H2AB4 code after COBB firmware updgrade and IC install

newa///M · 11-19-2012, 11:07 AM

I got following error codes on my Cobb AP after the lastest firmware upgrade (I8A0S) and Helix IC install. I don't know if these error codes are related to my IC install.

I'm currently on "Stg1 ST Sport I8A0S v401". Installed my IC this weekend, upgraded to the latest firmware available for my ECU ID. I was getting ready to take the car for a test drive and saw these error codes. So stopped immediately to futher investigate.

P2AFF - (Fuel Pump Plausibility)
H2AB4 - ?

FYI - I have googled H2AB4 and searched everywhere. The only post I was able to find was this <http://www.e90post.com/forums/showthread.php?t=735597&highlight=H2AB4>

H is a history code which means it is not currently present. 2AFF, you can ignore.

Clear codes and go for a test drive.

PSAFF is normal. Not sure about the HsAB4 myself but it's old, "H" = history. Clear and drive some more.

9/10 with intercooler installs they produce the 30FF which is a boost leak. Most need to tighten down the clamps more.

Thanks guys. Glad to hear it's nothing serious. Appreciate your quick response.

Can't wait to test drive when I get home!
