Golf IV / Jetta IV :: 2000 - Backfire During Downshift
2000 2.0 has full oem exhaust, when downshifting it pops, could this be something in the exhaust or fuel? Not sure as it pops about 2-3 times per downshift. No more no less.

Preliminary info:
APR 93 tune
Carbonio Intake
Silicone TIP
I picked up my 20th today and drove it 4 hours home. It has 74k on it, original timing belt. The timing belt kit is in the mail on its way here. Its the first thing I'm doing.
As I was driving it home on the autobahn doing about 150k/hr and I gave it half throttle to pass, I felt the turbo spool and I accelerated past the car. However, when I went to make the next pass, it felt like I had no power. I feathered the throttle a bit and it felt like my car was only getting maybe 3 PSI of boost. Very little actually. I do not have a boost gauge so I can't really say it accurately. As I was driving, i shut the ignition off and turned it back on. After that, I was able to get full pressure back.
Golf IV / Jetta IV :: Idle And Backfire - No Power And Stuttering
1.6 FSI .. Very long story short, the engine is running like crap, idle is jumping up and down. Almost no power, its stuttering and so on and so on. Well I talked to a mechanic and he found out the problem, a throttle vacuum. (kinda like choke) he explained it as.
The part was ordered, and arrived. Me and my dad tried changing it and we met some struggles. After looking at it closely and trying different things we kinda gave up.
Here is the part that is broken, it adjusts the amount of fuel when its cold vs. hot
We concluded we needed to take the whole intake to access it ?
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 :: Soft Shifting Into 2nd / 4th And 6th Gear
When I was driving on Friday I noticed that moving into 2nd, 4th, and 6th were "soft." I could hardly feel it engage into those gears at all so I thought maybe I would adjust my linkages. So I adjusted my linkages and while sitting in my drive way everything felt solid. When I took my car for a ride down the street I could feel it engage 1st, 2nd, 3rd no problem but after driving around for a few minutes my 2nd, 4th, and 6th gears felt soft again and then it got worse where I couldn't even shift into those gears anymore.
So my R, 1, 3, 5 all worked fine but didn't have 2, 4, 6. After taking a look at my linkages and I pulled off the selector cable and and shifter cable end. I noticed that on the shifter cable end that it felt wobbly and on the selector cable end it was rock solid. I am just wondering if the shifter cable end being worn out could be my issue? Is the shifter cable end supposed to have a little play in it and be wobbly? Or is there another issue I should be looking for? Here is a video of just how wobbly it is. [URL].....
Golf IV / Jetta IV :: Transmission Going Into Limp Mode
My Jetta mkiv transmission went into limp mode recently. Took it into shop. They checked it out and they replaced solenoids as well as the TCU. Car still goes into limp mode. It doesn't happen all the time but enough to piss me off. Any thoughts?? Car only has 140000 miles.
View 1 RepliesGolf IV / Jetta IV :: 2003 Goes Into Limp Mode With AC On?
03 manual goes into limp mode with ac on like turbo has no power and wont go past 65. No engine light comes on though. Does engine light have to come on to go into limp mode??
I don't have Vag Com. But i'm familiar with diesels. Maybe something is losing vacuum when a/c comes on because i know the ducts and all that work off vacuum in most cars. Does the ducts for TDi work off vacuum also??? Maybe not enough vacuum going to VNT activator?? I'm clueless with these cars.
Golf IV / Jetta IV :: 2001 - Loud Backfire - Replaced Chain Guide Still Rattling - Only 3 Cylinders Working?
So, I was driving down the road one day at like 50mph or so and had the loudest backfire I've ever heard. As I was putting my car on the dolly to tow home I heard a bunch of rattling and thought maybe it was a rod bearing or something. I pulled the oil pan and found chunks of my upper chain guide (rod bearings were fine).
I replaced the chain guide and checked the timing hoping it would fix the problem, but it didn't. The rattling was gone but I was only running on 3 cylinders. Did a compression check and had 0 compression in Cyl5 and about 60-70 in Cyl2. I don't remember exactly what the compression was for the other cylinders since it was a while ago.
Started thinking it was bent valves, so I just recently pulled the head off to check them. They all looked like they were seating properly and none looked bent from what I could tell. I'm about to try to put some compressed air through it to see if the valves are leaking anywhere. the plugs, wires, and coilpack are all functioning properly.
Golf IV / Jetta IV :: Clutch Pedal Feels Soft Since Replacement - No Air Coming Out
I changed my oem clutch in my mk4 golf 2.0l with a stage 1 ecs tuning clutch kit. Lightweight flywheel, clutch disk, pressure plate and throw out bearing. But since I have my clutch pedal has been less stiff then usual. I like my clutch pedal as stiff as possible but it just isn't I bled off the slave cylinder. When I was done no air was coming out but it is still way to soft for me. What should I do next??

