Hi all,
A bit of help needed.
Just got this message today - "exhaust filter nearly full - refer to handbook".
No mention of exhaust filter in handbook - great
Does this message mean the DPF needs a clean by a thrash on the motorway or what?
Why do JLR suggest I look in the manual for terminology which is not in the manual?
Any help gratefully received.
Tony

Taken from an Evoque forum

The regen takes place when the vehicle travels at more than 40mph for over 20 minutes after reaching normal operating temperature.

The vehicle would need to be travelling in excess of 40mph due to the temperature that is reached when carrying out the regeneration.

Generally the vehicle will carry out the regeneration procedure during the course of normal driving when the vehicle has reached normal operating temperatures and exceeds the required speed. However, should you find that the DPF warning light illuminates, it is advised to make a specific journey where you allow the vehicle to reach normal operating temperatures, then conduct a journey for 20 minutes minimum, maintaining a speed of over 40mph to clear the DPF.

Obviously vehicles being used in built up areas where the vehicle is often travelling at low speeds, you are more likely to experiencing the DPF warning light, which gives the driver the opportunity to then conduct the regeneration procedure.


The speed is mentioned and quoted as it is relation to the air flow across the vehicle which allows the regeneration to be carried out at the high temperatures in a safe environment. LR specifies a speed as due to the range of speeds in various gears, as well as driving styles, it makes it a clearer indication plus drivers tend to feel more comfortable monitoring their speed than any other condition. 2015 SDV8 Autobiography - Black, Cirrus, 22" Style 707 Wheels

And do it soon if it get too clogged you will not be able to regen meaning a new CAT......

Thanks JKay (in particular) and Dixey.
It's only been a week since my last decent run and then five days of short ones.
I will take your advice and take control out for the day tomorrow.
Much appreciated, as ever with you FF guys.

If you have used the car recently, i would run the car into your dealer sir as clearly something is filling your DPF up! There is a well known issue with a temp probe in the NS manifold that fails making the car over fuel... This does NOT bring up an EM light but will give sporadic "engine fault messages”

Thanks Craig.
Just been out shopping, 10 miles each way, mainly over 40mph.
Warning gone so I will stop panicking!

I wonder how effective this stuff would be? Or whether it's better just to go for a blast
