I'm on my third 2.2 mostly doing short trips to school in town on the way to work and have not ever had a dpf problem

I've not heard of anyone having DPF problems with the Defender. It's certainly nothing like as much of a problem as it is with some VAG and PSA engines.
It's really not worth worrying about, but if it did ever become a problem, there is a solution.  |

Some fag packet calculations based on data from the workshop manual:
Active regeneration generally occurs every 250 miles. The active regeneration process takes up to 20 minutes to complete. Speeds of not less than 30 mph are required. When active regeneration is operating, there will be a 100% increase in fuel consumption. Based on my average of 24mpg, 12,000 miles per annum and last years average diesel cost of £1.31 per litre: There are 48 active regenerations per annum. Each regeneration uses 1.89 litres of diesel. Total diesel for a year is 90.92 litres. Total cost is £119.11. So it really is a stealth green tax.  |

I'd take issue with the term "stealth green tax" - there's is absulutely nothing green about it!
The DPF as far as I can tell simply takes yukky large soot particles which make the inside of your nose black but do no real harm and coverts them into microscopic and probably carcinogenic particles which lodge in your lungs and cause real harm. That is not not really 'green'! |

I just got a 2010 Defender 90, it's actually on it's way to Kenya now
 Can't wait… Anywho, Kenya does not boast the cleanest diesel. With that said, I'm hoping that the 2010 Defender 90 2.4 does not require a DPF. Could someone please confirm this for me?
Many thanks! |

2.4 does not have a dpf
2.2 does have dpf |

Hi Supercat,
"Active regeneration generally occurs every 250 miles. The active regeneration process takes up to 20 minutes to complete....." Apart from the increased fuel consumption, how do you know "Active regeneration" is happening? Cheers Mr Don |

Regeneration is not noticeable or at least is not supposed to be.
There are a number of things happening that you could potentially use to let you know but essentially the only designed in feature would be if you get DPF FULL message and then you drive the vehicle until the engine is at its normal operating temperature and then drive for a further 20 minutes at speeds of not less than 30 mph (48 km/h). As successful regeneration of the DPF is indicated to the driver by the 'DPF FULL' message no longer being displayed, you would then know that it had just happened! |

Unlike other diesels I've owned with a DPF, I have not felt any difference in the throttle response or ever noticed an active regeneration. I did once notice the footwell getting a bit hot and (as you say) you can almost see the fuel gauge dropping. The active regeneration strategy seems to be a lot more aggressive than other cars out there, which seems to do a good job of keeping the DPF clean but I have seen the oil level rising due to diesel contamination (even with a change at 6,000 miles) and mine was flagging up that it needed an oil service before the 12K/12month interval. This is based on a calculation of 7% diesel in the engine oil from the number of active regenerations. It's easier to change the oil than the DPF though! |
