Where is a picture of the 4 ABS speed sensors?

Your talking about the speed sensors? Those are not always easy to get out. Esp the back ones as ive had to remove the parking brake assembly a few times to get them out. Should take an hour, but on occasion it is a much harder job.
I'm trying to find a picture of the ABS speed sensors in my brake thread but I can't find any pictures that look like the sensor.

I can find the sensor CONNECTOR but I don't know which picture shows the sensors.

Here you go...

Sensor in the rear Passenger wheel hub.

I wonder if the Sedan's wheel hub is different that the Touring's. Access to the Touring wheel sensor is pretty easy once you get the road wheel off. Two minutes to unscrew it, three if you have to twist it back and forth.

I can see you have never changed one that is frozen solid in there. If this happens you cant just twist it back and forth (that is terrible advice as they can break in half) you have to remove the brake disk and parking brake assembly, and use vise grips with a screw driver to extract the sensor. Re-assembling the parking brake is a b*tch too. Most of the cars with over 100k are like this, and if I was doing that job for someone I would charge 3 hours labor.

I'll consider myself lucky as mine wasn't frozen. Came right up as it was snug, but not stuck. The twisting I did was as it was coming up. I'll remember your advice if I encounter a stuck one. Thanks!

Is this the location of my E39 ABS computer control module?

I'm confused.

The thing that looks like the ABS computer is on the wrong side of the engine (it's on the passenger side, not on the drivers side).

Is THIS thing (see picture below) the ABS computer on my 2002 E39?

Tamper dot came on

Hello all,
I replaced the LCM on my 97 E-39 sedan with one I picked up at a salvage yard. All of my lights are now working fine. The tamper dot came on as the replacement part was from another vehicle. My concern, is this tamper dot something I need to be concerned with as I'm about to hit the road for vacation about 1600 miles and is there danger of harm to other systems on my vehicle.
Took it to a indy shop to have it coded they came up with the fault code indicating the mismatch.
Help please!!!!!!1:mad:
 
the car on the right in the pics above must be a UK car or a mirror image :\***8230;..unless they flipped the washer tanks around too.

No harm will come to your car if you drive with the tamper dot, but it's going to be difficult to sell the car. The dot's there to prevent sale using false weights and measures. Preferably make a new thread if you have an unrelated question.
 
Yes, that's the module, there are 6 torx screws I believe.
Bluebee or anybody else; Do you happen to know how are the abs pulse generators supposed to read? I took both of my front ones off the wheel and they both go to infinity (open) when read, I tried different scales just in case I'm loosing my mind. I thought they were supposed to read something like 4 MOhm. If that's the case, then both left and right fronts are gone on my car. I also have the nice tro of amber lights...
 
I had success, but it likely cost me $105 for a module re-build that I didn't need. After getting the three lights of death, I just flipped a coin and sent the module off to ATE for a lifetime guarantee rebuild. They advised they would test it first, but rebuild it even if it checked "ok" as the heat will get it sooner or later. Got it back and the errors were still there. Did the "diode test" and 3 wheel sensors showed just fine and the front passenger was open-clearly bad. Replaced it for $65 from AutoHauz and all is good once again. Don't even need to clear the error. It clears itself.
 
Puuuurrrdy Subframe bushing... sorry, being a fellow Touring owner that was the first thing I noticed :rofl:
Thanks! Swapped all four out 60 or so days ago... BIG difference...
 
Where is the steering angle sensor? I'm assuming that the angle check are position measurements like a wheel alignment?
I'd be interested in knowing that too... :D
 
""""Here is a link to so you can see the steering column in an exploded view. You'll be looking at part "9". There are 3 different sensors steering angle sensors listed. I picked up a new one from FCP Groton for 260 shipped (it is an OEM sensor)

I could not copy the file from TIS. Here is what the document states. It doesn't seem like much help unless you have a BMW diagnosis system at your disposal.

document number 61 31 996 Carry out steering angle sensor adjustment
IMPORTANT
In vehicles with active front steering, steering angle sensor adjustment is integrated in the service function "Initial operation/adjustment for active front steering" and must not be carried out separately!

NOTE:
Steering angle sensor adjustment must be carried out:
- After adjustment work on the front axle/steering
- After all mechanical work on the steering system
- After the following components have been replaced/coded
- Steering column switch cluster
- DSC control unit
- ARS control unit

Connect vehicle to BMW diagnosis system.
Select and carry out steering angle sensor adjustment under Service functions.""""

I found this post after a search for the steering angle sensor, pricey little bugger...
