ESP light on Merc 320CLS

[colin 320cls]

Just had new steering rack fitted on 320cls but now have warning light "steering angle sensor" fault.

Any idea if this is related to the rack change and how to cure it..tried locking wheels left/right several times but no joy

steering angle sensor

correction to my earlier post warning on dash is ESP but when attaching STAR machine it throws up Steering Angle Sensor"

Replaced sensor but ESP dash warning/steering angle sensor fault still there done wheel lock several times to no avail.

Indie says there is no data coming from the Steering angle Sensor unit so he cannot re align it.

Anyone with any ideas please??

thanks
