Hi, my name is ***** ***** I will be happy to assist with this today.In some cases, I may need more info to assist better.I apologize for any delay.
This may be an issue with a sam control unit causing this fault here.The only issue is usually the fault has to be acting up for a dealer to be able to then diagnose and locate the issue.If they did not check for fault codes in all computers this needs to be done.If both issues started to occur at the same time I suspect a sam control unit fault possibly as this can cause this type of issue here.
