Passat (B6) :: EPC Light Came On - Engine Went To Limp Mode
Jan 28, 2012
Passat 2008/09 TSI engine 16k miles. APR stage 2+
I was driving normally and suddenly EPC light comes on, and the engine goes to limp mode. I turn the engine off and then turn on again. Everything runs fine. Vag shows N276 intermittent fail. I had already this fail, but always when starting engine, and the engine used to run OK. Is this a "sign" that is time to replace the HPFP? Or can I take the chance and keep running?

My friends has an 06 3.6 motion sedan and has a problem. His car went into limp mode with the ECM and traction control light as well as CEL. we took it to the local dealer (45 min away) they scanned it and said that the throttle pedal was the only code that wouldn't clear. He ordered a new pedal from ECS and installed it today. The cars still in limp mode we read about a potential throttle body adjustment procedure (not too sure of the validity) any how followed it open hood open door ignition in the "on" position for a few minutes. After that when he started it every warning light came on. Is there a step in pedal replacement we re missing? On a side note the connector on the pedal end was fairly damaged not sure what from maybe the po had a botched replacement attempt? Not too sure what to try next.

Truck: 2009 F-150 Lariat SCrew 5.4 4x4 with 6.5" bed
For the last few years, I've had this intermittent problem where the service engine light (wrench icon) will pop on and the truck will go into limp home mode. While it's in this mode, all of the indicators on the dash freak out. Low fuel warning will come on, temperature warning, low battery voltage, etc. Turning the truck off and back on (sometimes a couple times) is enough to get it back to normal, albeit with a check engine light that needs to be cleared. It's happened infrequent enough that I've just been dealing with it. I got the codes a couple years back, but there wasn't much information available on what the potential causes might be. The Checker Auto parts database suggested one might be related to a wheel speed sensor.
Well, this afternoon it happened again, and I was near an O'Reilly, so I took it in to pull the codes. There were 9 total in the system; 5 of which were unique:
B0025
B00D5
U0073
U0100
U0253
They didn't have any information on what was causing them. What could be causing this. I'm getting sick of having to clear the check engine light and worry about the truck falling into limp home mode when I'm at intersections.

The transmission has started going into limp mode and causing the check engine light to come on.
The codes given are p0750 and.... I think p0751, for shift solenoids C and D. There is also the generic Transmission Control Module code.
Limp mode only occurs at higher speeds although shifting feels a little rough at times in lower speeds.
If operated in manual mode the vehicle can be driven normally at all speeds without going into limp mode.
Fluid levels are fine.
With limp mode occurring in automatic but not occurring in manual mode, is it more reasonable to believe the solenoids are malfunctioning or the control module itself? I'm inclined to replace the solenoids but find it odd that the vehicle operates normally in manual. Also, can the solenoids be replaced without removing the transmission? It looks like I could get the pan off but am unsure if there is room to get the work done once it is removed.

I 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.

Bought a brand new F250 6.7 it has 7000 miles in it now and the check engine light comes on and the truck goes into limp mode. I have taken it in to the dealership twice they said there is no code they can find and they just reset the check engine light and it does ok for a bit then starts the cycle all over again. It also is only getting about 6.5 mpg....

Replaced HPFP 38,000 miles ago. Truck began going in limp mode without engine light, wrench came on in dash, gave codes for brake switch, anti-theft, some other weird codes. Had those codes cleared, ran for while then water separator came on, drained the water out, came back on. Read some forums, so I removed and cleaned the housing, cleaned off the sensor. Had code cleared and ran good for about a week. Then guess what engine light comes on, limp mode.
Went to Auto Zone, pulled code P0088. This truck runs awesome until limp mode. No other problems. I take it to the ford dealer, scanner pulled P0088 and the water separator code again. I have read alot of remarks about this P0088 code. Can there be another cause for pulling this code, only 38,000 miles later. I had them do the TSB 12-07-07 but I have also read it can only be done if the P0088 is the only code. I just really feel there is an underlying issue with these 6.4's.

so i was driving the vw and the car starts surging like its in limp mode but no cel! so i stopped and checked my engine bay to see if maybe my intercooler piping came loose but nothing! so i shut it off for about 5 seconds and turned it back on and it threw a cel! the whole time i was driving it home felt like it was going in and out of limp mode and would not boost past 4 psi! check the cel and came back as this:
P0238 turbo/supercharger boost sensor a ckt high input
p0106 map/baro ckt rng perform

I have the problem of over boosting and hitting limp mode. now does that mean i adjusted the actuator wrong when putting it back on? if so how do i adjust it properly. or is there something else i can do to make the car come out of limp mode? also since it is boosting past a certain psi should i put a mbc on it and adjust it down?

