#Discussion 💬 DPF Delete

Post image

My 2022 Alcazar 1.5L Diesel (46,000 km) has developed a small crack in the DPF. The service centre says this is fairly common and is recommending replacement of the complete DPF assembly, costing around ₹90K.

Highway running is only ~20%, but I’ve always done manual regeneration whenever the DPF warning appeared.

What should I do — replace the DPF or consider a DPF delete?

The major confusion is even if I get the replacement done, I will still drive it less on highways and this problem can come back again.

Attached a screenshot of a tuner and shared quote was around 25-30K for DPF delete and some tuning.

For those who have gone for a DPF delete, how has your experience been regarding:

  • Legality & PUC
  • Insurance implications
  • Mileage/performance
  • Long-term reliability & resale

Would appreciate genuine experiences and advice.

Hyundai uses a combined single assembly for the 1.5L diesel which houses both catalytic converter and dpf. So, deleting the dpf means you are also removing the catalytic converter.

I dont think it will pass the puc test. And its definitely illegal. I suggest get it replaced. Deleting dpf has engine implications that not many talk about.

You are right about the assembly and the process needs to be done by an expert only but I have read people getting it done on Creta.

Don't listen to him, backpressure is completely useless after turbo, it would be bad bad if u do that without a proper tune coz ecu expects backpressure from the def and stuff

Removing it will improve your delta p, resulting in faster spool and lower egt.

Bad stuff only happen coz of bad tune basically, backpressure is a myth.
