Golf IV / Jetta IV :: 2005 - Overheats After Driving For 5 Minutes And No Boost?
Sep 11, 2016
i have a 05 GTI 1.8T and recently started overheating while driving. for a few months it would overheat if i idled too long but now after driving for 5 minutes it overheats and also wont build any boost. i could hear a hissing sound after i shut the car and thats coming from the flange where the coolant temp sensor is, but is hissing where is mounts to the engine.
update- i replaced the o-ring on the flange, that got rid of the hissing. the no boost must have been due to the engine overheating, but it is still overheating i guess im gonna check the thermostat next.
update 2 - checked thermostat and it is good so I'm at a loss here.

After running at normal temperature for about 10 minutes, my car starts to overheat. I noticed my radiator fan wasn't running at any speed, but my auxiliary fan was running fine. I checked the thermal switch and that was okay, because the auxiliary A/C fan still worked after jumping, and the big fan didn't. I replaced the fan assembly and now both fans work fine, so I assume that my thermostat is okay (maybe not and I'm missing something?). Even though both fans are running, my car still overheats, but maybe after 15 minutes now as opposed to 10. Water pump seems to be fine because I can see it pumping back into the coolant reservoir, and it doesn't seem to be sputtering or anything. Just replaced coolant recently after flushing with water, so I assume that the radiator isn't clogged. I also recently replaced the oil because it needed it anyway. It is still overheating so now I'm stuck. I can get to work and back because it's only a 5 minute trip and it doesn't have time to overheat, but I don't want to keep driving it obviously.

So if I let my car idle for more than 5 minutes the car starts to over heat. The engine fans do not turn on. I was waiting for wife and fell alseep in the car and it idled for about 20 minutes, I woke up to the audio alert and a red temp light in dash.
The temp was almost all the way to the right. I shut the car off for a few, restarted and drove and the temp went back to normal. Took home and checked for fans and neither of them are turning on. Assuming it is a switch or sensor issue.
So my question is did I do any long term damage by getting engine so hot? Taking to delaer tomorrow AM. This should be covered under power train warranty, right? If not how about certified warranty?

I bought my GTI used and don't know what software its running but I have some questions about the boost pressure. When I'm in Idle the car will only boost to about 7-10psi when i rev the engine in neutral, But when I'm driving it will boost all the way to about 17-20psi if I really stomp it, 15psi if I'm just giving it a bit of "go". The car takes off and goes really quick, seems like it has a lot of power so I doubt there's a boost leak but I'm wondering does the car boost differently in Idle because it knows its not moving?

I'm the proud owner of a 2005 MK4 1.8t gti, and recently it started making a weird sound when it starts kicking in to boost, where it would normally make a whistle sound while the turbo spools up it now makes a sound that reminds me of a supercharged car, it feels like it could be a leak but I don't have an ecl popping up, it does kind of platoes in the powerband, I hope I'm making some sense ..

Lately I've been hearing a constant click from what seems to be my chains side of the motor. Tensioners and chains were said to be done around 123k. After I've been driving it for a few minutes I hear the click. I thought it was the trans/ throw out berrying but when i push the clutch in and have it in gear i can still hear the click. It is not rapid like a tensioner like a tick tick tick, its like tick......tick......tick, could this be my top end of my block not receiving enough oil? I have a cracked oil pan, doesn't leak that often but i feel as if that is the source of the problem. Also I feel as if i lose power once i hit about 4300-4400 RPMs could that be because of low oil pressure?

So I have a 2001 VW Jetta Wolfsburg Edition, love the car. So here's my problem, whenever I am driving for more then 20-30 minutes my shifting between gears begins to become more and more rough, like whenever I shift from 2nd to 3rd, it directs me to first gear instead of 3rd and I have to kinda force it into 3rd. This only happens when I am driving for a long period of time, why this is happening? and sometimes when I put it in reverse I get a loud crunch noise but I get it into gear...

I have a mk4 Jetta 1.8t. Problem started last night. After I drive for about 15-20 minutes the oil pressure warning light comes on. It doesn't feel any different and my oil is full. Could my pump be going bad? I hear a slight tick near the bottom of the engine on the passenger side. But the car idles fine and drives fine too.

This only happens once or twice a week. After driving the car for 20+ minutes and sitting in the driveway, it will start running hot. I'd say around 230 degrees and it will stay there until I start driving the car again. I made sure the fans work and I also checked the coolant level and both are fine. What could be causing this issue?