Wife's Passat went into "limp mode" and will only give me 4th gear. Check engine light came on when it happened. I had a buddy scan the car with OBD scanner and it is saying Sensor A is bad? Which sensor this is, or thought of writing down the code that it was throwing. My guess is the speed sensor for the transmission.
Luckily the car is a W8 and has enough power to pull the car from stop in 4th gear. There aren't any reputable VW dealerships in my town or any neighboring town. I've decided to take the car to a VW/Audi specialist some 60 miles away. They told me they can take a look and replace if needed. I absolutely do not trust VW dealerships/service around here. I've heard nothing but nightmare stories about them.

I have a 2004 1.8T AWM auto tranny Passat with APR chip. CIA, Bolt down Coil Packs, Bosch F6DTC plugs, OEM cat to straight pipe to magnaflow muffler, N75J, Forge DV (not the 007).
I installed a MBC bypassing the N75 to keep the spike at 16psi and hold (the n75J i spike at 22psi and hold 12~14), When I did that, the car will go in limp mode from 'over boosting'. I have to turn the MBC down to 9 to keep the car limping out. I love the way the MBC have the boost curve (the N75 is too passive for me). would like to fix this issue.
Also, with the N75 and or MBC, while in the APR 93 oct chip mode, I always get surging in 4th and 5th gear. Any time the boost is over 10psi, it is like I have tons of boost, but the engine is not using it. APR said it is the tranny, the tranny shop said it is the engine or computer, the engine shop said it is the tuning.

I got into my car about 5 minutes ago and while driving i noticed a ample amount of power loss. I would go half throttle and my rmp's would go up by my speed seemed lacking even full on it it seemed to be lagging and was a slow climb to 60. Could it be my turbo not putting out or something more serious. Its a 99 1.8t ....

We have a 2006 Passat, 30K miles, live in northeast on a Great Lake. We bought it used in 5/07 with 11K miles on it. The other day, a whole mess of warning lights came on, and the car went into "limp mode." The dealership diagnosed corroded wires where they connect to the throttle valve controller. We usually keep our cars for years, and we've never had corroded wires before. Is this a typical problem of VW's? The service mgr said he'd seen about 6 come in in the last year, but I don't know if that's a lot or a few compared to other brands. We're getting ready to shop for cars again, and we'd consider a new Jetta, but not if it can't go out in the rain. Also, if the wires corroded once, what will keep them from corroding again? Should we expect this to keep happening?

So on cold mornings my r has been kicking on the epc light and gone to limp mode. The only codes are for the coolant temp sensor and an intermittent accelerator position sensor. Would the temp sensor really cause this? After awhile I can start it up and it runs fine.

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?

So this morning I was driving to work - normal driving no hard accelerations. As I stopped at a trafic light the car felt going into a limp mode? - engine started to misfire - no smoke from exhaust - but felt is was going to stall. Also the idle started fluctuate from low 600 to high 1100. At low RPMs the engine felt stalling but when I drove around 3000 RPM in 4, 5th gear felt fine.
I was able to plug in the APR dongle and got 7 fault codes: 1)DTC Not Found, 2) Idle Air Control System RPM HIgher than Expected; 3) Random/Multiple Cylinder Misfire Detected and 4,5,6 and 7) Cylinder 1,3,4,2 Misfire Detected.
I am APR 1+ with VWR CAI, 20K on 93 oct.
Coil? Injector? Manifold? HPFP?

Just set off on a day out, got about 3 miles and the cars gone into limp mode (running smoothly but no power) with the glow plug light flashing. I got back to the caravan so we weren't stuck at the side of the road and tried restarting it. It starts off for about a minute before coming back on. I've noticed that revving it in neutral the revs linger for a second our so after taking my foot off as if its not recognizing that the throttle position has changed.

Just to save you all some time.... If your car goes into limp mode, and/or cruise stops working, and the EPC light comes on..... We had over a week of downtime and hundreds of $ out to find out that the literally brake light switch broke - its apparently flimsy and triggers all kinds of electrical faults..

2001 Ranger 3.0 liter has developed a transmission casualty. I was driving along at 30 mph and the transmission went into "limp' mode with O/D light flashing and truck will only barely creep along with high engine rpm. When I got the truck home I was able to retrieve a p0720, output shaft speed sensor signal fault. I had hoped that replacing the sensor would solve this casualty.
Of course this was not the case. I have read all the posts I can find for this particular fault and realize that I must electrically trace the continuity of this circuit and also ensure that it's not grounded. I have been unable to find the needed wiring diagrams or pin out information.
Before I have to try and blindly start pawing through the connectors I'm looking for the pinout for the PCM and perhaps the bulk connector above the engine between the PCM and the transmission wiring harness. I am also keen to hear of any diagnostic tips that I may have overlooked.

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..
