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 Replies03 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.
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.
View 8 RepliesI 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.
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
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?
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?
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.
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..

View 2 RepliesI 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). Eventually, they got an error code of P0730, which I believe is electrical-related. All was pretty good but then today, driving @ high speed on the interstate, I could not get into 4th gear...
View 1 RepliesI have a 2008 F350 with a 6.4 Powerstroke diesel engine that just experienced total engine failure. It has around 65K miles.
There is a heavy burn star pattern on all 8 pistons, a few pistons are cracked, a few cylinder walls are scored, glow plugs are melted, both heads are cracked with multiple stress fractures in each head.
About 1 month previously, the transmission would not work in tow mode and caused the engine to go into limp home mode. The dealership just replaced the entire tranny as a warranty item. About 1 week before the engine failure, I put in a 5.25 oz bottle of Lucas injector cleaner with a full tank of gas.
The Ford dealership is saying that the star pattern on all 8 pistons is due to high pressure fuel overspray and is evidence that I had a tuner on this engine and that the warranty is invalid. I did not have a tuner. What might have caused this engine failure?
Also, they only ripped down the top half of the motor, not the bottom half. I heard this might have been caused by a cracked crank shaft, but Ford refuses to investigate this possibility.
Twice now, my 2006 VW Jetta has gone into "limp mode"--RPMs rev like mad but I get very little power, won't go into overdrive. Had to get it home both times by using the Tiptronic. The first time it happened, we were driving through The Poconos on a nice day. Shut the car off & restarted it with no problem. The 2nd time was during an intensely hot day & torrential rainstorm in MD. The car sat for 2 days before going back to normal. Is this normal behavior for a VW? And what makes it go into limp mode? I can understand it happening during the rainstorm but on a nice day of normal driving?
View 1 RepliesI have been having trouble with the shift solenoid and the trans going into limp mode. I recently replaced the shift solenoid and I now have the same problem but just when the temp outside is above 90 F or when I sit in traffic or idle for more than 3 or 4 minutes. The same code p0758 comes back up. I was thinking maybe the temp sensor?
View 2 RepliesMy tranny is stuck in limp mode. I can manually shift it, but it won't shift on it's own. The 'automatic' part of the automatic transimission is definitely not working right.
I searched and checked for the usual suspects, low battery or alternator output (measured over 14v at batt. when on), and the range selector switch. I removed the switch, took it apart, cleaned it up, and reinstalled it. It looked like it was in decent shape inside, although it appeared to have had a bit of oil of some sort that had leaked into it. There was a bit of oil on that side of the tranny, around the gear selector and switch, but not enough to actually drip as I don't have any stains on my driveway where I always park. The only thing I haven't checked is the atf fluid level, as I can't seem to find the my wrench that will take off the fill nut. I'll get that figured out tonight.
The tranny hasn't been taken care of like it should, I've had the fluid replaced two or three times over 100k of ownership, but I'm not sure about the filter. Would the need for a filter and fluid change cause it to go into limp mode? Also, it's not throwing any CEL codes either.
33K and no problems until this morning. Wife gets 400 yards down the street, car "lurches" and goes into limp mode. Transmission won't shift out of whatever gear its stuck in (going forward) Car will back up. Only indication of any possible trouble is occasionally the very first time the transmission shifts in the morning from 1st into 2nd its a little spirited rather than silky smooth.
View 5 RepliesMy transmission control module has gone bad, resulting in the car being in"limp" mode. I am advised not to drive the car in this condition as it starts out in 3rd and the transmission will be damaged. Thus far, my local dealer has, on a preliminary basis, been advised that there are none of these parts available anywhere in the world according to the computer and VW may have to manufacture one. This does not sound possible. Meanwhile, the dealer says no rental car will be offered so I am contacting VW North America to escalate. It could be up to a month to get a new part. Meanwhile, the car is in the garage just sitting.
View 7 RepliesSo yesterday, this had happened for the third time in 3 years owning this car. Unhooking the battery for 20-30 minutes resets the computer and it is ready to go for a while with no issues. This has become annoying though. What is causing the car to enter "limp" mode and stay in third gear? One time it happened, I brought it to AutoZone and they did a scan and came up with the speed sensor. I haven't replaced it because it didn't happen for a while after that.
View 11 RepliesTurn air conditioner on transmission goes into limp mode??
1999 ranger 2 door 2,5 engine long wheel base,,auto trans.
2wd no power windows no power seats....
I'm a little bit stuck here. This happened last night, and the dealer is closed today. I have a 2008 Santa Fe SE. It stalled last night, and when I turned it back on, I got a check engine light, the ESC light, and the AWD transmission light blinking. When I go to accelerate, it will not go passed 2000 RPM, and it is driving very sluggish. Its not knocking, or making any other kind of sounds. The air conditioning does not work, but the fan blows uncooled air. It accelerates extremely slowly, even with the petal mashed.
I plan on taking it in tomorrow, but I'd like to know if there is some way to reset the computer. I tried disconnecting the battery for about 30 minutes, but it didn't work.
I have a 1992 1500K extended cab 4WD with the 5.7L V8 engine (147,000 miles). It has been driving well since I bought it last winter. 2 days ago I took it on a longer road trip and it was doing great. Slowed down to take a 90 degree turn and the transmission suddenly hit "limp home" mode. It felt like it wasn't up-shifting out of 2nd , high RPMs while driving no more than 30mph on flat road. I have the proper amount of fluid and it is still red/pink and does not smell burnt.
Someone suggested that I check the transmission fuse but in looking through the fuse box I can't tell which is the tranny fuse. Also, I can only find one fuse box on my truck. Is there a 2nd?I feel like my next step is to take it to a transmission shop but I want to rule out whatever I can at home. I have zero experience with transmission work and don't want to get scammed into a rebuild if I don't need one. The transmission was working fine up until 2 days ago. No slipping, no hard shifting, and no noise...
