Golf IV / Jetta IV :: Won't Boost Past 4 Lbs?
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 have a 2001 1.8t. Was stock except for exhaust and Cai. This weekend I installed a Audi K04 turbo, Audi exhaust manifold, 3" down pipe to 3" exhaust, 3" maf, front mount intercooler, 3 bar fuel pressure regulator, high pressure fuel pump, 386cc injectors, r8 coil packs, ngk plugs. The car start but sounds like it's going to turn off and can't get it out of first gear. As soon as I put some gas it seems like it chokes and can't go past 10 MPh. I don't have it chipped could that be the reason or should I look at something else that could be causing the problem. I'm wanting to go Unitronic stage 2+ but don't wanna do that and still have the same problem.
View 1 RepliesGolf IV / Jetta IV :: 2001 2.0 Wagon Won't Rev Past 3200 RPMs
The wife's Jetta wagon has been giving us some issue. It is a 2001 2.0 AZG engine auto trans wagon. 195,000 highway miles and well serviced and taken care of.
Here is the symptom : Engine will NOT rev over 3200. It will hit 3200 and stop dead. This is the case either in gear and driving or just sitting in Neutral. The engine seems to take a bit longer to start but does every time. The car seems to run great other then the 3200 rpm ceiling.
Wife has been driving it around like this for a while and I have let the codes accumulate. Here is the codes it gave me.
16727-cam position sensor- I just replaced the CPS with no improvement, issue is still there and code still pops up. I was told this code comes on when the car does not fire on the first rotation anyhow so it could be something else.
16804-cat o2 bank 1
16990-ICM issue
Cleared the codes and restarted the car. 16727 comes on immediately but other codes take a while to come on again.
I am leaning towards maybe an electrical issue? Bad ground, alternator output or something. Any tips on places of ground, connectors etc to clean and check? Also one or two guys keep mentioning coolant temp sensor and crank position sensor...but wouldn't those toss a code too?
I also pondered a plugged cat but I dunno, have had that before and you can usually tell right away...the car runs great until it hits 3200 and it is like a governor kicks in and she stops dead at 3200.
Golf IV / Jetta IV :: 2001 / 1.8t - When Accelerate Boost Won't Go Past Zero And Stutters
Okay I have a 2001 Vw Jetta 1.8t Wolfsberg.
I have done a few mods:
- Oil catch can
- Boost gauge
- New turbo (5000 miles old)
- Brake booster mod
- PCV system fixed and some hose deletes (that make the intake manifold have one line off of it rather than two)
- Timing belt/ pulleys
- Accessory belt / pulley
- A few other things but nothing to cause this
The car will do this randomly. And I mean once every two weeks of that. I will go to accelerate and the boost gauge says the "boost" is at zero and no matter how much I give it gas, it won't go past zero and stutters. But it stops almost as fast as it starts. I don't get it...
My catch can has 3/4" line to about 1/2" or so, that meets the oil catch can. (Ebay with the blue hose.) I have new plugs, all new (dealership recommended) lubes, all kinds of new small odds and ends. But it's never done this before. (3rd time now in a month..)
Golf IV / Jetta IV :: 2001 - No Power And Won't Go Past 3000 RPM At 20% Throttle
I made an earlier thread about minor low speed crash and airbag deployment that has sense been fixed.
The engine 2.0 (AZG) will rev to 3000 (3200 sometimes) RPM and stop. This is only if you give it about 20% / 25% throttle. If you give it full throttle it spits and sputters. When I had the airbags installed. The codes were read it and also came up for cam sensor and o2 changed that and now the codes are gone. No CEL and it is exact same issues still. I can't tell if ECU is doing it but it feels like it's not getting enough gas or air since full pedal makes it stall.
Golf IV / Jetta IV :: Chokes The Power Past 3500 RPMs And Continue Running Rough
I own a 2001 Jetta GLX 12v VR6, lately the car has not been running well. It chokes the power past 3500 rpm's and will continue running poorly and sound sort of like a Subaru boxer engine. Sometimes it corrects itself and runs okay but goes back and forth.
I ran the codes on VAG COM:
6 faults found:
17551 - Load calculation cross check
P1143 - 35 - 10 upper limit exceeded - intermittent
16712 - Knock Sensor 1 (g61)
P0328 - 35 - 10 Signal too high - intermittent
[Code] .....
I ran VAG COM a couple of days before these codes came up and I had a different code dealing with air/fuel mixture, something about fuel running to rich. I'm stumped.
