Golf IV / Jetta IV :: 2006 - OBD2 Is Missing From Its Cut Out
May 10, 2014
I bought myself an 06 MK4 GTI and loving it!!!!!! But, now to the problem. OBD2 port is not in its designated spot. I believe the previous owner had an aftermarket radio in the vehicle and put the stock one back in before selling it. Is it possible they could have pushed on the wires and pulled the port out of its little cubby hole? If I remove the radio should I have access to the obd2 wires/port? IF so is there a trick for removing the stock headunit or do I really need the special tab tools?

Looking at my circle track car when they told me my air intake temperature sensor was missing this is a picture online I found: [URL] ....
The hole is filled with a bolt and some epoxy. I don't see where the cable is for it. What will this do to my car? It is a track only car.

I just acquired a 01 wolfsburg jetta 1.8t and first time vw owner.
I just got the car and found that all the pcv ventilation hoses were crumbling and broken down. I replaced everything under the intake up to the y at the valve cover. All was in stock at the dealer was the oil cooler elbow, tee and pcv valve. From there, i made my own hoses using 3/4 hose and couplers.
Before this, it ran fine but sometimes at idle the idle would jump up and down but not die. I also had a couple codes, can't remember what the number was. One was O2 bank 1 sensor 1 lean and i think the other was O2 related.
Now, after trying to fix the leaks. CE light went out but idle still does the same but my boost improved from like 5psi to like 9psi wot. That's not an issue but coming home tonight when i went to second, it felt like it was dragging or not wanting to accelerate or accelerate and like stall for a second. If you blip the throttle it back fires while in second when its doing this.
Only mod on the car i know of is it has a forge DV/blowoff i guess is the correct name. It can be used as a dv or both.

Brief back story, a year ago my timing belt went and had to replace the cylinder head and all associated parts. No problems since then, until now. Recently the check engine has come on, and got the code for an exhaust leak. Can't remember the exact code number, but the leak wasn't causing a lean condition or causing the engine to act weird so I left it until I had to time to find the leak. On the way home today I noticed an exhaust leak that got increasingly worse to the point where at a stop light I'd go to accelerate and it would pull away very sluggishly. Got home, opened the hood and tracked down the exhaust leak to somewhere around the manifold/downpipe/turbo area. I took off my cover and noticed what could be a bolt missing, and upon further inspection a bolt that may be coming loose.
Here's what I'm referring to:
- Missing bolt?
- Loose bolt missing bolt?
- Loose bolt?

So, I recently picked up mt 2000 vr6 has 200k on it runs great well taken care of. I was just driving not getting crazy or any sort of thing. it has ground in 2nd a little from when I got it. I put it in neutral then went to put it in 2nd and it went but nothing there. it will go into 2nd but won't stay and when I hold it in 2nd gear it just revs no noise or anything just sits and rolls. tried doing the reading but all I fold was 1st and 2nd I just have no 2nd.

I own a 2002 GTI and my sunroof was damaged beyond repair.
A local headliner shop had a used 2004 Jetta sunroof which he sold to me. The shop owner said everything was in working order with the sunroof except the wire harness that runs to the sunroof was missing the plug since it was cut. He recommended just taking the plug from my GTI sunroof motor and soldering it onto the Jetta motor since it may throw off the "timing" of the sunroof motor and would need to be recalibrated if removed. Keep in mind he is an authorized Webasco dealer so I took him at his word.
I cut my plug off of my GTI sunroof motor harness and began to solder it onto the Jetta sunroof.
I quickly noticed the Jetta sunroof motor had one extra wire (Brown). I didn't think it would be a big deal since my GTI doesn't have 6 wires and only requires 5 so I mounted the new sunroof with the Jetta motor onto the car.
The sunroof retracted back into the "fully open" position and would close but would not go into the "vent" position. Each time I would turn the dial to the "vent" position, the sunroof would slide back into the "fully open" position.
I thought this was a bit strange and now I am beginning to wonder if I need to swap the GTI sunroof motor on my car due to it not have the extra wire or is the Jetta sunroof motor going to work fine but another issue is causing this to happen?
Below are the differences in the two sunroof motors. Both are Bosch products.
Jetta Sunroof Motor - Part Number : GDO 849 696 564
This part has 6 wires that connect to it.
White, Green, Gray, Blue, Purple, and Brown
Where as the GTI has only 5 wires on it.
GTI Sunroof Motor - Part Number : GDO 849 696 566
White, Green, Gray, Blue, and Purple
The difference between the two is the additional BROWN found in the Jetta sunroof motor.

