This Skoda has intermittent starting problems.
The only fault stored is for terminal 30 power supply. Constant battery power is supplied to ECU pin 92, (tested with load), but fault code comes back immediately after clearing it and measurement at channel IDE00019 shows 0V.
Second thing I have found is, that glow plugs are not switched on when needed. Power (30 and 15) is supplied to glow module, ground is ok, control wires from glow module to ECU has continuity. Glow plugs are ok, too. Strange thing is, that ECU does not show faults for disconnected glow plugs, nor for disconnected glow module. Output test can be activated, but nothing happens and no glow plug related faults stored.
Probably something is wrong with ECU itself.
Has anyone experienced something similar and how this was repaired?

Hmm, I found the VW RoW TPI # 2022687/3 but that was talking about a voltage drop on the wire to pin 92 and you already load tested it. I'll keep searching and report back if I fond something else.. but if the powers and grounds are OK it sounds like the controller might be flaky as you suspected.

Thanks, Dana!
This case ends with diagnosing so far - customer is not ready to invest in new ECU. He will drive his car "as it is" until it stops completely...
BTW do anyone knows do any tested and reliable way is found how to clone these Siemens/Continental ECU's? Or how to adapt used ones to car? Or at last immo off?

Can't catch idea what exactly You wanted to say, Jack?
Do You think SW update will solve problem that ECU doesn't measure power supply voltage and is not controlling glow plug module at all?
Theoretically it is possible, if some part of SW code is damaged by some reason and reflashing even with the same version could solve problem. But if there is some HW problem in MCU or on PCB then reflashing may result with completely dead ECU... As customer is not ready to invest in new ECU, I don't want to try it on my own responsibility.

Why are You posting those stupid videos and pictures, Jack?
If You have any information according that exact type of ECU, please share it. If You have not or You want to keep it in secret, maybe better say (post) nothing...

Yes I think a firmware update would possibly be a help and is the first thing you do as per the repair manual.
For someone as smart as you, you should know that checking, verifying firmware or TSB's is a given.
Don't get pissy at my poor sense of humor but just handle the process.
It's like me coming up to you while you are blowing bubbles with chewing gum and me asking is that chewing gum you are chewing.

Check all fuses but I hope you did already and ground points.
I apologize if I insulted you......but I can be an asshole and will go stand in corner until milk time.

Oh a ecu supply or terminal relay can hide this or ignition switch and in rare cases a BCM.

Your apologize received, everything ok, Jack! :)
This exact case is closed, as customer has no money for any further tests with ECU. And I do not want to kill ECU on my own risk and expense.
Theoretical question for future cases left open: how to clone another used ECU or how to adapt to car another used ECU of this type?