Golf IV / Jetta IV :: Speedometer Reading Accurate Only Till Around 45 Mph
My speedometer reads accurate only till around 45 mph. The needle begins to float around gently, and the faster I go, the more discrepancy it reads. It may hang a while, floating around 60 and the speedometer app on my phone says I'm going 74.
The speed sensors were replaced for another issue a year and a half ago. The dealership initially wanted me to put a new transmission in it for $3800 after they said the trans was slipping past 45. Then they said something instead about a valve plate (could be wrong vernacular) for $1000 instead of an entire transmission.
When I finally told them that my cruise control is completely erratic, trying to track the needle movements with upshifts and downshifts, they said it's $200 in parts for the drive gears and that they were made with plastic that can wear out.
So I said I would sit on it, since the ideas about the issue seem to vary greatly, and my father set me up to go to a transmission shop to have the car checked out. They had it for two days and changed the fluid out but we can't fix your speedometer issue... take it to the speedometer shop, but btw we think your transmission is fine.
Now, do I take it back to the dealer for the drive gears, or do I take it to another specialist? I have seen people say all it needed were the drive gears replaced and a new sensor. My odometer seems to still be working. There is no issue with my gas gauge.

View 2 RepliesGolf IV / Jetta IV :: 2000 - Coolant Gone - Speedometer Fault Code Came On
This morning, I wanted to drive to work, but all of my coolant was gone. In the last couple of weeks, I had some errors with my speedometer and had it replaced a week ago, which did not fix my problem (the P0722 sometimes still came up).
Could it be that my coolant leaked over the last weeks and somehow messed with my speedometer, or are those most likely independent errors?
My car is a 2000 Jetta VR6 and at this point I don't want to put too much into it any more. If you need more input, let me know.
Golf IV / Jetta IV :: Error Code P0501 Even If Speedometer Is Working
My car (jetta 2002 1.8t) have the error code p0501 even if the speedo is working. I replaced the speed sensor just to make sure.
If I erase the code, and drive no matter how far/fast I go, the check light doesn't turns on. But as soon as I turn of the car and drive again it does comes on.
Golf IV / Jetta IV :: Speedometer Needle Stuck And Not Counting Miles Correctly?
So my girlfriend got a 2002 Jetta Wagon 2.0 automatic (PRND321, no tiptronic). She noted when she was driving fast on the driveway highway one day her speedo stopped climbing and would wiggle around 60mph and not go any further even if she was going 80+.
I would have thought first that the speed sensor would be messed up. Went to the junkyard and pulled 2 speed sensors for cheaper then 1/4 of new. Put the newer cleaner part on and the same exact issues. Locks up and wont climb past ~65mph and the needle wiggles. I am guessing its not the sensor. Question is what could cause it? Could it be the actual internal gear in that meshes with the transmission? Ill try replacing, i have extra i think. But could this be a cluster or a computer issue? And the odometer is also off. When it gets stuck at the slow speed, the mileage won't count at the full speed. She drove to a friends at a known 80 miles away and it only said its was low 70-something on the gauge when she got there. So there is a discrepancy of mileage count too.
I am going to head to the junkyard soon and thinking of pulling a cheap cluster to try it out, but I also heard you might need a VCDS for the immobilizer in the cluster. And the mileage is stored on the cluster or not? What should I pursue next?
Golf IV / Jetta IV :: Speedometer Doesn't Work - Gas Gauge Moves Around Bends
So the other day i hit something on the road and all of the sudden when im coasting in gear i hear a "thududududududd" noise from mid engine.. you cant hear it when the windows are down, only when they are up and it doesn't happen in neutral or when the clutch is pressed in. also after i shut the car off and turned it back on i had a CEL for the A range vehicle speed sensor which i replaced yesterday but still the speedo doesn't work and the gas gauge is moving around bends. when letting off the gas to shift the car stops almost like hitting the brakes and shifts kind of hard. It also backfires like a shot gun in 4th gear only. I recently had a stage 2 south bend clutch put in but everything was fine after that installation.
View 1 RepliesGolf IV / Jetta IV :: Speedometer Stopped Working / Cruise Control Does Not Work
I am proud new owner of a 03 Mk4 Bora GLI. I have some issues that I could use a hand with. My symptoms are as follows:
1. Speedometer stopped working.
2. Fuel gauge goes on the fritz (rapidly declines) when parked on an incline or going around corners.
3. Cruise control does not work. "Cruise" light come on the dash but the set/reset button on the stalk does nothing.
Note: All fuses are in tact.
