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 code indicates the diesel particulate filter is restricted.This indicates that this filter in the exhaust system needs replaced as it is to restricted to clean with the dpf regeneration that the computer does automatically.This causes the limp mode power you see here.If they did not send your filter off to be cleaned or rebuilt or replaced it this needs done.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
