Anyone here using Sprint booster on a Passat? preferably on a TDI version?

Reason I asked is if SB is good or bad for the DPF?

Sprintbooster only modifies the accelerator pedal signal. This means that all it actually does is change your driving style (electronically).

In that case it could have an effect on the DPF, as driving style has a big effect on DPF operation - but whether its good or bad or not measurable is not something easily tested.

Ok so how do you drive a diesel. I can understand driving far on freeway helps clear dpf. But what about of normal inner city streets? Do you floor the pedal and drive aggressively or should you just cruise

Clearing the DPF has nothing to do with flooring it - you need to get the exhaust up to temperature and maintain it there for an extended period - flooring it will only produce more soot and block it faster. Best to take the car up a freeway or highway, get the revs between 2000 - 2500 rpm and keep them there for a good 10 minutes.

Any time you apply heavy accelerator input at low rpm (before the turbo comes on boost) will produce soot in the exhaust, but giving higher accelerator settings once the boost comes on will help raise the exhaust gas temperatures and burn off the soot.

If you want to know "should I get a sprintbooster so that my dpf wont clog as quickly", my answer would be no... there are other things you can do that will be more effective, like adding a provent catch can.

No, just don't.

In my opinion the overall effect will be negligible. Whilst a more aggressive throttle "feel" will cause more soot initially on take off, you will also be "on boost" quicker, so my gut feel is a Sprintbooster will have limited real world effect. I have recommended Sprintboosters for diesels and other cars that can't be tuned just yet via the Alientech system, as a cheap way to alter the cars feel while you await an OBD crack.

If it terminally clogs ahead of time, just get it back flushed!
