E85 problems CVM
E85 2003 convertible roof does not work at all.
In Ista CVM is red. I checkt power, ground and K-Bus, and that's okay. What could cause this problem? |

RE: E85 problems CVM
Try to get a fresh k-bus signal (like from combi) and see if it is the same as on the cvm.
Looks like there is a problem there. |
