Golf IV / Jetta IV :: Air Intake Temperature Sensor Missing?

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.

Golf IV / Jetta IV :: 2001 - Surging / Backfire And Missing

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.

Golf IV / Jetta IV :: MK4 GTI Exhaust Leak Or Possible Bolt Missing

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?

Golf IV / Jetta IV :: 2002 - Wire Harness Missing In Sunroof

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.

Golf IV / Jetta IV :: Steering / Suspension Assembly Bolt Missing

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] ....

Jetta - Volkswagen :: 3rd Gear Missing / Car Will Over-rev High In 2nd And Then Go Into 4th

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.

Golf IV / Jetta IV :: 2006 - Misfire Between 1200 - 1800 Rpm

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?
