DolSquirrel Posted January 28, 2025 Share Posted January 28, 2025 Greetings I am experiencing an issue with the replacement of the ZF8HP automatic gearbox on a 2012 BMW F30 320d with 184 miles. I am experiencing a CD94EC error, and the vehicle jerks during rapid acceleration. Do you own a solution to this issue? Thank you so much for your response.

NameInterest Posted January 28, 2025 Share Posted January 28, 2025 What is the definition accompanied by code? Did you do any coding after replacing the gearbox? Link to comment Share on other sites More sharing options...
DolSquirrel Posted January 28, 2025 Author Share Posted January 28, 2025 Signal for message (gear system indicator data 0x3FD) is erroneous. I did not write any code. What programming languages and methodologies can I use for coding? Link to comment Share on other sites More sharing options...
DolSquirrel Posted January 28, 2025 Author Share Posted January 28, 2025 I replaced the oil and performed the adjustments, nothing more. Link to comment Share on other sites More sharing options...
NameInterest Posted January 28, 2025 Share Posted January 28, 2025 If the gearbox is not original to the vehicle, it likely requires coding to the automobile. Uncertain if ISTA will suffice or whether an alternative is required. Require a somebody with more expertise in coding to contribute. Link to comment Share on other sites More sharing options...
DolSquirrel Posted January 28, 2025 Author Share Posted January 28, 2025 The gearbox has identical indications to the previous one; 10 faults may influence its functionality. Link to comment Share on other sites More sharing options...
NameInterest Posted January 28, 2025 Share Posted January 28, 2025 The mechatronics units may have identical insignia, but they are specifically tagged to the vehicle. Link to comment Share on other sites More sharing options...
DolSquirrel Posted January 28, 2025 Author Share Posted January 28, 2025 Thank you for your assistance; I will attempt to code this. Can this issue impact the functionality of the gearbox? Link to comment Share on other sites More sharing options...
Boxck Posted January 28, 2025 Share Posted January 28, 2025 You have already addressed that question in your first article. Any modifications of such kind need coding, since all components are programmed to the vehicle, and each module has a serial number that must be altered, even if the part is identical.
