What are you using to pull these codes?

 

[TDI2003]

I'm using vw cable.

So many red codes at the beginning. Did you have the power on - not started, just powered on for the scan?

 

[SaVAGeSoot]

Brutal.
What happens when you attempt to clear all codes? Do they all come back instantly?

 

[TDI2003]

 

[TDI2003]

Yes when the vehicle is running I have all this dtc no communication issue

 

[TDI2003]

When I clear all codes they come back when I do auto scan

 

[TDI2003]

Vehicle start and drive but no cluster or HVAC and components theft protection shown on radio display.

Rather than screenshots when you do an autoscan save it and then post the complete saved scan. Much easier to read and understand

What's the story behind this vehicle? Flood recovery or what? Why is such a low mileage unit having so many issues? How did it get to this stage?

 

[TDI2003]

Not a flood recovery vehicle. Customer said at times they were losing instrument cluster at times and one day nothing at all. No aftermarket parts.

 

[SaVAGeSoot]

So have you pulled the cluster to check wiring and connectors? Verified power, ground, CAN?

 

[TDI2003]

Yes power,ground ,can from cluster.

 

[SaVAGeSoot]

Bust out WDs and see if any of the modules that are dropping coms share something.

 

[SaVAGeSoot]

Yes power,ground ,can from cluster.

What pins did you confirm these on?

 

[TDI2003]

2015 VW Touareg dtc u0155 and u0164 loss of communication and dtc u1121. I check can bus low and can bus I have short to voltage. I found on tire pressure module wiring all corrosion. I remove the tires pressure module short to voltage to gone but I still have no communication with HVAC and cluster did the tires pressure module damage the cluster and hvac?

Are you using a VCDS clone copy or the genuine article as the clones can give many spurious results and if thats the case so hard to tell what's the real issues.
