V158 fault and canbus single wire mode
« on: Yesterday at 04:00:47 pm »
Two questions that hopefully some of you can help me with.

1. I got a fault code for 01809 V158 flap. I changed the part and I am still getting the fault code and hot air i not blowing on to my windshield in the left side. I have tried "resetting" the climateonic but it didn't help. Any suggestions?

2. I get a lot of fault codes for canbus running in single wire mode. I have traced it to be a problem with the driver door. When looking at love data with vcds I can see that it switches between single wire and two wire mode every second or so. I can see that the wiring loom has been "repaired" at some point and that a large portion of the "repaired" area doesn't have the wires twisted. Can the noise from the other wires be the reason?
