A few owners on HK have faced ongoig and bizzare issues with DPF which has baffled Honda as well us to why this has happenning ..well finailly we have the proper LONG term fix Honda was working towards. Honda have issued a Techinical Service Bulletin Number SO-03-001-00 dated 24-03-2014 for the all CR-V I-DTEC with the 2.2 engines made in 2013 and 2014. The Symptoms 1. The DPF system malfunction warning lamp is illuminated. 2. The driver will also detect a reduction in engine power. 3. There are no DTCs indicated when the car is scanned. The Cause An investigation established that there was no mechanical problem with the DPF and the concern was due to an ECM software calibration error which caused excessive PM (Particulate Matter) to accumulate in the DPF. The Fix The ECM Particulate Matter (PM) data setting has been modified and optimised to stop excessive PM build up in the DPF. Honda (UK) is in the process of write to customers with affected vehicles to advise them of this update and ask them to book an appointment with a dealer to have this work completed at the ealiest. The dealer will update the engine ECM using HDS software version 3.012.033 January 2014 or later.If the DPF is found with excessive DP then it will be force regenerated befofe the update. Cars under warranty will have this fix applied free of cost. If the car only needs an update the dealer will take 30 minutes to update to the latest code , if a regeneration is reuired you can add another 40 minutes.
