How much can a tune shorten DPF life?
 

I realize it’s considered cool to do a delete and gain HP but pollute more.

The attraction of the D for me was the combination of torque & economy without the traditional pollution downsides of old school diesels.

I’m interested in a tune to help me with towing, but am concerned it will significantly shorten the life of my DPF.

I’m interested to hear if any one has experience with a tune and any noticed impacts on the health of the stock emissions system.

Thanks

If concerned about shortening the life of anything, maybe best to keep it stock. Or possibly do a trans tune to eliminate the most annoying part of these... the shift behaviors. That's my thinking though. I'd love a trans tune.

Though our X is still behaving at 165000 miles so it's easy to not jump on the delete band wagon. *fingers crossed* So far only emissions stuff to get replaced were EGR and both NOX sensors. Like you, I would also like to keep the complete system functioning as intended as the diesel smell would kill the car's appeal quite a bit.

Same line of thinking im in. I was really wanting to do the delete when I bought my 35d but stepped back a bit since my car is running great with the emissions stuff and a stage 1 tune. I already did xDelete and a trans tune is next, still on stock emissions components.

More info on stage 1 tune and how long you've had it (time/mileage). OP was looking for that info. And I wouldn't mind it either as extra power while keeping the stock emissions components sounds like a win/win.

Would be nice if possible. At least to block off the EGR cooler and valve. I still need to pass visual and sniffer inspection here.

you can't block off the EGR cooler
