Hi Skoda family,

 

I drive Skoda Octavia 2011 1.4 TSI Elegance edition. From some days, airbag warning light popped up in the dash board.
Following info retrieved with the help of diagnostic tool:

Fault Code: 01639,

Error msg: Side airbag crash sensor on passenger side (back),

 

I've been trying to search online to find info about the location of this sensor in my car.

Found some similar info and tried the same but no success yet (may be info is not valid for this model or I missed something in the instructions).
 

I live in nordic region, and car repairs are so expensive here.

I've checked with Skoda also, and the cost of doing the fault diagnosis is about 160£ and later they will share the quotation with total cost of the repair. My plan is to try DIY before going to dealer/workshop.

Can someone help to share some info (pics of service manuals, or a video link) explaining how to:

• access this sensor to know its OEM number (this will help to match the exact part and calibration settings in case I need to replace the sensor after checking all the cables)?

 

Your reply would be very much appreciated.

 

Thanks

According to the information below, this code is used for airbag sensors on both sides of the car; identification of which side is by the use of VCDS software.

There is a helpful video for the VW Golf showing how to find and change the sensor but note that VCDS is required to cancel the warning and possibly to complete the installation.

You can get the part number from the old sensor.

 

 

 

Bundle of thanks for your reply.

I managed to access the location of the faulty sensor.
Cables and connector around the sensor seems to be fine.

OEM number of the sensor is: 1K0909606D.

Checked with Skoda about the cost of the new sensor. It is about 170£.

Any suggestion about shall I go for a new one or buy a old one?

In a 2011 car I would be tempted to buy a salvaged unit on ebay such as this:

Spend your savings on getting a garage to turn off the warning and , if necessary, make software changes to adapt the replacement sensor.

Highly unlikely that the sensor is faulty or has failed, very probable that there is a connector problem.

 

Resetting the warning light will most likely cure the fault until the next occurrence.

I've done the reset at least three times but the warning pops up again after 20-30km of driving.

Does this symptom confirm that sensor is faulty or?

I had similar, it was the cable into the door

To troubleshoot/confirm the cable issue related to this warning (about back sensor on passenger side), do I have to check the cables from airbag control module till the sensor with multi meter, or?

Apologies for very late update on this.
It was the faulty sensor. Replaced it and issue gone.

 

Bundle of thanks for everyone for the help.
