Mercedes C320 steering column & seat convenience feature

Speculation without further details but 3 usual causes:
1. Clock spring in steering wheel for airbag open circuit.
To Test - disconnect battery-disconnect airbag ribbon from steering wheel -insert 3 -8ohm resistance bypass in airbag plug below steering column feeding clockspring. reconnect battery and see if light goes out after 5 seconds
2. Check passenger seat sensor operational.
To test - with ignition off - disconnect plug under passenger seat for sensor pad and insert test ohm resistance in feed plug. switch ignition on as test 1.
3. Check steering wheel button operation. if any radio actions do not work problem may be infrared link between steering wheel and radio (especially aftermarket modules)

there are probably small plastic lock pins that take up the slack in the column
these break of when a heavy pressure is applied to the wheel either by the drive or in an accident to allow the column to collapse
the fix is a new steering column
check the steering column for failed "U" joints or flexible connections
Take it to an accredited specialist steering shop for a proper diagnosis

Unfortunetly the only repair for that issue is to replace the complete seat belt mechanism. Basically the internal winding mechanism has gone out and will not retract the seat belt.

Two FLASHER applicatiosn there:
Hazard flasher: Front seating area, driver side, under dash, driver side of steering column, mounted in convenience center

Turn signal: Front seating area, driver side, under dash, driver side of steering column, mounted in convenience center

This is one of the feature called easy access. You can go to the setting from menu at the buttons on your steerling wheel to turn it off then it will stay down. It is under convennient set up, go to steering column and select off.

The gear oil needs cheching via a computer and probe that normaly only main dealers have , and the engine oil if it has no dip stick it needs cheching via a program on the steering wheel. consult manual for exact procedure.

There is a fuse to protect the circut operating the electric steering lock.

There is a rubber dogbone connector that hooks between steering column adjuster and motor mechanism. This piece is broken. It should be replaced by a trained technician due to the complexity of removing part of the underdash panel, steering column, and instrument cluster.
