how to replace the steering angle sensor DIY????????
Step1 - Take off the airbag (loosen the 2 hex screws at the back of the steering wheel)
Step 2 - Loosen the 2 airbag plugs green & yellow by lifting the yellow plug locks on them - you can use a small flat driver
Step 3 - Get a helper to hold the steering wheel while you loosen the 10 mm allen bolt , dont strain the steering lock while loosening
Step 4 - Have a close look at the exact posision of the steering on the splines before removing or better just mark it
Step 5 - Undo the 3 small hex screws holing the SAS onto the column assembly
Step 6 - Undo the 1 hex bolt at the bottom of the steering coloum (faces the floor)
Step 7 - you need to pull off the entire column assembly. (Grab the column and tug gently)
Step 8 - Look at the oposite side of the entire assembly (end that faces the firewall) and remove the two Hex screws .
Step 9 - the SAS needs to actually twist off of the column assembly (if you look at th new part it makes sense)
remove, replace and reassemble.
There, you saved $400 in labor

Hi - I have to do the same job. Did you have to remove the clockspring module before getting to the SAS? Also can you explain Step 9 and how did you ensure the new SAS is exactly in the center position. Thanks
BUT YOUR PROBLEM SOUNDS MORE LIKE A BRAKE PEDAL SWITCH WICH CAN THROW THE SAME MESSAGE IF I WAS YOU I'D TRY THAT FIRST CUZ THATS THE CHEAPER LET ME KNOW IF THAT HELPS!!!
asically i read if your car keeps receiving a error message that states ESP INOPERATIVE and cruise control not available it is your steering angle sensor! another thing my car is doing is on start up it doesn't go into gear sometimes even after i hold down the brake, so i am guessing the car thinks the wheel is locked due to its steering angle sensor. correct me if i am wrong. thanks
My advice is that you take your car to MB dealer to get it scanned before deciding anything.
Steps:
1) Steering wheel center straight.
2) Remove ground strap from battery - 10 mm box end wrench.
3) Remove two bolts behind steering wheel - torx 30. Lose bolts stay in steering wheel.
4) Pull air bag from steering wheel. Pull black wire straight off air bag. Using a dental pic, pull up the orange locks on the green and yellow connectors. Then pull connectors straight off. Lay air bag to the side.
5) Pull straight off the lower black connector on the steering wheel.
6) Remove 10 mm allen bolt at center of steering wheel. Notice the steering wheel is indexed for proper install. Remove steering wheel while threading the air bag wires through the steering wheel access hole.
7) Remove one bolt at bottom of steering column - torx 30.
8) Both hands, pry steering column towards you, it will seperate from the steering shaft and be removed from the car.
9) On the bench, remove three torx 10 bolts on the steering wheel end of steering column.
10) On the end of the steering column facing the firewall, remove two torx 10 bolts. End of hardware removal.
11) Rotate/pry old sensor off and install new.
12) Don't skip this step. The new sensor must be activated. After buttoning everything up, start motor, at idle, turn steering wheel full lock right, then full lock left, then back to center. End of procedure.
