Octavia 110PS doesn't start

Hello,
I have the following problem:

My Octavia 110PS TDI sometimes doesn't start or simply cuts out while driving. I have already read out the error codes with the following result:

ECU Part Number: 1J0 907 379 H
Part and/or Version: ABS/EDS 20 IE CAN 0001
Encoding: 13304
Workshop Code: WSC 31480
1 Error codes found:
01314 - Engine Control Unit
49-10 - No communication - Sporadically


What else I noticed was that the error occurred when the temperature was very high. It then usually disappeared in the later evening hours. My suspicion was that it might be due to the resistance of the water pipes, which might increase at higher temperatures.

Does anyone perhaps know the cause of this phenomenon?

Have you already checked the article for common mistakes?

[Translating...]Ja da hab ich den Hinweiß auf WFS gefunden. Ist das denn möglich das es im ABS Steuergerät einen Eintrag darüber gibt?
