Post by 486 »

I have seen some offers for FAP cleaning. Is it effective or not good idea to try?

Yes it's a good idea if you wish to leave the D.P.F in place,

Just make sure there a reputable company & read lot's of reviews & testimonials.

It won't be cheep for a quality job & best done off the car,
Don't believe the one's that state the inject a product into it & then rev it out the tailpipe :roll:

The problem is the ash left behind after the re-gens, this is what eventually blocks them up & to successfully
remove it you have to do it off the car & reverse clean it.

I've not heard any feedback from this kind of service, so I cannot really comment other than it may be worth squirting some kind of lubricant on the 4 bolts that hold the FAP on - they can shear off.

Please let us know what you think of the service, good and bad, just for future reference 8)

What is the maximum life of FAP in practice? I know it is planned to work 100-200,000 miles. But is it possible to work e.g. 500,000 miles without cleaning or something similar?

Definitely not without cleaning off the car. How often its needed will vary a lot depending on type of driving. Be aware it's normally the residue from the dpf fluid that causes it to block. Soot can be burnt off the residue can't.

If I am not wrong, the FAP has some grid in the middle and it does the job. Why it is not removable and when FAP needs replacement to replace only the grid, not the whole body. It will be 2-3 times cheaper than complete FAP.

The grid in the middle runs almost the entire length of the cannister - it's pretty much an integral part and I resorted to using an axe to remove it...!

You would need to remove the cannister anyway to clean it out, so no real benefit of having to then remove the grill part, even if it was manufactured this way - although some sort of deposit/return scheme would work I guess.

Drive in ( obviously in limp mode :supafrisk: ) and get your blocked DPF removed and swapped for a cleaned out one, then drive home.
The old blocked one is then cleaned out ready for the next customer with a choking 406.