While changing the oil on my car I noticed that a bolt was missing from the steering or suspension assembly (not really sure what its for. I was wondering what it is for and how important it is. I went to the store to get a replacement and found that the threads in the hole have all rusted out so I can't get a new bolt in. Is this something I should definitely fix before driving again or is it not too serious.
Here is link for the pictures: [URL] ....

MK4 ... I have a 2002 VW Jetta 1.8T with that weirdo tranny (09A for those in the know) with the psuedo manual tiptronic VWtransmission. I don't think the tiptronic has anything to do with this, but here's my problem.3rd gear has gone missing. The car will over-rev high in 2nd and then BAM into 4th (and not, using the Tiptronic does not ameliorate, nor does using the 2nd to 3rd to 4th on the automatic shifter).
Interestingly, when doing tiptronic the car will reflect on the dash that it thinks it is in/going thru 3rd, but obviously is not. HOWEVER, When it rains, 3rd gear re-appears.I would not say things shift like a dream, but certainly not like the aforementioned nightmare. Up shift and downshift occur on time with an occasional hard shift.
My thoughts are that this is due to solenoid(s) conking out. VW says it is lifetime ATF and makes changing it next to impossible for an ape like me. Is it definitely something (solenoid or something else?)?

I have a 2006 golf mk4 GTI 1.8t and I've recently been having trouble with my low oil pressure light coming on. So the light will only come on when the engine Is hot and drops below 2k rpm but ONLY under 2k RPM. Why this is happening is my oil pump going bad.

I have an 06 Jetta VR6 and it's making a lot of power steering noise (humming and howling). Is steering pump failure common in these cars?

Vehicle: 2006 Mk IV Golf 2.0 GLS With 82766 mi
Back story: I purchased the vehicle from my dad who did regular maintenance except that somehow spark plugs and wires slipped through the cracks until now. A few months ago (while I was in training) it apparently started showing CEL but the few times it came on, my wife said it just disappeared. Two weeks ago, it came on again and I had the code read which came back as P0420. I took it in and they replaced the rear cat after which it ran well for a few days. Then the CEL came on again but went off before I could get out in the shop. This weekend I went ahead and changed the oil and may have over filled it slightly. The next day I went to change the spark plugs and after changing 4, 1, 3 it started to miss fire in 4 and 1. I reset both spark plugs and got 4 firing again, but 1 remained bad. With a friend I determined there was a weak spark in 1 and changed the wire but no change.
Current situation: As it stands now, it's still miss firing. The worst seems to be between 1200- 1800 rpm and if I keep it above there the light will stop flashing and even turn off on some cases. I've read that heart mixed with moisture(I just moved from AZ to WA) can lead to a cracked coil pack or that the injectors can go bad. Should I just take it to vw specialist?

I have a 2006 Jetta and can not open my 2 back doors either from inside or out. You can hear the electronic locks lock/unlock, but doors will not open. Took it to the dealer and they said " Testing found FRONT door latches have an internal open circuit malfunction. They want to replace switches.

I've found lots of good resources here about disabling the backup beep with a bluetooth OBDII device, but I don't have access to an android phone. I have a windows 7 laptop.

Getting an intermittent power problem at about 50 to 55, could that be a spark plug or timing or possibly a fuel problem?

My Toyota Tacoma is reporting (via an affordable OBD-II scanner) the same P0420 code: First as a regular code, then as a pending code. What could that mean?

Today I bought an OBD2 scanner and was trying it on my 2001 accent but the app on the cellphone ( torque ) said : " couldn't connect ECU " . I think there is no ECU in my car, any example about trying the OBD on a 01 accent ?

I hookup an OBD2 tester on my Prius 2014 Plugin and saw the OBD2 P0300 - Random Misfire. I did a reset and the error still came on. I also tested my friend Prius 2014 Plugin which is factory stock and had the same error. Wonder if that is by design or not. Going to take my ride into the dealer on Friday for my 25K maintenance and have them look into that error. P0300 can be anything. Hopefully doesn't cause more problems down the run..
