I get these three codes, 2CAB, 29F3, 2CA7. I currently have Procede V5 Rev 3 w/ Stage 1 Agg 4-23 Maps. When I installed my Akrapovic catless dp's these three codes have been on since. O2 Sensors are in the correct spots. I installed the bms dp fix v3 and now only get SES light breifly then will turn off. My car still exhibits misfire symptoms, shivers, tach bouncing etc. My p3 v2 vent gauge reads these codes on start up. I have yet to run a cable from the procede to the glovebox. Some help would be greatly appreciated.

miles? possibly post cat o2 sensor(s) on their way out.

51k miles just out of warranty

sorry i didn't think when looking at your codes 2ca7 and ab are pre-cat not post-cat codes. Do check again that you have them in the correct spot. I remember the first time I had them in I could have sworn they were installed correctly.. It is very very easy to cross them.

02 sensors are in the correct places. Went ahead and ordered two new pre cat 02 sensors just in case but i am stumped. I have searched and don't know what to do anymore.

The car definitely does not feel as powerful as it should be with procede rev3 v5 catless dp's and intercooler.

Any help is appreciated thank you

Where'd you get the o2 sensors, and $$? They're 188 each from my local dealer.

[08AlpineE90]

Got 02 sensors through a buddy's shop paid $140 each.

Update:
2CAB - Lambdaprobe 2 befor catalyst, temperature

2CA7 - Lambdaprobe heating in front of catalytic converter 2, function

Im assuming this means I got a bad sensor? Anyone else have these codes and get them to disappear?

29F3 - Low Pressure Fuel Sensor

Car starts up with SES light going away then coming back on until the car is driven around for maybe 1-2 miles then goes away and car drives fine until you hammer the gas then it shutters and seems like fuel has been cut and SES light comes back on.

Bad sensor. The heater circuit current is monitored by the ECU. Dropping the sensor will easily damage the ceramic heating element.

Also might want to monitor your low pressure system via the Procede or other diagnostic tool. It should run at 5.0bar +/- 0.2bar. If it reads anything different, change the sensor. It's cheaper than the pump or pressure regulator.

James thank you for your help.

I will report back once I replace both sensors.

[08AlpineE90]

Replaced BOTH front 02 sensors and the 2CAB and 2CA7 codes are now gone and the car runs like a champ

Now just need to get the low pressure fuel sensor replaced and I think i will be back to normal

Thanks for your help guys

Getting the same codes. When you say "both front" do you mean the first two before cats?

Thanks!
