    Under certain driving conditions some cars may have problem with overfilled
particle trap and overpressure at the DPF sensor. These driving conditions
causes the overfilling/ overpressure as the automatic regeneration will not
start.
    
    
    
    
    
    
    
   
   
    
   
   
    New SW 55 56 39 43 available at IRIS 2006-03-10 on TIS 2006-1 update
1. This new SW has been recalibrated to enable a regeneration under these
troublesome driving conditions.
    
    
   
   
    Perform a SPS programming of the Diesel engine management system with
the new SW.
