BMW E90 - Steering Angle Sensor - DSC

[Artjom]

Hallo guys.

I have following problem .. coustomer came to me with an e90 335d 2007 that had all contollunits from one car and CAS and DDE from other car...

in all controlunits the VIN was changed ..

I checkes with BMW Explorer from bmw26.ru, VIN is same.

but some controlunits have last AIF(UIF) with old VIN



Problem is that after the guy changed the VIN the active stearing stoped working. Car came to him with all controlunits from one car including CAS and DDE and this idiot could no make new keys so he decited to just put other CAS and DDE to car.



i tried with DIS in service function... to activate the active stearing but always come error 200.134 from DIS , so cant adjust active stearing... but adjust the Steering Angle Sensor is not problem ..


or has the Steering Angle Sensor a VIN so it dont work with DSC ?

Is it possible that the DCS vin is changes but of the steating angle sensor can change vin.. ? because i heard that in E65 the steatring angle sensor has own vin..

check the vehicle order of the car maybe parts brought from a car with active steering and this car doesn't have , in this case you will always get a zero value

[Artjom]

thx for you fast answear... how can i check that?

when i read with DIS .. the active stearing is black but has no x or ! beside it , same with junction block.

both can be diagnosist.. i can read errors and values..

i read the FA in CAS with BMW Explorer and it seemed to active staring there..

how can i check if it is programmed?

The story was like that... in the cars the engine was burned.. so everything was taken from doner car.. the donner car had active stearing.. the original car didnt..

the guy how worked on that car and changes the vins...

as i understood he took CAS from the original car and the ECU from doner car and now active stearing dont work anymore.. but it war working.. when car came to him with orignal cas and ecu..

[tech111]

do you have ncs or anything to read the fa codes in the car ???

if you are satisified with the help press the thanks bottom

[Artjom]

i have full ncs expert but how can i know which code is for which equipment ?

[tech111]

check whether you have S217A , if not add and code the car

[Artjom]

do you have a list ... for the codes so i can see what code is what equipment?

thx

[vares]

ETK for this

[3in1san]

File E89AT.000 in NCS Expert folder contains evrything you need.

[Artjom]

you are right you can realy find all the equipment there.. but i will have a look on etk also.. maybe better to use..

does anybody know if the Staeraing Angle Sensor has VIN?

Can you just take all staring angle unit from different car?

I heard that the E60 has vin in it.. but the e90 not.. can anybody confirm..

[Artjom]

now we managed to make the stearing angle sensor work but can make the active stearing work...

The car seems to be codes right ... we added active stearing ...

but when we do DIS short test.. the active stearing and the junction box are shadowed, as they are in the equipment of the car BUT there is still no X or ! beside.. so as i understand those controlunits dont get the right responce to the car...

Before an idiot changed all vins in that car and made some coding the active stearing was working.. so it must be problem in the programming..

we also had problem with szl (stearingwheel lock) ... but we flashed an update on it with inpa

we also flashed the acvitive stearing module to get the last AIF (UIF) Vin and Vin of controlunit to be same

i dont know if it matter but the last AIF(UIF) Vin and the controlunit Vin of DSC is not same..

Just so you understand.. ECU and CAS and keys were taken from one car without active stearing.. and everything else was taken from other car with active stearing..

We have no idea where to star or what to change first.. one say the steating angle unit dont fit to DSC .. other say junction box is problem ... other say active stearing controlunit..

would apriciate some help..

[cammy25]

Its not VIN ....I think its serial of steering angle sensor.

you must check with Tool32 what serial is programmed in DSC.


2nd thing....if only CAS and DDE are changed , why didnt you get the coding from FRM?? as that should be original

[Artjom]

Ok now i found out.. everything in the car is from the modufication model from that came out 06.2007 ... all controllunits... BUT this idiot that played with the car... he put old CAS dump of 2006 e90 pre modification ...

so he used the original dump of 2006 BUT put it in the new cas that belong to 2007 model ... dont know if it make a difference...


we changed the equipment by nsc expert BUT can not code the car totaly.. because some controlunits like FRM dont responce.. so we codes some controllunits seperately..

can this have something to do with the fact that he used old dump for new cas ?

cammy can you tell me how to look up the serial nb in tool32.. newer worked with it before..

does the serial nb have to match the dsc? .. strange is that active stearing was working before the started programming...


it so frustrating to do this car after some idiot masssed so much up...

please help guy.. this is realy a tough one..

[cammy25]

1st: Check WHY FRM doesnt answer, its very important component in car. if you can fix it, then you can extract PSW trace from there.
2nd: I think all CAS 3 in E90 are same only 318/320d with start stop system differs.


can you please post the FA and all DTC's with exact description?

[Artjom]

here the FA of both cars...

the KZ85610 .. is the car where the CAS dump was taken from

and the other .. is where all controllunits come from includet cas and DDE... just the dump of the cas is from other car...

I attached the dump of cas that is in it now.. and the original cas dump that used to be original... maybe you can compare..


also i atached an picture of all controlunits read out by bmw explorer.. the red makred vin mean that VIN in controlunit and AIF are different..
