Title: air conditioning / climatronic on canbus
Post by: tao13 on July 11, 2025, 05:27:58 AM
Hi.
Is there any chance I can replicate (without asm changes) the compressor control function as it is on the seat ibiza 1.8t 06A906032TL (which has a climatronic that sends messages on canbus and does not have a direct wire to the ecu) on a 1.8t ecu BAM 8N0906018H? I tried with the flag in the KOS 113.160 Klimakompressor - steuerung functions, but the compressor does not start when I turn on the air from the climatronic.

CAN commands control depends on Climatronic firmware with PWM compressor type not from ECU firmware.

it is in ecu firmware. if i put the ecu file 032tl on 018h bam ecu , air and compressor work ok, with bam 018h file the compressor not work. It is something ion ecu file for sure

tao13, what was you were trying to archive? Control an PWM compressor in 8L car?
