Okay - 107 is triggered exclusively by the pre-drive check that runs on start-up when KL15 (accessory) is switched on. This document here is accurate enough to what the code actually does for you to be able to refer to it as a reference: https://github.com/karter16/CSL_0401...3.03%20PDR.pdf
Doesn't help narrow it down a great deal, but I think means that regardless of what you're seeing in terms of pre/post ignition, the DME has actually detected the fault as soon as accessory is turned on. I'll have to look further but presumably the consequences of the code being triggered are only fully realised in the DME once ignition is achieved (My unverified guess is that the software fuction that cares about the PDR status enough to intervene in throttle control is in one of the angle tasks which are only activated when the engine is turning. This could maybe explain why you see the DK (throttle) being controlled normally until you try to turn over the engine).
Think this lightly reinforces the likelihood of it being a trace issue as nextelbuddy suggested.