Golf IV / Jetta IV :: 1999 - Instrument Cluster Malfunction - When Starting Speedometer Needle Go Crazy
I am having a slight issue with my cluster. When I turn the key on or start the car, the speedo needle goes crazy for about a minute then stops above 0mph (points at 5mph when im not moving). While that's happening, the other needles don't work until the speedo normalizes. It also does this when i turn the car off. What this could be? I heard about the VSS can cause speedo issues but what about the rest? I also heard the mk4's can have cluster failures. it's a 99' mk4 vr6 jetta 5spd.
View 3 RepliesDiesel - Jetta - Volkswagen :: Cannot Go Past 30 Or 40 MPH Up The Hill
I have had power problems with my Jetta when driving into the mountains for the last 2 years. The first major repair I had done 2 years ago was to fix a fuel leak in the fuel injection pump. It seemed great driving around town for about six months. I took it to the shop again and this time they said the intake manifold needed to be cleaned. After that it seemed fine for another few months- then not. I took it in this time to the Volkswagon dealership. They found a hose that had a bad tear. That fixed the problem until I discovered a couple of weeks ago that once again I cannot go past 30 or 40 MPH up the hill.

I have the above referenced car with about 65k miles on it. Today I took it for a drive, switched it to tip-tronic manual and found that the car would not shift past 3rd gear. When I switched to automatic, the transmission stayed on tip-tronic (the display indicated I was on 3rd gear). I had to fully stop the car, place it on park and only then did the transmission switch to automatic.
View 1 RepliesGolf VI R :: Does Vehicle Rev Past 5K When At A Standstill In Neutral?
Does your Golf R Rev past 5K when at a standstill in Neutral? I just finished installing the New South performance Gauge. I routed the boost line hose through the firewall. I used the supplied T fitting and replaced the stock one. I hooked everything up but the power for the boost gauge, just testing and checking everything before I proceed.
I put back on the battery without replacing the battery clamp at the bottom. But I connect and tighten the terminals. I am testing it now to see if all is functioning as it should. I start up the car, and I the vac sucks down to -10 PSI as I expect it.
Then I give it a rev to see if it will build boost. Almost immediately I notice a problem. Seems that the engine wont rev past 4-5K.
So I think, okay, well I probably didn't tighten it down properly, and I have a boost leak. So I pull off the engine cover, and put back on the stock hose. clamp it down, put back on the engine cover, and start the engine again.. The same thing... wont rev past 4-5
I look on the dash and two things pop up. one, the check tire light, and two the tires slipping light is solid. (I thought that VW didn't have active TPS sensors in the these cars anymore, but instead are using wheel rotation to calculate air pressure loss, if this is the case, then why would the check tires light just turn on when it wasn't moved. Could the fact that I disconnected the battery cause an issue? with this?)
I am still thinking boost leak. So I get some soapy water and spray around the only hose that I took off on all the joints, I put back the cover and connect the MAF again. then I start the engine, I figure a few revs will build enough boost to show any leaks in that area with bubbles. But no bubbles...
So now I am wondering if VW put a safety that prevents the engine from revving past 5k when in neutral. I would rather not move the car, until I know for sure that there is nothing wrong.
Golf/GTI VI :: Slight Vibrations In The Seat And Steering Wheel Past 60 Mph?
Experiencing slight vibrations in the seat, and steering wheel past 60 mph on the stock wheel & tire set up? I've got about 10k miles on my Pirellis and am thinking that all the winter driving (potholes) have knocked them out of balance. The VW dealer claims they balance fine, but I can feel the vibrations. Just wondering how everyone else is liking their stock set up.. Maybe a wheel has a slight bend? Nothing I can notice from a quick glance tho.
View 6 RepliesGolf IV R32 :: Blinking Engine Check Light When Go Past 2500 - 3000 RPMs
I've been getting a blinking engine check light.. I pulled all the codes:
P0050: H02S Bank 2 Sen 1 Heater Circuit
P0155: O2 Sensor Heater Circuit Malfunction Bank 2 Sen 1
P0304: cylinder 4 Misfire detected
P0688: ECM/PCM Power relay sensor circuit
I've had the car sitting for awhile because I lost my job and didn't have any money to roll it around much.
I just changed out the spark plugs and two of these had a white coating on them.. I was hoping this would take care of the misfire after I replaced them. I also bought a new battery because mine had lost charge a few times.
The Car will run with an engine check light, but if I go past 2500-3000 rpms then it will start blinking (which means don't drive it )
The oil has been sitting in it for about 2 months, so I'm about to go change that and I'm hoping this will allow me to drive it without issues.
Any of these codes thrown and know what they could be? Which O2 sensor (like a link to a website that sells them). Trying to get this thing running again.