New to the jetta (used to own Saabs so not new to issues) OK, 2003 jetta 2.0 CEL is on for the CAM Post sensor. Car is in limp mode. has been for a while before I touched the car. I have replaced the Cam post sensor, I replaced the Crank Post sensor, replaced the coil pack, replaced the water pump and the timing belt. I have searched a lot of the other threads before posting this one. Triple checked the timing (3 people did not just me) I replace all the other stuff because I had codes the water pump and the timing belt just because they were due. i had one last code P0343 so when i replaced the WP and the TB i replaced the sensor. Still in limp mode, still have the code i pulled the plug on the Cam post sensor. then i said to my self this car should NOT start. but it did start and i drove it around a little, shut it down and car started up again so I am at a complete loss.

I have a 02 Jetta TDI, I have had the car
For about 8mo, and have been fighting a random limp mode problem the whole time.
I have gone thru and changed the common issues, N75, MAF, actuator on the turbo, and changed all the vacuum lines, fuel filter..... Etc. I'm to the point I want to light the car on fire, and see if the engine light goes off!!! Is there something that I have overlooked.
Golf IV / Jetta IV :: When MAF Is Plugged In, Boost Cuts Out And Goes Into Limp Mode
I currently own a 2001 Jetta 1.8t. It is currently tuned for 15 psi supposedly. I have never seen that number been hit and the highest it will go(only in 4th and 5th gear) is 13-14psi on a good day. And even when it does get there it does not hold the boost what so ever. It will start losing boost almost as soon as it reaches those numbers. Another thing is my MAF is currently unplugged and is making my car throw a code. When MAF is plugged in it cuts out boost and goes into "limp" mode.
Here are some engine mods that may be apart of this issue:
- Front mount intercooler, full intercooler pipe kit
- Oem diverter valve
- N75 j valve
- ACHTUNING tune on 15 psi not sure which stage
- Forged turbo inlet pipe
- 032 motorsports crankcase breather hose conversion
- Ecs tuning
- 2.0t coilpacks and mounting plate
- AWP head
Golf IV / Jetta IV :: ASR Light Permanently On / ECP Turns On And Car Goes Into Limp Mode
2001 Jetta 1.8T wolfsburg
When I start my car the ASR light is already on and I cannot turn it off by hitting the button. It's just permanently on. Then as I start to drive and step on the throttle and get above 3000rpm the ECP light turns on and my car goes into "limp mode". Then in idle the engine stutters and RPMs go up and down, up and down. I'll turn off the car and the ECP light disappears but comes right back on again after getting above 3000rpm.
Thing is, these issues only appeared immediately after the following:
-Disconnected and reconnected CCM (checking for faulty wiring, battery was connected during this)
-Disconnected battery terminals for 3 minutes and reconnected them (no key in ignition)
Did I cause an issue by disconnecting battery?
Golf IV / Jetta IV :: 2002 - Flickering Warning Lights And Limp Mode?
I have an automatic (ugh) 2002 Jetta 1.8T that is displaying some fun stuff. My kneejerk reaction is that the ECU is croaking but wanted to run it by some people with more experience/smarts.
Here's the deal. I don't get any codes, ever. Sometimes, when I turn the ignition to on (Before starting) all of my warning lights are dim and will flicker, and the gear indicator at the bottom of the cluster rapidly switches between each gear. If I start the car like this, I can hear the shift lock randomly engaging and disengaging. If I actually try to drive, it'll shift hard into reverse, shift normally into drive, and then drive in limp mode. I only drove this way three times before figuring out the next bit. Each time, either the traction control or air bag warning lights came on and stayed on.
