Just got the car back from service all well apart from overfilled oil. The ash content of the DPF is 9g so still plenty of life in it.

22k / 9g x 60g = 146k miles life expectancy of one of these DPFs?

Sounds about right.

This is the second time my DPF is playing up. Once again, the dashboard warning light came up, I drove in third gear at 3k rpm for over 30 miles at constant speed, and now the flashing glow plug is on and engine in limp mode. This happened last month and I had to get an indy garage run a forced regeneration. 

 

I have only been using Esso, using premium diesel every fourth fill up and all my driving is on motorways with a heavy right foot.

 

Why is my DPF clogging up so quickly? Or at 107k miles, is it time for the inevitable?

Hi FSA, I believe you are not clearing the DPF correctly, it should be done in 4th or 5th at a min of 2.000 RPM, at least as per the Manual 

 

This is a direct quote from the manufacturer:

 

 

 What should I do if the DPF

warning light comes on?

This light could illuminate between 10

and 1,000 miles. When the light shown illuminates,

it does not mean there is a fault on the vehicle.

It means the vehicle needs help to carry out DPF

regeneration. The procedure involves the vehicle

being driven in a certain way to help increase the

exhaust temperature. Drive continuously for about

10-15 minutes at a speed of at least 40 mph in

fourth or fifth gear (automatic gearboxes select

Sport mode), to maintain an engine speed no

less than 2,000 rpm. Higher engine speeds are

perfectly acceptable where conditions allow.

If the conditions described are not met and the

DPF warning light does not switch off, the level

of soot in the DPF will continue to increase.

This will increase to a certain level, where two

warning lights will appear together.

 

after forced regen run it, every once in a while on a motorway doing the above and you should have no issues with DPF - I have had none so far following the manufacturer advice.

 

Also be aware of DPF deletes as, if UK will follow central europe standards in any near future, DPF's will be checked on MOT's by measuring soot from exaust and the car will be impounded until you arrange a new DPF to put back in (happened to 4 people already in Luxembourg and just the fine was 2500 Euro plus a heavy increase in insurance as it is considered a mod to the car that was not declared to insurance). Maybe that will not be included on UK MOT and you guy's will be fine ..... really do not know.

Don't forget the instructions for PD and CR engines are different.

True, had overlooked that.

Relevant info; I have been using Ulitmate almost exclusively over the last 2 years. And have carried out interim oil changes as , on occasion, I have had rising oil levels.

Thanks for all your input guys. Since the last forced regen, I've had three auto regens come up and completed successfully. Next time I'm around someone with VCDS, I'll ask them to check the soot levels. 

 

I guess I'll have to start saving up for a new DPF. 

I'm happy to report that so far there has only been one more auto regen (which was completed successfully). Perhaps using Esso exclusively has helped (I used to just go to whichever place was cheapest locally).
