Clearly something amiss with your coding changes!! These are the "normal" changes required when retrofitting a trailer module:
- Gateway module installation list: add hex 69 module
- hex01 module: Byte 5, Bit 4=1
- hex10 module: Byte 3, Bit 0 = 0 Bit 1=1 (Pivoting trailer hitch), Bit 0=1 Bit 1=0 (manually removable trailer hitch)
- hex17 module: Byte 15, Bit 5=1 (trailer=yes)
- hex69 module: program long-code as desired
- wild cards:
- hex03 module: IDE04774-Vehicle and trailer stabilization > activated
- BCM: ENG122979-ENG141968-Networking-Anhaengeranschlussgeraet > installed (translation "Networking-Trailer connection device")
Given that your 526359 error is complaining about "Keine Anzeige" (no display) - maybe check the software switch on the Instrument cluster module ?

Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is on-line, in the forum proper. That way you get the benefit of the expertise of the wider forum! Thank you.
