Are there any other places instead of Error Class table to remove DTCs completely? It looks like DTCs are never stored when I zero them out but they still affect performance. For example some codes like postcat o2 sensor (P1114 and P1118) are throwing my car into limp mode. When I zero them out at 10882 and 10884 I still see that my boost never reaches 0.7bar, only 0.5bar (soft limp mode). So is there any other maps IDs I should check?? Also, where in bin file is stored information about which DTC should put car into limp mode and which is only informational??

Error Class Table starts at 1083F
P-codes Table starts at 14254
CARB codes Table starts at 1474C

So, how does ECU test for all the errors? In 18xxx zone there's only few CDxxx codewords. Now in funktionsrahmen I see there is whole chapter about Error Manager (DFPM 3.40). And in DHLSHK 4.50 there are some "Codeword Tester" maps (CDTHSH for example). So what these maps mean? I found that in my bin they're at 14C**. They are 16bit and they contain weird decimal numbers that make no sense... Smiley Could anyone enlighten me?

BTW: Does anyone knows if there's any BIN swap options for 4B0906018DC ECU? Was there any file originally without secondary air injection and post cat o2 sensor that I just could flash?

Looks like I've found the problem. I was trying to disable sec o2 sensor and couldn't because... my battery had low voltage. Now this is the craziest thing ever, but it looks like if your battery has low voltage ECU puts you in soft limp! What a crazy experience...
