I have it on my TDV8, is standard here. No problem with it. I also had it on the TDV6, different type, it was an add-on(was already on the car) and also no problem. I heard few people having problems with it.

The procedure for clearing the DPF is in the manual.....if you drive fast enough most of the time, then it stays clean. |

I now have 8500 Km on the TDV8, never had the DPF full message yet. I do quite often a bit of highway, lets say couple of times a week. '08 RRS TDV8

At ~25,000 Km's on my 08 TDV6 and no problems with the DPF, never had a message. i hear it carrying out the burn cycle every now and again as it makes the engine sound slightly different on start up! |

OK. The exhaust emissions are a complex mixture of solid and liquid components. These are going to clog up the DPF. That's why it gets full. However, the DPF is able to regenerate, meaning the obstucting particles trapped in the filter can be burnt away so that the exhaust gases can flow freely. This process is not noticeable by the driver. DPF regeneration is controlled by the temperature of the exhaust gases and the DPF. These in turn are controlled by the DPF software located in the ECM. The DPF software monitors the load status of the DPF and also other signals from different pressure/temperature sensors. When the loading reches a predetermined level, the DPF will start the regenerating process. There are two processes involved, passive and active. Long story, so we shall not go into it now. Anyway, if the above regeneration is not working in your vehicle, it could be the software problem in the ECM or any of the pressure/temperature sensors. Its Saturday morning here and I've not had my coffee yet! Please excuse!

Bobby, not meaning to question your omniscience about all things RRS... but I would suggest it is noticable to the driver as the engine noise changes slightly whilst the burn cycle occurs.. IMO anyway! |

30.000 kms on the clock and no problems... Maybe the 2-stroke oil mixed with diesel helps? |
