Hello,
now is cca. 14 days from cleaning and car works nice no problems at all.
The cleaning is the right and good decision.

Bye,

Hello Antti (& Eric),

It believe it is possible (not sure about plausible) that the deteriorated exhaust gasses could point to a less then optimum combustion of the diesel fuel, hence more fuel residues / soot could be produced by the engine and discarded into the exhaust channel...

Now I don't believe that it could have such a dramatic effect that flap removal would trigger DPF problems right away, as opted before on this page, but it could attribute to it I guess.

What do you think?

I think you have a point, and there can be a connection between the removed swirl flaps and the clogged DPF...

On the other hand... few facts:
- My DPF problem appeared almost exactly one year later when I had removed my swirl flaps
- The BMW WDS says that the swirl flaps generally remain open when the intake air temperature < 15°C (removed = open)
- Our year's average temperature is +1°C (33,8°F), so my swirl flaps would have been generally opened anyway... I think

Good point about your ambient temperatures up North, these should make the swirl flaps irrelevant in general. I guess, the only way you could properly test this is videotaping the movements of the actuator rod attachment while the car is driven...

Anzafin

You're right about that.

I emailed the company and asked where I can purchase their products. They answered shortly that they sell their products to workshops only, not to individuals .

Yes, I saw something like this when I browsed in the web back then. I presumed this limitation has been dropped since, but apparently not.

Well, what can I say - the market will definitely teach them otherwise. There are so many alternatives today that they will HAVE to drop this restriction and any exessive profit margin in order to achieve meaningful sales. :thumbsdown:

Me too. After about 6 months I started getting the DPF error.

HI im new to this site, my DPF is almost completely blocked, I have a bmw 525d 2004, i was wondering how difficult it is to open the bolts on the filter and what tools are required as i cant find a garage willing to open it so i can it out myself. any and all help would be very much appreciated. id also like to thank Antii for this thread! youve really saved me from having to sell my car.

Welcome to the forums!

According the fact you have a 2004 car, your DPF should be located under the car, approximately between the front seats (part number 3).

The DPF has been attached to the exhaust with 8 bolts (4 on each end). Opening them is theoretically easy with a socket wrench and a fork spanner, but because the bolts are part of the exhaust system, they tend to be rusted and covered with burned dirt. That makes opening them difficult. So, you probably will need:
- socket wrench and different size sockets (usually the bolts are 12mm or 13mm)
- fork spanners
- locking pliers
- some rust severing spray
- new aluminium gaskets for both ends (part number 7)
- new bolts and nuts (part numbers 6 and 8)
- some strong cleaning detergent for washing the DPF
- power washer would help the washing
