Generic code for a blocked DPF, as I am sure you will have looked up too. Why put DPF cleaner through the system if there was nothing wrong before? I assume there was nothing wrong before? or was there, and your oil change and and DPF cleaner was an attempt to address the situation?
Generally, if you don't have a cough, you don't start drinking cough mixture do you?
White smoke= unburnt diesel
