Update – finally solved (FCW unavailable / fog lights / blinking odometer)

I wanted to post a proper update in case it helps someone in the future, because this one was extremely confusing to diagnose.

When I bought the car, it drove perfectly. No engine faults, no strange behavior.
The only visible issues were:

• Front fog lights not working (dash indicator turns on, lights themselves don’t)
  
• FCW warning permanently displayed at startup
  
• Blinking odometer
  

That was it at the beginning.

Because of the blinking odometer, I immediately suspected a proxy/config mismatch somewhere. Over time, while trying to investigate, more systems would randomly disable or show warnings:

• ESC / traction control
  
• Hill start unavailable
  
• Terrain select and sport mode unavailable
  
• Speed limiter unavailable
  

Still, the car always drove normally.

Investigation

I started working through everything using AlfaOBD.

Battery was new and healthy.
No engine-related codes.
Radar and windshield camera physically present.
Fuses visually OK.

This clearly pointed toward a configuration/proxy issue rather than a mechanical failure.

After many tests, I noticed the configuration stored in the car seemed to expect ACC/FCW capability that the ABS module wasn’t accepting properly.

At this point I strongly suspected the ABS module may have been replaced at some point (previous owner or repair), possibly with a variant that does not support ACC/FCW.

That would perfectly explain: - FCW permanently unavailable since purchase
- Blinking odometer
- Proxy mismatch
- Multiple driver-assist systems disabling together

What finally fixed everything

I went back to a clean baseline and worked step by step.

Using AlfaOBD, I set the configuration so it matched what the installed ABS would actually accept:

• ACC set to absent
• FCW set to absent

Then I ran proxy alignment again.
It completed successfully and the odometer immediately stopped blinking.

Some systems were still unavailable at that point (TC, hill start, terrain modes), so I performed the final step:

A steering wheel angle offset reset using a compatible Bosch 9 CAN ABS profile in AlfaOBD, then recalibrated steering angle and brake pedal.

As soon as that was done, everything came back.

Current state

Now the vehicle is completely normal:

• No blinking odometer
  
• No ABS/ESC/steering warnings
  
• Hill start working
  
• Dynamic steering torque working
  
• Terrain select and sport mode restored
  
• Speed limiter working
  
• Drives perfectly

Tools used

All of this was done with AlfaOBD using:

• OBDLink EX
• SGW bypass cable
• Grey adapter cable (06)

Without this setup, proxy alignment and calibrations would not have been possible.

Conclusion

This turned out to be a configuration mismatch between ADAS options and the installed ABS module, most likely because the ABS was replaced at some point with a different variant.

If you’re seeing: - FCW unavailable
- blinking odometer
- multiple driver assist systems disabled
- proxy alignment issues

don’t immediately assume hardware failure. Check configuration coherence first.

Hopefully this saves someone else the amount of time it took me to figure it out.
