hi guys wondering if you could help me.

ive got 2007 facelift e320 i had issues with horn, paddleshift and multifunction controls on steering wheel. i now have changed the steering angle sensor and everything is working back to normal only issue now is my dash board and "esp inoperative" displayed and car is in limp mode.

anyone experienced this? or know anything about it?

IF you have the battery disconnect, just drive it a while it should self clear.

marfaan

ive driven it for about 10 miles makes no difference

Plutoe

One ---do you have distronic?? and two, regradless of number one, did you follow the very specific and detailed WIS instructions pretaining to the installation of the steering angle sensor???

marfaan

i installed the angle sensor with a mechanic instructions and yes i do have distronic

Plutoe

The mechanic realizing that you had distronic did not know that DAS Xentry had to be used to finalize the install and initialize the newly installed sensor to the distronic system.

Not knowing that important install fact leads me to believe that although he gave you instructions on how to install the sensor-----he really did not know how to properly install the sensor-----so know you are confronted with two issues---is the sensor really installed and positioned correctly? and two if it is, then you need to finish the install with the DAS Xentry diagnostic system.

marfaan

will the star diognostic sort this issue out? i have a friend with star machine, is it done in a certain way?

Plutoe

Yes, as long as the version number of the tool is equal to or greater that the age of your car, but I am assuming that is the case, but I would ask!

marfaan

he claims he has the 2012 software so im assuming it will do the job

marfaan

right i have xentry put on and its coming up as angle sensor faulty.
my question is would the horn and multifunction still work if angle sensor is faulty?

marfaan

and also i dont have distronic says my mate i always thought i did

Plutoe

Once again I am assuming, but after you plugged in----you did a quick test in Xentry---yes-------- if no go back and do a quick test to make sure all the other modules are ok and you have reconfirmed that the angle sensor is faulty.

Did you purchase a new MB part or did your buddy sell you a used angle sensor?

If new, my guess is that the sensor was not installed correctly?


I did not answer your question because there are many more questions that apply----worry about the horn later!!

marfaan

i had bought one off ebay and i guess it must be faulty. the seller claimed he bought it from merc dealers and didnt need it. they cost alot of money.

Plutoe

In all the confusion we both forgot about this fact:The original sensor was faulty----there was a resulting fault------did you clear the fault? Or did you just replace the sensor without clearing the fault-------my thinking is that you installed the sensor correctly, but then did not clear the fault.

What I would do to confirm the condition of the e-bay purchased sensor is just clear the fault----then run the car around because now you say you do not have distronic and therefore distronic does not have to be adjusted to the new sensor-----now after clearing the fault and running around---------do the dash lights come on----if they do then I would suspect the sensor is faulty, but if the lights do not come on you are ok!!

marfaan

took car on long drive today realised the tracking is out could this make esp light come on?

Plutoe

Connect Xentry and determine if steering angle still has a fault!!

marfaan

yes. i have bought a new one from MB. what is the correct procedure to fit the angle sensor?

Plutoe

I will write something up for you, however before doing so post your VIN!!

Plutoe

I had trouble with WIS and your VIN therefore I will use a generic 211.022 after mod year 04 for reference. However EPC read the VIN(datacard) correctly therefore there is nothing wrong with the VIN.

FYI all my excerpts are from WIS doc AR4610P0300TA.

The very important point is checking and turning the position marks(arrows) of the sensor and the inner race to the center position-----to do that---

turn(GENTLY) the inner race counterclockwise to it's stop point------then turn clockwise approx two revolutions until the arrows on the sensor and inner race match up.

Don't forget to clear the fault before you take everything apart--Good Luck!!

marfaan

hi ive followed your instructions and still no joy esp light not wanting to go off. ive even had the car tracked.
ive made my mechanic show me all faults showing on the star and it comes up as " steering angle sensor not initialized" is there something else that could be wrong or what??

Plutoe

That's good news------no faults------now you have to adapt the sensor to the car---start in control modules---then adaptations---find your module and then follow the instructions.

PS: Your mechanic should be very familiar with the process!!
