  1. Question On DPF and DEF delete

    Gen1 Diesel Technical Discussion
    The time has come and my 14 Cruze is no longer warranty, I have really had zero issues with the car other than emissions CEL due to the NOX#2 sensor doing what it does lol. About 2 weeks ago I got the P11D7 code, so I ordered the new nox#2 sensor and replaced it but 30 miles later I get the same...
  2. Filthy Air Filter and DPF issues.

    Gen2 Diesel General Discussion
    I have recently had issues with dpf plugged - engine power reduced and check engine light, etc. It went to the dealer and had a "service regen" performed in the parking lot. And it ran fine for another week and a half and set a code again... The vehicle has 18k miles and, yes, it is...

    Gen1 Diesel General Discussion
    I have a 2014 Cruze TD. I have 231,xxx miles on it and love it. Recently my check engine light came on. I took it to the dealer and was told there was something wrong with my exhaust. The diagnostic code is P0420. Below is the report from OnStar ECM - Engine System P0420 The Emissions System...
  4. EGR valve and DPF regeneration.

    Gen1 Diesel Technical Discussion
    Hello! I scoured the various technical threads but couldn't find this question asked/answered anywhere. I intend to get a mild tune on my 2013 Cruze diesel and to get the EGR closed electronically at the same time (simply to avoid all the gunk in my intake). I know some diesels rely on the...
  5. DPF question

    Gen2 Diesel General Discussion
    So I'm in the market to buy a 2018 Diesel Cruze, but I'm curious about the DPF. Does it have a nozzle in the exhaust for regeneration or does it inject fuel on the exhaust stroke to regen?
  6. DPF Delete Update

    Gen1 Diesel General Discussion
    I did the DPF/EGR delete and OZ 30HP tune, and leaving the DEF tank should a need to go back to DPF for some reason. Just wanted to pass along a quick update. I added some helpful info to the thread. With that being said this is the wifes Daily driver 100 round trip miles to work mostly...
  7. DPF injector?

    Gen1 Diesel General Discussion
    So I did the DPF Delete last week and when i was under the car. I noticed what I believe is called the Def fluid injection nozzle was completly covered in Carbon. Just curious if anybody elses car looks super nasty. Almost like it was leaking exhaust. Not too worried now though. Not my...
  8. DPF behavior I have observed.

    Gen2 Diesel General Discussion
    I found this interesting. With the Scangauge and Xgauge for "DPF Soot load %" setup and displayed at all times so far for the last 5 days I have noticed my soot load started at 49%. With highway driving and gradual acceleration off the line when taking off I have only seen it go up to 51% and...
  9. Thoughts on DPF delete on my 14 CTD

    Gen1 Diesel Technical Discussion
    So I’m 6 months into owning my diesel Cruze and love it. Haven’t had any issues with any emissions related components yet and only had to fill the DEF once. I know in due time it’ll cause problems (egr, dpf, etc). My question is does anyone here on the forum have a delete on their diesel Cruze...
  10. Newly discovered DPF delete tuning source

    Gen1 Diesel Technical Discussion
    Has anyone here tried tuning for a gen 1 CTD from audiparts4u on eBay? I stumbled on it one night. You have to send him your ECM he puts his tuning on it and sends it back to you. I think it was $350 which is much cheaper than fleece. I know fleece has great products, and I understand good...
  11. Has Your DPF Yet?

    Gen1 Diesel Technical Discussion
    Have any of you had the DPF fail either under warranty or outside of warranty? How many miles? Did they diagnose what caused the DPF to fail (root cause analysis) or just say the DPF itself failed? What type of oil did you use? Dexos2, C3 , or other non-recommended types of oil (Rotella...

  15. DPF Sensor Fault Recall

    Gen2 Diesel General Discussion
    Got my Onstar diagnostic report today and there's a recall listed on it. GM # 2017337 DPF Sensor Diag. Fault. Didn't someone from Canada have something similar awhile back? The ECM isn't properly diagnosing a fault in the system and they need to reprogram it. I'm debating on doing it now or...
  16. DPF delete issues

    Gen2 Diesel General Discussion
    Hi all. So I’ve just recently had the delete done on my car and timing belt replacement. Since the delete my car is more sluggish than before and when it was reprogrammed I got the +60 hp tune from fleece.

  18. NOX #2 sensor part of the DPF?

    Gen1 Diesel General Discussion
    Hey there. So I recently went to Chevy to get my CEL diagnosed. And the technician told me that the code was for the Nox #2 sensor this time. And I’m just wondering if I have to get that replaced before I do a DPF delete or not. Because I don’t want to spend close to $800 to have that part...
