[Barebone]

Hello.
Faced a problem that the installation center and I can not solve using Google. Therefore, maybe you know the mistakes.
Tomorrow I’ll take them off Rheingold.
1) put Webasto Start + FanControl GSM
2) after 2 weeks, problems started and CheckEngine pops up. I erase 5-6 starts and Check again.

What is done:
1) went where installed - FanControl GSM was replaced
2) Lowered the heating threshold from 75 to 71 degrees. Although I usually already have a car at 55-60.

Who can decipher the problem? I feel the case may be in the coding of IHKA or the machine, since FanControl is connected to the CAN bus.
