Passat (B6) :: Parking Brake Fault Light Came On, Car Went Into Limp Home


Mar 14, 2011

Today the roads were slushy. On my drive to work a strange parking brake fault happened twice. Each time I was driving at highway speeds, not engaging the parking brake. In each case, the parking brake fault light came on, and the car seemed to go into some kind of "limp home" mode: the car would not accelerate or upshift, although it appeared to be willing to maintain around 40mph or very mildly accelerate from 0-20 mph if I stopped all the way. This was not because the parking brake engaged itself and was slowing the car - the car still coasted freely. It was clearly because the computer was limiting the car's power/speed severely. In the first case, I think it came on when I was beginning to apply the regular brakes to slow down gradually for a light; and in the second I was not using the brakes at all but did hit a puddle of slush. In both cases, it's possible the traction control kicked in, although I did not see that indicator light flash. The ABS did not get used based on sound and pedal feel in the first place, and because I wasn't engaging the brakes at all in the second case.

In each case, I was able to pull off the road, shut off the engine/car entirely, and then restart the car to clear the fault and turn off the light. The car drove totally normally from there, as if nothing had ever been wrong. There was around two hours including 90 minutes of being parked in my garage between the two events. I've never had any parking brake malfunction of any kind before with this car. So now I'm wondering when this will happen again. This does not appear to be the common problem of the parking brake button, since it never involved actually applying or releasing the parking brake and never involved me touching the button. I don't like having to quickly go from the left lane of a freeway all the way to the right lane or shoulder when my car suddenly decides to slow down for no obvious reason.

Passat (B6) :: Got Message - Parking Brake Fault?

I bought a new battery tonight at my local VW dealership and after replacing it in the parking lot I got into my car, started it up, and saw 'Parking Brake Fault - See Owners Manual'. Seeing as I dont have an owners manual as when I bought it used, it didn't come with one - The car is still driveable but does not shift out of gear and when I go to engage (automatic) Drive, Reverse, or Sport, from the Parked position it makes a hard clunk and small jerk before it engages. The MFD is as if I am still parked because I can access all the comfort sections, and all transmission selections are highlighted. Im not sure if it was in Neutral or Park when I engaged the Parking Brake before I changed the battery so maybe and Im hoping when I took the old battery out, and put the new one in, that something wasnt set correctly when the car started up after having no battery power???

I am curious to know what possible ways I can rectify this. Its sitting in the VW dealership parking lot and Im hoping they will be able to take a look at at it in the morning but of course I wanted to check here. Also, what does it say in the Owners Manual about a Parking Brake Fault?

Passat (B6) :: 2006 - Electronic Parking Brake Fault

I went skiiing this past weekend in Angel Fire, NM. When it was time to leave on Sunday I started the car and proceeded to undo the parking brake (I was parked on a n incline). As I press the button I get a message saying something like "Electronic Parking Brake Fault. Please Service". Then I press it again and it works. Is this something I can expect more of, or could it be due to the cold weather? It was 13F outside then at the time, and the car is a 2006 with 52K on it.

Passat (B6) :: Parking Brake Fault Causing No-start?

Happened to me twice today, engine wouldn't start, message on MFD was "Parking Brake Fault" and the engine would not start. I read through he owners manual looking for a solution, and the engine finally restarted and I was off on my merry way.

About two hours later, on another errand, this time I started down the road, the engine died, I tried a re-start, got the same "Parking Brake Fault" message and this time the engine would not start. Tow truck is going after the car right now. This leaves me a bit frustrated why a parking brake issue would kill the engine.

Passat (B6) :: Parking Brake Fault As Soon As Turn On The Ignition When Car Is Cold

Its been consistently below freezing around here and when the car is cold, I get a parking brake fault as soon as I turn on the ignition. When I press the button it will usually release the brake, however further presses result is flaky operation, inconsistently flipping between working properly and showing a fault. However, if I can clear the fault, Auto-Hold works fine, and once the car is warmed up, the parking brake works flawlessly.

Passat (B6) :: Engine Revs Up For A Couple Of Seconds Then Parking Brake Fault

I have a 07 Passat, manual 2.0T, 90 kmiles.

There was a recall for some faulty circuit in the steering column, which got replaced in September. Ever since the replacement, about once a week (with a daily commute of 40 miles each way, mostly congested highway), the following happens:

First the engine revs up for a couple of seconds when I change gears, to 4-5kRPM. Then within 5 minutes, I get a "Parking Brake Fault" message, together with the yellow P light staying on. If I stop the engine, I cannot restart it for 30 minutes or so, there's a message that says "depress clutch first".

When I finally manage to restart, I won't have a problem for about a week. Is this common?

Ford F-150 (2009-2014) :: Check Engine Light And Limp Home Mode

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.

