Unable T Communicate to Airbag Control

[carloco]

A few months ago the Airbag light came on. The VAG-COM scan shows no error codes and it says that it is unable to communicate with the airbag control module. I am unable to find any other information. Any suggestions before a trip to the dealership?

Since you're not going to show us the auto scan, what could we possibly suggest except take it to the dealer?

Any suggestions before a trip to the dealership?

Yep:

Post the whole scan here so we can see what this car is made of. Are we supposed to simply guess what car, engine, and modules you've got?

[carloco]

I am going to go and have the car re-scaned. my friend didn't save the first one.

The program said that it was unable to run the airbag diagnostic (15) because it was unable to communicate.

[carloco]

Any ideas? Does this mean anew module?

[Theresias]

Whats the actual bahvior of the airbag light when you switch the ignition on? Does it do ON-OFF-ON or does go straight to ON? Is there an aftermarket radio installed?

[carloco]

Light is solid on and No aftermarket radio.

#1 Check Power Supply/Fuses for Airbag Control Module (J234)
#2 Check Wiring from/to Airbag Control Module (J234)
#3 Check/Replace Airbag Control Module (J234)

[carloco]

According to dealer, It will cost $1210 for parts and labor to replace the module/

[Theresias]

Find an independent VW/Audi specialist and ask 'em for a quote, this seems to be "slightly" on the high side...

[carloco]

Any Experience with reprogrammed or re manufactured control Modules?

[Theresias]

Don't go there! You are talking about a safety feature which in the end is supposed to save your life. I for my self are not willing to take chances on that, neither does VW permit such repairs or reprogramming.

[carloco]

OK, Thanks. I find strange that the thing just stopped working on its own...

[Jack@European Parts]

It is more likely it has failed due to water ingress.

I would take the airbag module out of the car and apart. Inspect for water damage, with a witness, which can authenticate this in writing if need be.

If it contains it.

Take a picture, submit a claim to VW to fix it for free, for water ingress.
These cars are covered for everything on floor such as carpets harness etc.

Hope that helps.

I second the wizard on this one.

Be advised : Some airbag modules in the cars now, are designed for up to 3 deploys and it depends on the accident. If the diagnostics can clear the module through normal means, its OK to reuse.

[carloco]

I am going to take it out and see if there is evidence of water intrusion. If there isn't, Any recommendations for a store that sells the airbag control modules.

Thanks, Jack. Do you carry the Airbag Control Module for a 2001 eurovan? I didn't see it on the ebay store.
