Sensor - Front Crash Removal
WARNING: Vehicle sensor orientation is critical for proper operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Replace and properly position the sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed.
WARNING: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment.
WARNING: To reduce the risk of personal injury, do not use any memory saver devices.
NOTE: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic procedure again.

1. Depower the system. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering in this section.

1. Remove the radiator upper sight shield (8C291).

1. Remove the air bag sensor.
   1. Disconnect the air bag sensor electrical connector.
   1. Remove the three screws.
   1. Remove the air bag sensor.

Which sensor?

do you have an air bag fault? is it a crash sensor?

AIR BAG (SUPPLEMENTAL RESTRAINT SYSTEM) General Information The Supplemental Restraint System (SRS) is designed to work in conjunction with the standard three-point safety belts to reduce injury in a head-on collision. WARNING
The SRS can actually cause physical injury or death if the safety belts are not used, or if the manufacturer's warnings are not followed. The manufacturer's warnings can be found in your owner's manual, or, in some cases, on your sun visors. Depending on your vehicle, the SRS may be comprised of some or all of the following components:

• Driver's side air bag module
• Passenger's side air bag module
• Air bag diagnostic monitor computer
• Left and right-hand radiator primary crash air bag sensor and bracket
• Center cowl safing rear air bag sensor and bracket
• Left-hand kick panel safing rear air bag sensor and brackets
• Air bag warning indicator
• Tone generator (internal to the air bag diagnostic monitor)
• Electrical wiring
• Air bag Electronic Crash Sensor (ECS)

The sensors in the car are designed to detect a severe frontal impact. When at least one of the primary crash sensors and the center cowl safing rear air bag sensor close at the same time, electric current flows to the inflator and ignites the chemicals. The chemicals burn rapidly in the metal container. This burning produces nitrogen gas and small amounts of dust, both the gas and dust are cooled and filtered during the air bag(s) inflation. The air bag(s) split the trim covers open while inflating. The air bag(s) then rapidly unfold and inflate in front of the driver or passenger. After the air bag(s) have inflated, the gas escapes through holes in the bag(s) and the they will deflate.

The airbag module is a serious safety device and should not be tampered with. The entire air bag system ie module , air bags, seat belt tensioners etc are treated as one unit and there fore not a serviceable item or part replacement there of. The module should be located in the bowels of the dashboard (yellow wiring ) and mounter to the bulkhead. Do NOT tamper or adjust any componants.Good luck

you should only have to place the front crash sensor and both air bags and you may have to replace the clock spring behind the steering wheel it usually breaks after an impact i would recommend you have a qualified technician do this work

Only a VW technician has the software to reset air bag faults.

If you have the model that has that sensor in the front seat belts, the belts themselves have to be changed @ about $150.00 or more a piece.
You can call different auto part stores to see if they list that sensor or seat belt, but I have a good idea it's a dealer item only. So plan on paying big bucks.
That sensor is tied in with the air bag.

If you are replacing the air bags, you should replace the front left and right crash sensors, the spiral cable under the steering wheel, AND the center air bag sensor, which is in front of the console. If your car has seat-belt pretensioners and force limiters, you may have to replace them also. You will know this if the seat belts are "locked up". If you do not replace all of the parts, you may get a air-bag code, and the air bags may not deploy next time.