Nissan - Sentra :: No Power When Given Gas / Car Now Stuck In Limp Home Mode

A few months ago, my '00 Sentra developed a rough idle but I ignored it because it wasn't too bad, until recently at least. It had been getting progressively worse so I went out and bought some CRC MAF cleaner, which solved the rough idle altogether for about a day. After doing some errands, I started the car but it was now stuck in limp home mode, not matter how much gas I gave it, she wouldn't top 20 MPH and 2.5k revs.

I bought a new MAF, and that made the problem worse: in any drive gears or reverse, when given any gas, the engine would stall and die but when in neutral, I can rev it as high as I want to. I reset the computer and cleaned the new sensor to no avail. After re-installing the old sensor (which was visibly broken, it was missing an entire wire assembly), it will run poorly but will now drive with some quirks, and I don't trust it further than around the block.

My question is: with the new sensor, do I need an ECU reprogram, did I receive a bad sensor, or is there a compound problem? (I've heard with similar issues: bad alternator, bad TPS, bad IAC module, dirty IAC or TPS, clogged fuel filter, bad fuel pump, dirty air filter, among others.)

Phaeton :: 2004 - Adaptive Cruise Control Causes Limp Home Mode

I am one of the few that has ADC on my 2004 V10.

Occasionally, 3 times now. I press the ON button and the cruise control does not initialize properly. After a while it will say "Temporarily unavailable" . The problem is that then there is no power any more.

I stop on the hard shoulder of the motorway, engine off, engine on and all is reset, ADC works ok and full power is restored.

Chevrolet - 1500 :: 1992 - Transmission Suddenly Hit Limp Home Mode

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...

Passat (B5) :: Rear Parking Light Went Out, But Brake Light Works

Recently purchased a 2001.5 Passat, and of course got the mod itch... started with an Neuspeed ECU flash & DV, along with K&N... and now I'm in the process of suspension & exhaust... Unfortunately the past week, I was told that I had a tail light out.... Upper Rear Passenger Side Parking/Brake Light.... So I figure, hit up the parts store, grab a new bulb, and I'll be set...

Well, come to find out that it's not the bulb....

The light works when I brake, so 1/2 of the bulb is good... but the parking lights won't come on that side, but on the driver side everything is good..... even with the new bulbs..(replaced both on that side[passenger] just to be sure.)

So, just out of curiosity, I took one of the old bulbs that I thought was shot, and put it in the drivers side, and what do you know... it worked flawlessly on that side...

So, I'm led to believe I have a short... or a wiring problem somewhere... but I can't see how this could have just happened without really messing with anything... I mean, I disabled the DRL's.... but I even undid that(small piece of tape covering the B prong)... just to make sure..

Passat (B6) :: Dinging Sound While Driving - Parking Brake Light On Dash Keeps Blinking

So I washed the car today, and when I was done I had the Parking Brake error. Now the button keeps blinking and the parking brake light on the dash keeps blinking too. I don't think the brake is actually engaged, but I am afraid of pushing the button now in case it locks up in "engaged mode". That way I can't drive to work tomorrow. I know this may just be the button, but driving around with this dinging sound and blinking lights is annoying.

Honda - Accord :: 1998 - Parking Brake Light Comes On Until Jiggling The Brake Handle

The red dash light for my parking brake stays on until I jiggle the brake handle, then it stays off until I re-start the car the next time and then it goes on again. Brake fluid is fine.

Appears to be a faulty switch attached to the handle. How do I fix this? Is it a major job? [it's a 1998 Honda Accord]

Passat (B6) :: EPC Light Came On - Engine Went To Limp Mode

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?

Ford 7.3L Power Stroke (1999-2003) :: Parking Brake Light Doesn't On - Replace Brake Sensor?

I just had a remote start installed with a turbo timer that works off of the parking brake being engaged. No matter how hard I press it the light does not go on, however when the installer probed the sensor to ground it, it worked fine.What part this is that needs to be replaced. The stealership quoted me at 200 something for a whole parking brake assembly.

Touareg :: When Parking Brake Released In MFI Got Warning Parking Brake Fail To Release

Had my car parked outside of work for about 12 hours yesterday, and in the NYC cold front, the parking break must have stuck on slightly. When I started to move, despite the fact I'd released the parking break, I received a warning in the MFI that said PARKING BREAK FAILURE TO RELEASE. I pulled the handle again and heard it pop just a little more off. Everything worked great after that. If I hadn't received the alert I probably would have driven off with it on. I'd probably have noticed the hesitation and checked the break again, but the alert was useful. Some of the warnings in the MFI can appear to be a pain at times, but it's amazing how thorough a job VW has done monitoring the cars systems and giving real time information if something doesn't work. You just have to make sure you don't get info overload from it all!!