I want to start by saying I'm new and don't really fully know how to search vortex, I'm sure there's probably a bunch of things about this. I have an 04.5 gli, my temp gauge reads 190 all of the time but according to vag com I'm running at about 220 some times higher. I've heard my fan kick in once in the year I've owned it. Also I get a decent amount of power loss after driving for about 20 to 30 minutes. Idk if that's related, but just hard wire the fan with a switch? I don't have a lot of money so I'm not really trying to play a guessing game replacing stuff.

I recently replaced the whole head and head gasket on my 2003 jetta 1.8t and it is still overheating so I have to replace either the thermostat, cooling fans, timing chain, or water pump. I have $700 and they said they can fix it for that. So should I spend my $700 and hopefully the problems go away or should I just try to sell the car as is and try to squeeze as much money out of it as i can?

I drive a 2005 Jetta IV 1.8T R-line. The engine shakes/vibrates at Idle and when I drive.
Also when if I drive at high speeds when I stopped the engine just switches off when idling.
What could be the cause?

My '98 4.0L Explorer Sport will begin to overheat if I'm in stopped traffic for more than 5 mins. on a hot day with the A/C on. I can correct it by turning off the A/C. Would a different thermostat work? If so, what temperature do I need?

my car into VAG COM and since then it hasn't boosted past 4 lbs. it has Revo stg 2, K04, aftermarket side mount, full exhaust and a couple other bolt ons. Before the car was spiking at around 23/24 lbs. after pressure testing the system I found that the turbo inlet pipe was lose, so I tightened it. Still no change. I tried holding the battery terminals together for 10 minutes to reset the ecu and I also tried clearing the codes through a handheld code reader. No codes even come up anyways for this. The car is a 1.8T.

I'm really bad with cars but I'll try to be as specific as possible.
Car: 2002 VW Jetta
Basically the car will just stall out of nowhere while driving (not stopped at a light), I would say usually about 10-20 minutes after I started driving. After this, when I try to start it, it makes that noise like it is trying to start but the actual ignition doesn't happen. it usually takes me about 15 minutes to start it up again.
In addition to this, when driving, the RPM seems to randomly drop off often, and the car also jerks frequently, especially when I press on the pedal quickly.

My 2005 Nissan frontier reeks badly.
Has new air filters and new cabin filters. Only seems to smell when driving at 55mph for about 20 minutes, the funk comes from the vents and in all heat/AC and fan modes seems to be less stinky in the winter.
Nothing is dead in the heater box because it does not stink in when driving around town and I have poured gallons of Lysol down the air intake during recic, open vent, etc, Smells like a mix of eggs, oil, and funk.
Dealership says it is not the catalytic converters as they "check out fine" Nissan dealership says it's bad gas, which is unlikely as when I drive away from home and I use other gas, it still smells.so what is it? What is it?

So my 2001 1.8t Golf is having some issues holding boost. I have a Gonzo stage 2 tune, CTS FMIC, Forge 008 Diverter, Silicone inlet and MagnaFlow Exhaust. I've also done the whole Evap, SAI delete and installed a catch can.
Starting in 2nd or 3rd at WOT the car spikes up to 18psi and then progressively loses boost throughout the rev range. Close to redline the boost drops to 5 psi or so. It seems to be dependent on the revs. In fifth gear the car holds 18 psi much longer as the revs don't increase as fast.
There are no CELs. I've done multiple leak tests starting at the air box and plugging the pcv/catch can system as well as at the compressor side of the turbo. None of the tests revealed a leak anywhere in the intake system. However, when I stuck my ear very close to the valve cover I could hear what sounded like a very small air leak coming from inside the valve cover. I took a look at the wastegate actuator and it seemed fine, no play in the rod, no loose bolts and to move it just requires enough force to compress the spring and it returned to its original position.
My thoughts are that it could be a fueling issue or turbo in the process of dying maybe.

Just noticed today that I have a slight drop in boost. Normal boost is 1.5 bar but today it is running slightly lower boost and does not have the same pull through all the gears.

I just recently notice a whistling noise when I hit boost. I'm not sure but it sounds like it is coming from my gauge. I'm not losing boost pressure. I do have a glow shift gauge. The most recent install was the TIP which I clamped on to the turbo but I'm wondering if it isn't on tight enough.
