When driving my 2004 x5 the 4x4 light and the ABS light comes on.
Sometimes the Trans fail safe message appears also. I have noticed it usually only happens when the car is cold or has sat outside the garage overnight.
Here is what I do.
When the light comes on while driving. I stop the car, place it in park and turn it off. I lock the car and set the alarm. Then I unlock the car, all while sitting in the drivers seat, strart the car and the message and the light dissapear?????? Can someone please help
Re: When driving my 2004 x5 the 4x4 light and the ABS...
There are a large number of issues which can cause a failsafe condition, have the faults read by a BMW shop, this is the only way to pinpoint the problem. Could be a speed sensor, control solenoid, or voltage supply issue.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Could it be a broken abs speed sensor wire to one of the wheels . And for the hand brake sometimes on vehicles with the handbrake between the seats some junk will get in between the brake lever and the down position causing the light to intermittently go on or could be a switch or wire thing again .
Don't mess with the ABS light get it diagnosed and fixed. Your brakes will work with the ABS light on but you will skid because the system will switch to basic hydraulic action with no control of how much to each wheel. If ABS is on then it is not working.
This is most likely one of 2 things 1 the abs sensor on one wheel is faulty, not uncommon cost about $80 for a new one. or you can clean the old one as often they get dirty from brake dust.
secondly the brake pads may need replacing, the ABS warning light is to let you know that these may need replacing, often when it is the brakes they will fel different as you press it down, sometimes they push back up towards you as your pushing down. I would have the back brakes checked as that is normally the cause.
you can still drive the car no problem. hope that helps Regards Dan
Sometimes.... Sometimes this will take care of some of those faults and codes, and it only takes a few minutes to do. I know your problem is not exact as this reset method says, but however you would be amazed on this fixes a lot of things, it like a cheap way to reset computer and fixes a lot of things back to default mode. Try it and let me know. Mike
IT'S VERY EASY TO RESET THE TRANSMISSION'S COMPUTER. HOLD GAS PEDAL DOWN. TURN THE KEY TO THE NUMBER TWO. CONTINUE TO HOLD THE GAS PEDAL DOWN FOR THIRTY SECONDS.RELEASE THE GAS PEDAL AND PRESS THE BRAKE PEDAL FOR TEN SECONDS. NOW YOU CAN TURN THE VEHICLE ON. THAT SHOULD TAKE IT OUT OF SAFE MODE
Your ABS likely has a very dirty reluctor (can happen if the teeth get mud or brake dust in them) or possibly one of your speed sensors is starting to weaken and is close to failure. The proper diagnostic sequence is to have the trouble codes pulled from ABS and Engine modules and determine what the computers SAW when the lights were turned on. Most likely based on description, your ABS will have a speed sensor code, and your engine and/or trans module will have a transmission related trouble code. Very few transmission codes are things you can service at home, usually youll see solenoid or gear slippage codes...mostly those require internal repairs that often require removal of the valve body or rebuild of the transmission.
Make sure you check fluid level, that is the most common cause of transmission slippage codes, however if fluid is full, it indicates that unless the fluid has failed completely, you may need transmission repairs.
It appears that there may be moisture getting into one of the sensors tied in to your abs sensor or your tcl sensor. It's usually not recommended to be driving when the abs light is on because it can indicate a failure and it may not work when you do some abrupt braking
A faulty VSS (Vehicle Speed Sensor) or related wiring can cause both of your problems, trans and ABS. If the computer doesn't know the vehicle is moving, then it won't shift the trans. If the ABS controller sees wheel speed, but not vehicle speed, it will turn on the ABS light. The VSS is located in the rear transfer case housing. But remember, it may be the VSS, related wiring, a faulty speedo buffer (usually located in the dashboard), ECM, or even the reluctor on the transfer case output shaft. You may want to have a shop scan "data stream", or even have them diagnose the problem.
The ABS control unit does need to be coded to the vehicle. After coding the control unit, an End-Belt run test must be performed. I know that you will also have transmission faults stored, because the Trans warning is set since the control unit has not been coded
and the control units communicate constantly during engine operation. The trans uses abs input for shift characteristics and helps with power reduction during evasive driving control. A dealer should be able to code and perform the end run test and usually charge about an 1hr fee. They will also need to quick delete other fault memories.
