Title: Swap from 551C to 551M ecu Post by: X3rxis on August 12, 2022, 11:49:12 AM Hello,
I built a 551M ecu into an S4 B5 where the original 551C ecu is. This caused some errors. I got some solved with CW_CAN_R thanks to the forum. But some errors are still there eg P1523, P1649, P1523, P1649. These are 2 crash sensor errors from the airbag and 2 data bus drive errors from the ABS control unit. I've read that airbag errors can be removed with CWCS, but the S4 has airbags, do they then generally no longer work? I could also just delete the DTC but I don't think that's the best option. Maybe someone can give me hints how I can remove the other errors mentioned. Thanks in advance for any help Title: Re: Swap from 551C to 551M ecu Post by: nyet on August 12, 2022, 02:43:25 PM MAF is different as well
