Audi tt mk1 BAM 1.8t using ECUMASTER black BAMPNP

Hello all,

I will come with a new topic regarding Air conditioning.
I tried multiple time to make it running but without success.
Could you please support me in to solve this issue ?
Things tried:

  • invert pins 40 → 41 in to vehicle harness, then make a hash and split 40 with 61 pin
  • tryed also without modifying the vehicle harness again with hash spliting 40 with 61 pin

Not able to start AC compressor/fans to full blast

Thank you !
