DSC/4x4/ABS/BRAKE/Traction/SelfLevel Susp. Inac ERRORS
I have an 05 4.8is with around 56k miles. Every time I start the car and drive 5 feet, I get ABS, BRAKE, and traction light come on, followed by "DSC/ 4x4 Inac." on the DIS, then followed by "SelfLevel Susp. Inac." I know the second DIS message is very common on X5's, but does it usually proceed all the other messages? The car isn't in limp mode (can drive up to 65mph) but the car feels funny. Really don't want to go to stealership, but may have to.....
BTW, front struts were replaced 2-3yrs ago with Arnott ones. Never received a message when those went out and I had GT1 calibration/reset after replacement. Also, disconnected battery and checked fuses, all fine and problem still there. What do you guys think it is? Air module behind glovebox? Thanks |
when was the battery last replaced?
|
Battery was replaced 2 yrs ago with OEM one. It is still "green eyed." Also, it is put on a trickle if the car sits for more than 3 days.
Also, Dinan stage 3 was installed in Nov. |
May be alternator/regulator
I had your symptoms. Battery was dying and scan showed alternator problem including overcharge to 15.6 volts. Don't ask me how or why. This was my experience. Battery and alternator replaced and no more issues.
Good luck. |

I'm use a CTEK 800 trickle which has "patented" technology that doesn't overcharge the battery... I don't think this is causing the problem, since Porsche, Aston Martin, Ferrari, and Bentley use this trickle on their cars! |
just guessing here....perhaps some sort of sensor involved with the stability system??? it is suspect that it happens after the truck is moved versus directly upon start up.

Especially if you had any recent suspension work. Something might have been knocked out of whack. Someone replaced a wheel bearing and was installed backwards that gave the trifecta lights. Also might look into the steering angle sensor. That's the sensor which can be reset by usually turning the steering wheel lock-to-lock and clearing the trifecta of lights. |
I had the same issue then after a while of ignoring ( 1 month) my abs would actually engage when I would be between 5 an 15 mph in traffic.
I started driving with the voltage read out on test 9 of the DIS and noticed when the abs kicked in while in traffic that the voltage would jump past 16v. I decided to replace the voltage regulator and it corrected the problem. No issues for the last 16 months. Not saying that its the solution for you but I took a chance since it was a cheap part (about $60) and was a straight forward diy. |

My wife complains that sometimes, and only at slow speed, that it feels like the brakes are engaging and that she feels it through the accelerator pedal too. I've ben trying to replicate this problem but have had no luck so far. Did you actually get the ABS light? She said no lights or warnings come on when it happens. When I get my GT1 back I'll scan for codes/faults. Looks like a voltage regulator is a little over $100 through ECS for our 4.8. Wonder if I can replace it without removing the alternator.

I was first told it was the alternator... Replaced it... no The whole time I kept asking to replace the DSC/ABS control module. On the 2001 x5 it is located behind the front left head lamp. This removed the ABS/Trac/ Brake lights. This worked for my vehicle, I am only suggesting it as an option not the solution. Good Luck. |
Well, at the dealership now. They have been looking at it since 9am this morning.... Just thinking of all the labor they will charge me..... urgh!

Hopefully, they'll just charge you a flat rate for diagnosis. Let us know what they find or don't find. Here's to hoping its something not too expensive! |
Oh man the dealership... last place I go. But good luck sir!

Kept happening as I would try to accelerate and I could see the display on my dash show from 16v to 18v and would fight the X to pick up speed (proabably at 30mph and up) it would not happen and I would pull over, stop the engine, and wait a while before I tried moving again. Sometimes the trifecta will display and sometimes I would get into fail safe mode as well untill I stop, wait, and restart as well as turn my wheel all the way left and right....what ever it took to get home. And ONLY at traffic after driving for a while. Bought BMW X5 545 645 745 Alpina Valeo Alternator Voltage Regulator 4.4L OE @ $69.45 from American Engines Co. Product List You will have to remove the alternator and unscrew the old v.regulator and pop this one in. Still driving great. |

However, I did do the OBC diagnostic test and voltage usually is at 13.9. Hard part is: 1. Trying to reproduce the problem 2. Monitoring the voltage 3. Avoid getting into an accident while driving trying to accomplish #1 & #2 above. Sorry for the hijack lemans. |
Sorry to crash in on the thread but I seem to have the same problem. Just did a 5000 km road trip up the coast and back. Stayed a couple of mornings in Blue Mountains.
Each morning was 10 degrees C and each cold start car electronics went haywire....DCS, 4x4, tire pressure mon, abs, trans fail safe, engine fail safe, park brake on warnings galore, monitor on and off. Warnings would gradually clear once temp went up and car had been running a while. Checked on-board voltage was 12v and once moving hovered between 14 -14.3. Battery was checked by mechanic prior to leaving. My bet is the battery is bad given I only had these probs in the cold and it is an old battery now. |
Got a call from the dealer today.... Apparently, two modules/sensors on the transfer case went out and they also want to replace air suspension module. The transfer case sensors will cost $1500 and $500 for air suspension module.
|
Sorry to hear that lemans,
I'm starting to fear something much worse than the battery. I have read a lot of threads regarding the tri-fecta of lights being caused by faulty T-Cases. Most seemed to replace the actuator motor. |
I told them to just replace the transfer case motor and steering tilt sensor. If this doesn't fix the problem, then we will continue to replace other parts. If this doesn't remedy the problem, then the old parts will be put on ebay for cheap!! haha

If not, is it because you aren't going to replace the air suspension module too? I would be upset if they ask me to spend $1K-$2K or more dollars and it doesn't fix my problem. |
yeah, they can't guarantee that this will fix the problem. But they are "unable" to communicate with the air suspension module and "it is an entirely different system" than the 4x4/dsc/transfer case system.
I just thought it was odd both of these problems showed up exactly the same time (down to 5 seconds at most) so I'm going to see if this helps. If they don't fix the problem, I'll go elsewhere. |

At least double-check to make sure the wheel sensor is clean or not malfunctioning. Especially since they're going to replace the steering angle sensor. |
problem solved.....new one arises
Well good news is it looks like the battery had bitten the dust, bad news: on the way to the mechanic the rear sunroof panel mechanism gave up:rolleyes:
Hopefully the repair kit has the necessary part, but needed car back for work so the roof is permanently closed for now. I have come to the realisation that cars or at least this car are disposable items rather than work horses. |
Car is back from dealer. All problems gone. Transfer case actuator and steering angle tilt sensor were causing all the problems
