2007 E350
SAS removal
This is for my 2007 E class
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

Steering wheel and tires should have been straight when you started. If so, then just align the line marks at 12 and 6 oclock on the spindle with the clockspring arrows and you should be OK.

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

"ESP inoperative" is not absolutely due to steering angle sensor failure. My experiences with my E280 2007 (non 4matic) is when "ESP inoperative" message appeared, I took it to garage then they found brake switch has not been working. The brake switch was replaced at usd30 then the message ESP inoperative totally disappeared.
My advice is that you take your car to MB dealer to get it scanned before deciding anything.

e320 bluetec 2008
For future reference - removing steering angle sensor
Procedure for the 2008 e320 bluetec. An experienced person can swap this part in 30 minutes. No expereice - two to three hours.
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.

This was so sudden. The wife and an S550 backed up into each other in a parking lot, no body damage as they were just beginning to back out. The S had some blemishes on its bumber though, nothing on mine. Then this morning the light came on then i noticed the alignment was off. I dont think they are correlated though.
You can't swing a dead cat in Fairfield county without hitting an E or S class Benz.

righty tighty lefty loosy.... Your best bet is to find a t-35 since i think the are t-30's and hammer it on to the hogged up screw hoping you indent it enough to get some leverage.
This situation you have come about isn't exactly a good look for you by any means....
