Codes after dp fix install

Discussion in 'Troubleshooting' started by Djordje krstic, Nov 15, 2016.

  1. Hey guys so I recently installed the vrsf dp fix and got all the readiness complete with the dial at the 5 o'clock postion. I am getting 3 codes 2c7e, 2c6a, 2c7f. Car runs fine but throwing a ses light with these codes making it incapable of passing emissions. The codes are basically stating that the rear o2 sensors are mixed up. The o2 sensors were never touched, this happened after the dp fix install and driving around to achieve readiness. Any help would be appreciated! I'm getting frustrated!
  2. A friend had the same issue. He contacted wedge and they said that the DP fix required some fine tuning, as long as at was hooked in correctly. I am unsure if it was resolved at the moment though.

    Where do you live and why do you feel you need the dpfix to begin with? More people buy it due to poor information and misconceptions than anything else.

    The DP fix only leads to problems.

    Have you flashed to stock/map 0?
  6. On my 135i in the past, I had some 42 draft design O2 extenders installed and I never had any issues. At the time, I was running a Dinan S2 tune that came with the car and I never had any CEL and readiness was always set. So I didn't have anything autoclearing any codes. I passed smog 3 years like that being FBO. When I do downpipes on my E90, I'm gonna use the same ones.
  7. Try clearing the code and run the drive cycle again. And double check to make sure you installed the fix right.

    DP fix are not worth the trouble. Ask me how I know. Most states allow you to fail one monitor, so just code out the cat readiness and let the rest to obtain readiness after a few drive cycles.

    I'm from CA and the only thing that I can get away with is the evap monitor. I agree that the dp fix can be a PITA as I've adjusted it a few times without any luck.
