Park Brake Failure

I have the same problem where my car states there is a Park Brake Failure and shuts down the DCS and goes into "Limp Mode". I've taken it in a few times and they say I need to replace the peddal assembly. I've done that 3 times now and still have the same problem. It only happens when it is above 85 degrees out and it gets hot inside the car. What could this be?!?!?! Can I pull a fuse or something to stop the car from at least deactivating and stranding me wherever I go?

    They replaced the pedal assembly at the dealership and the shop, because they said the problem was in one of the connectors that you can't buy separate anymore. I got 1 used and 1 new assembly and neither worked along with the original one that was in there. Which means 3 different assemblies have the same problem??? I just think it's strange that I consistently will not work when it gets to a certain temperature.

You'll have to replace the calipers. I am suredriving with the rear disc brakes partially locked
generated a lot of heat and melted something inside the caliper. Now you can
remove the car's wheels and can move the parking brake arm on the caliper.
The little spring on the caliper that's supposed to retract the parking
brake arm should be strong enough to do it....

you say you replaced the pads, did they fit okay? and have you checked cables and mech parts for freedom of movement etc.
If all okay, have you tried a recalibration to the electronic handbrake?

Sounds more like a throttle position sensor to me. Which , of course is mounted to the throttle body...
and DJAG ,

Thanks for contacting Fixya.

Oxygen sensor fuse blowing causing limp mode and rear brake lights to come on even with sensor runs for a few miles then goes into limp mode

The only reason I can think where a fuse would be used for 02 sensor is the sensor heater circuit, maybe circuit is shorted to ground?

How can I disable the hard limp mode on a 1998 mercedes e'320, drinks spilled on center consoul, next day stuck in second gear a Shifter control was taken apart & cleaned. Still no gear lights up

The shift console has nothing to do with the emissions limp mode.
There is a solenoid to disable the shifter from being able to be moved out of park, but that is in order to ensure you press down on the brake. Don't know what could be wrong except that you might have blown a fuse that powers the transmission.

UndEngine light is on and ve holden omega goes into saftey mode when you put your foot down on the exalirater

With engine off tap the accelerator pedal several times on and off quite hard , this will free up the electronic mechanism that controls the amount of fuel going to the engine.Now start car ,your engine management light(usually yellow) should go out and the limp mode of car will switch off and resume normal driving.If still in limp mode will need error codes deleting from ecu by garage.

you need to have the car scanned for freeze frame data code reading to see what happened at the time of the limp mode...Let me say that at times after heavy rain or even if you wet the fire wall near the throttle body, that can also cause the limp mode coupled with brake, dcs,and gear box fault and engine fault lights etc...You can actually do a hard reset yourself by disconnecting the neg battery terminal for 30 min..Let the car run and take it for a drive to make sure the shift points arent jerky.But have the car scanned and let me know what code comes up.

Transmission locked up, felt like it was stuck in second or third gear. not shifting. shut engine off and restarted , shifting properly now. what causes this.

It was a temporary fault that put the car into limp mode (a safeguard operating condition designed to protect the transmission in case of serious failure). Sometimes a transient fault can occur, and the car goes into limp mode just to be sure it's not for real. Shutting off and restarting the car is the usual way to clear the fault and return the car to normal operation - if the problem was real, the car would've stayed in limp mode after restart, or gone into limp once you started driving again. I wouldn't sweat this one, since it went right back to normal operation.
