Vertical Acceleration Sensor

Hi guys

So I need to get this sensor replaced so I was wondering after fitting does need to be electronically calibrated?

Got the chassis malfunction and EDC doesn't work and from reading this sensor is the culprit.

Any help appreciated.

Thanks

 

Yes a static calibration has to take place once the unit is changed.
Doesn’t take long to change but I think the box and cable are about £150 or something.
My drivers side one went about 6 months ago.

 

What's needed for the static calibration? any special tools? Reason I ask is because I am going to attempt replacing this sensor myself as it doesn't look hard.

 

Service function/start-up VDC using ISTA/X

 

Cheers.

I assume this function isn't possible using bimmercode/bimmerlink?

 

Unlikely i think, but can't confirm 100%

 

Sounds like spun crank hub to me mate

 

Russ help me out !

 

Yeah it doesn’t need any tools, it’s just a case of using Ista to tell the car to calibrate. It then assumes the car is flat and not moving, and reads all the sensors so it knows what the base readings are.
You wouldn’t do this in bimmercode.
It’s a really quick thing though so a dealer may just pop it on for you for a pack of biscuits or something!

 

@karyog did you get this sorted? I've just replaced my acceleration sensor and cable but it hasn't resolved my error codes ?

 

Yep resolved. Had a small issue once I fitted the sensor I had another code come up.

482A22 but disconnected the Edc wire at the top of the strut and reconnecting has now completely resolved the issue and no faults are present.

 

Hi did you perform the re-calibration yourself? - that is the bit I need to do now I think.

 

It has to be done with Ista on a flat surface so the car knows it's level position.

 

Hi I have ISTA but not really used it before - is it straight forward to do? Any guides/steps on doing this?

 

Reading all these comments on 6 year old maximum age cars with all the issues that seem to crop up a warranty extension is definitely something not to be taken out.....

 

Didn't need to do the recalibration. As soon as the sensor was plugged in I cleared the codes with ISTA and it went .

 

If you didn't recalibrate you risk spinning the crank hub

 

That’s handy then. My dealer told me it had to be reset. maybe because mine had totally failed or something.

 

It only has to be recalibrated if the error doesn't go away but usually the car just calibrates itself.
