VW Amarok: Engine Light + Bluetooth Failure Connection

Had the exact same issue with my 2013 VW Tiguan last winter. The problem turned out to be more complex than just infotainment connectivity, it was related to the fuel system control module. When these systems fail, they can trigger both connectivity issues and engine warning lights. The repair required specialized diagnostic equipment to properly read and reset the module. A regular shop attempted the fix initially but could not access all necessary control unit functions. The problem needed VW-specific scanning tools to properly diagnose and clear the fault codes. This type of issue can get worse if not addressed, in my case it started affecting fuel injection timing and engine performance. The faulty module was interfering with multiple vehicle systems since modern cars have integrated control networks. The job requires: Full system diagnostic scan, Control module reprogramming, Infotainment system reset, Fuel system parameter recalibration This is generally considered a serious repair due to the specialized equipment and expertise needed. While independent shops may have some diagnostic capabilities, dealer-level tools are often required for full system access and reprogramming.

Thanks for sharing your Tiguan experience. My Amarok had similar symptoms last month, the infotainment going dead and check engine light popping on. Since these electrical faults can indicate deeper issues, I also noticed some rough idling which pointed to potential fuel system problems. Did you experience any additional malfunctions after getting it fixed? Also wondering what the total repair cost was for the module work and reprogramming? My dealership quoted quite high but I want to compare before making a decision.

After getting my Tiguan properly diagnosed and fixed, the electrical faults completely cleared up. The Function restrictions warning disappeared and everything returned to normal operation. You mentioned rough idling, I actually experienced that too before the repair. The engine light issues and connectivity problems stemmed from a simple incorrect pairing with the end device. Much simpler fix than initially feared. My independent mechanic managed to resolve it for just 45€, which was far less than the dealer quote. The key was finding a shop with the right diagnostic equipment to properly read the system codes. No fuel system complications or transmission problems emerged afterward. The car has been running smoothly for months now with no warning lights or connectivity issues. This kind of problem can seem major due to multiple warning indicators, but sometimes the fix is straightforward if you find the right technician. Your Amarok symptoms sound very similar to what I experienced, so there is a good chance you are dealing with the same type of electronic control unit fault.

Thanks for the input. Finally got my Amarok fixed last week. After dealing with the steering becoming slightly jerky and those annoying electrical faults, I decided to try a different mechanic who specializes in VW systems. Turns out the ignition system was causing the connectivity problems and triggering the engine light. The new shop had the right diagnostic tools and found that a faulty control module was the root cause. Total repair came to 380€, including parts and reprogramming. The brakes were also checked while it was in, just to be safe. Everything is working perfectly now, phone connects instantly, no warning lights, and the engine runs smooth. Definitely worth finding a specialist who knew exactly what to look for rather than going back to my regular mechanic who was just guessing at the problem. Big relief to have it sorted. Thanks again for helping me understand what I was dealing with.
