling. No codes have shown up at the VW dealer, the local guy, and Autozone. The auto electric guy drove it over 100 miles on one week with no problem, then it stalled on him. He immediately hooked it up to the diagnostic machine....and no codes! He was perplexed.
View 7 RepliesMy 120,000 mile 2003 VW Jetta will not start in cold weather. It starts fine when the temperatures are in the 30s, sporadically in the 20s and not at all in the teens and single digits. When I turn the key, the engine does nothing; it does not crank. Three mechanics have not been able to figure out the problem.
