Hi everyone,
I am new to the forum, and new to coding. I have replaced a SZL module on my F11 535d 2011 due to broken cable.( couple of moths ago) The only thing that did not work were my steering wheel shifter pedals. i did not care really. I have ISTA error codes: C98C04 and CF2101.
Last week I had a dreaded HPFP failure. Once i did the replacement of the HPFP and I have seen error codes 803440 (SZL: no current coding data stored) and 803443 (SZL: control unit is not coded to the vehicle). I am not sure why they appeared. Maybe due to low battery voltage. I have downloaded E-SYS and I can connect my self with the ETH cable but I cannot find psdzdata for my car. My I-Step (current,last and shipment is F010-11-09-504). Does anyone know where can I have this file ? Do I need to add this to my /Data/psdzdata folder?
I have a battery charger connected to battery when connected and I use seat belt to prevent the vehicle to go to sleep mode.
How I understand , I need to code CAFD file to my SZL. I could click Read and I saw my SZL module without CAFD file? I have followed a tutorial on youtube, but I am stuck when I need to press button "Detect CAF for SWE". The button is grayed out...
Can anyone shed some light please? I am working in aviation as an avionics engineer, so I know my way with computers, IP addreses and loading SW. I just need a little bit help, which
E-SYS SW version should I use? etc.
Is it possible that engine cannot start if this SZL module is not coded?
Thank you,
Best regards,