I've noticed that if I turn the ignition to "on" and it's acting up, all I have to do is leave it on for a few seconds, turn the ignition back off, and turn it back on; sometimes it'll take 2-3 tries but it always seems to work. Then the warning lights come on bright and steady, the car starts like normal, and drives great.
So, is it the ECU? Is it demons?
Golf IV / Jetta IV :: Rolling Start / Limp Mode / Dim Dash Lights And About 300 - 400 RPM
I have a Mk4 1.8t , I left a light on and near killed the battery one night , was parked on a hill so I let it roll start.( I know this is where I went wrong so lets get past it....) It started in what sounds like some type of limp mode, dim dash lights and about 300-400rpm. cruised at about 10mph for say a 1/4 mile before the engine returned to normal rpm and lights returned to proper brightness.. now the car has a problem I cant seem to put my finger on. When it gets to about 3000rpms it bucks and begins to throw multi misfire codes making it hard to even get to 30mph.
It reminds me of how it felt when all the coils started failing but I know it cant be that because its all new , (plugs ,coils,) I have also replaced a few other easy parts such as the n75 and the diversion valve next to it, as well as the fuel pump and filter. One thing I noticed when I leave my n75 unplugged (wide open) it seems to run better making it easier to drive but if I go anywhere past 1/4 throttle it bucks and struggles. I've used the Autel to scan it for other codes but the only thing I get is random multi mis codes and mis codes for each individual cylinder.
Golf IV / Jetta IV :: Brake Light Flashes 3 Times Then Stay On / GLI Will Go To Limp Mode
I have a 03 GLI 24V VR6 6 speed and im having an issue with the brake light.. ive checked all the fuses and emergency brake sensor and they are all good, the issue is the brake light flashes 3 times then will stay on almost immediately and whenever it does the entire drive of the car changes.. without the light on the car runs fine but when it comes on its like the car goes to a limp mode and is leaning out on fuel.. it wont rev past 4k it falls on its face and basically jerks along until I get where I am going.. I've replaced ABS speed sensors, MAF, and front brakes and axles recently.. before this was an random issue that would come and go but now its almost every time and it makes it undriveable..

I have 1 month left on my AAMCO rebuilt transmission. I took it in a few weeks ago when it went into "limp mode" (Stuck in 1st gear).

View 1 RepliesMazda - Transmissions - Mazda6 :: 2005 - Soft Scratching Noise When Accelerating
I have had this car for 4 years, and it's been driving, and handling very well overall. Lately, I started hearing a soft scratching noise when accelerating, and especially going from 1st to 2nd, and 2nd to 3rd gear. There was some hesitation before shifting to the higher gear as well. I took the car to a local mechanic, and after test driving, and listening to the engine with a tube??? he told me that he needed to change the torque converter and the pump, and quoted me for $1936. My wife immediately wanted to sell the car and buy a new one. Half of my friends said the same thing (well, at least my richer friends did), and the others said to fix it and drive it while I could do so.
So, I took the car to another transmission specialist, and they told me that the transmission was in great condition, fluids, shifting, etc. Something doesn't add up here. I know that the engine/transmission doesn't sound the same as when I bought the car, but how is it possible to have that kind of diametrically opposite diagnosis. Meanwhile, I took the Mazda to a local dealership, and they quoted me for $4500 trade-in value, while CARMAX said they would give me $2500. Needless to say, I am at a crossroad - we know we have to change the car soon, but how soon and under what circumstances, this is the question. Then, just today, another mechanic said that the engine is unbalanced, and is giving a low, and powerful vibration, and the harmonic balancer needed to be changed.
