I think the general point is, that with a blocked DPF you have to do something, and although there may be some hacks that might work, having a proper clean might work out cheaper than going for the hack and finding that it hasn't worked and being then charged for a full clean.
My experience is that there are dirty engines that have been modified to work with DPFs as a solution and they are prone to DPF issues and there are newer engines that were designed to run cleaner. The OP doesn't say how old his Beemer is, but I suspect it might be an early DPF model - cruising on a motorway should be perfect DPF territory unless he is thrashing it with lots of foot to the floor acceleration which produces soot. Apparently, blocked DPFs can then cause high oil level warnings as fuel is forced into the oil system so not worth messing with.
I drive my 220 Merc in all sorts of unsuitable conditions - short town journeys) and don't do a massive mileage and yet haven't had a hint of DPF issues, I think because it was designed for DPF at the start and I don't floor the accelerator (and it is automatic and can manage engine revs appropriately so it is always working efficiently).
My Passat is 2016 and it had DPF issues from within a fortnight of me getting it at a year old with 16,000 miles on it. VW replaced the DPF at 20,000 miles, after it had been in for various forced regens, etc.
My brother has a 2011 C250CDI Sport and hes having DPF problems with it too.
Wholly agree RE: the like of Cataclean being a viable, proven product - its the "just stick it in your fuel tank" solutions that arent going to clear out a DPF.
If i had DPF problems i'd probably go down the full DPF off professional clean - but TBH i'm galled that a 2016 car can be affected by DPF issues so i'd say i'll flog it and replace it with a petrol car before the warranty expires in 18 months time.0 -
2 of the best DPF fuel additive cleaners are Archoil AR6400d http://archoil.eu/wp-content/uploads/2012/10/ARCHOIL%20AR6400-D%20Product%20Tech%20Sheet%20Europe.pdf
and Forte DPF Cleaner and Regenerator

Both are well regarded as effective unless there is a specific reason why the DPF is full.0 -

"that quickly and safely remove gum, varnish and carbon
deposits from the fuel system and engine" - doesnt mention DPF. This will not clean a blocked DPF. It cant.

Helps keep a DPF clean, but will not clear a blocked DPF.

You mean like the O/Ps DPF being blocked?
There is not a mission that either of these can unblock a DPF just by adding it to the fuel. They might help keep a DPF clean, they might prolong the DPF from eventually blocking up, but they will NOT clear a blocked DPF.0 -

What I've heard of is back street garages gutting the DPF as the DPF isn't inspected itself, just that it is present.0 -

Yup. They can only check for the presence of the DPF unit, not the contents.0 -
Read the ingredient in a lot of the injector and fuel cleaners, for diesels its often paraffin or similar products.Basically ,yes, I think so .
Or they may apply external heat, blowtorch, blow air through ?? I don't know
Probably not, they may just trigger a regen leaving it running at high revs, as the car is not moving there wont be much airflow through the radiator so it will get warmer than normal.
I guess so, but more like lab conditions
ie it wouldn't be under load, and could be precisely monitored
Nope its going to be in the yard most likely unless they have pipes to vent the exhaust outside.
Id almost certainly blow it up if I tried to do this on the motorway
It wont blow up, your not red lining it, 3500rpm will do it. Whatever gear gets 50-60mph around 3500rpm. It wont redline until approx 5000+ on that engine i think?
When driving do you boot it? Diesels like hard acceleration every now and then, that blows the build up of soot out the exhaust.
Yes, it does sound rather unlikely when you say it like that
Running whilst parked wont put the engine under much load.
Is that a serious suggestion ?
A diesel specialist said he puts in 4 or 5 litres of vegetable oil into his car every now and then. He said it removes laquers that some diesels leave behind.
The first time its used the fuel filter will probably need changing soon after as it catches the muck removed from the system.
As post 16, If they do not take it off to clean if properly then they are doing little more than a thrash up the motorway.
After getting it done you need to thrash it every now and then, that doesnt mean taking it to the red line, but just hard acceleration on slip roads etc, where safe obviously.Censorship Reigns Supreme in Troll City...0 -

The OP said
` I have had it at a garage on the computer and apparently the DPF is blocked and requires regeneration.
This is quite expensive so i was wondering if anyone has had any results from the various fuel treatments that can be added to the diesel tank ??`
As a completely blocked DPF cannot regenerate I offered the above treatments as possible solutions to the OPs DPF which presumably still can and is why he asked.
The Archoil product I shouldve quoted is AR65000 -

To the point of actually inhibiting the performance of the car suggests its "blocked" beyond being able to be cleaned by some potion in your fuel - "My car (BMW 520d) has started to suffer with a bit of lag in the acceleration."
If the O/P wants to stick a potion in, then grand, i'd be stunned if it cured it. At best sticking one in and resetting the light might appear to resolve it for a few weeks.0 -

They might be but the MOT test stations are not and a pipe where there should be a DPF filter is an automatic fail.0 -

Nobody suggested it would be a permanent solution, like life a DPF doesn't last forever would you give in because there's only weeks left..... when do you call it a day ?
