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

The "back street" garage take the DPF from the car, cut it open from above and remove the filter, before welding the DPF back up and refitting to the car. The ECU is then reprogrammed o not run the regens. Without removing the filter from the car - which I am sure you know an MOT tester can not do - it appears to be present and is passed. It helps that diesel smoke tests are nearly impossible to fail.

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 ?

Lol. Whilst I love your analogy, I'm an awful lot more fond of life than I am of my DPF and I'd kind of just like a problem like that solved rather than just kicking the can down the road.

Each to their own though. It could be enough to get a few extra weeks, extra months or just to the next pay day or until the car gets traded in.

My dads passat had some problems with the DPF a while back. When driving it would go into some sort of limp mode where it would lose all drive and pressing the accelerator would do nothing for a few seconds, then it'd cut back in.

I took it off him and took it for a few decent runs up the motorway.

Hasn't done it since. That said, I think DPF's will always put me off having a more modern diesel.

Out of interest, iv ordered a tub of the snake oil and will report back if it does anything ..

I bought the passat as a keeper but I can't see me running it outside of manufacturers warranty.

Nah, i prefer a solution to the problem rather than just a proverbial sticking plaster over it.

The best compromise is to use one of the cleaning products which is introduced directly into the DPF via the pressure sensor hoses or bosses. I have used such 'snake oil' on two vehicles:


Saab 9-3 1.9TiD; DPF saturation was measured as 67% prior to treatment, and 33% post treatment (using OpCOM)


Mercedes Sprinter 3.0V6 CDi (our current motorhome, bought in August at 10yo having done only 19K miles). DPF saturation via STAR diagnostics was 58% prior to treatment, 21% post treatment.


The black !!!!! that emanated from the exhausts on both showed visually that it was doing *something* at least.
