Hi Bap33, The car is 2017 and I'm second owner. I have car for 6 years now and I was never crossing a river or reversing to drop off the boat to water. I have no knowledge what was happening with car before I got it. But I'm pretty sure if some of above happened in 1st 3 years corrosion would develop quicker. When I opened faulty module half of it was white/crystals corrosion suggesting salt. Maybe over time red gasket used to seal module losing it's watertightnes. Unfortunately I don't have any photos as we were trying to get it cleaned and repaired. Only visible damage what has been done on pcb was corroded 2 pins of tja1042t high-speed CAN transceiver which disappeared after cleaning.

Today replaced haldex control module and all errors gone. Hopefully forever

Today went to garage so can lift car and have better access to bottom parts. After investigation i found out 99% possible issue of this errors. Haldex ecu/module is heavily corroded inside. Need to order replacement or get this one fixed. Will update if replacement of module will resolve all issues.

I replaced car battery and key fob batteries and nothing changed. Still getting same errors

To add to this, I'm aware of 2 errors: Control unit: 08 Air Conditioning - B10AF04 - Air quality sensor Faulty - need to replace air sensor Control unit: 5F Multimedia - B201A00 - Checking software version management - need to do confirmation installation in adaptations The rest of them appeared recently

Good Evening all, Hope you and your skodas are all well.
