Alfa 159 Warning Light Chaos: Emergency Call Fix Guide

Had the same issue on my Alfa 156 2.4 JTD last year, and with some basic automotive electronics knowledge, I helped diagnose it. The telematics and emergency call systems started acting up with warning lights. After checking diagnostic codes, it turned out to be a faulty cable connection at the control module. The workshop found corroded pins in the main connector, causing intermittent communication errors. The repair involved cleaning the connections and replacing a damaged wiring section. Total cost was 95 Euro including labor. The system reset afterward cleared all warnings, and everything has worked perfectly since. The actual repair only took about an hour once they identified the issue. Before suggesting specific fixes, could you share: Build year of your 159, Engine variant, Current mileage, Exact warning messages displayed, Any recent work done on electrical systems This will help determine if your issue matches what I experienced and whether similar fixes might apply.

Just had my last service at 111101 KM and can confirm this issue started appearing shortly after. The warning lights first showed out of nowhere but now appear every time at startup. Called my local mechanic and he quoted 150 Euro for diagnostic and potential system reset. Getting quite concerned as the service light has now also started flashing along with the original malfunction indicators. The diagnostic codes from my OBD reader match what you described regarding the control module communication errors. Still weighing my options between a full dealership visit versus the local workshop solution.

Thanks for those details. Based on these symptoms appearing right after your service, this sounds nearly identical to what I experienced with my Alfa 156. The flashing service light combined with the SOS signal errors strongly suggests a connection issue rather than a complete control module failure. The 150 Euro diagnostic quote seems reasonable, but given the timing post-service, I would first check if any connections were accidentally disturbed during maintenance. When my car had this issue, the workshop found that cleaning the control module connectors and securing loose wiring resolved the call failure warnings completely. After my repair, I noticed these key points: The warning lights stopped appearing at startup, The diagnostic codes cleared permanently, No more unusual telematics errors Quick tip: If your car shows similar diagnostic codes to mine, focusing on the wiring connections first could save you money before replacing any components. The complete fix on my 156 ended up being much simpler than initially feared. Would you mind running another diagnostic scan and sharing the specific error codes? This would help confirm if we are dealing with the exact same control module communication issue.

Thanks everyone for the input. After considering the advice here, I decided to book my 159 at the local workshop. They found similar wiring connection issues as described, corroded pins in the emergency call system causing the control module malfunction. The SOS signal errors and warning lights were sorted with a thorough cleaning of connectors and replacement of a small wiring section. Total repair came to 120 Euro, significantly less than the dealer quote. All warning lights cleared after the system reset and no more call failure messages appearing. Really glad I checked this forum first as it saved me from unnecessarily replacing the entire module. The car has been running perfectly for the past week with no warning lights at startup. For anyone facing similar issues, definitely worth checking the connections first before assuming worst-case scenarios. The whole repair took just under 2 hours and all safety systems are now functioning as they should.
