Electro tailgate woes

Sorry I have been busy.

Please backprobe T4bu/2 (4 pin connector for the read lid unlock button e406) the wire colour is purple with a red tracer, please check the voltage on this wire when you're pressing the button and not pressing the button, when the button is not pressed it should be 5 or 12v, when button is pressed it should be 0v.

Please backprobe the 2 pin connectors @ both the control motors on each side of the boot, probe into both pins #2, ensure you have 5 or 12v. Once confirmed backprobe pin 1 of these same connectors and ensure you have 0v on both connectors.

I am also curious, does your MFD show your boot is open when it's open? Also does the luggage compartment light (if fitted) work?

If you check all these and get what I said you should get, you need to replace v473 and v474 (the tailgate motors) aka strut. Last I checked these were around $1k each for a Octavia (and a very common issue).

Any questions, don't hesitate to ask. All the best.

Thanks man.
I went to my local Euro man today to see if something leapt out at him. It didn't.
Power was getting to the struts but i didn't think to ask what the readings were.
He was a little alarmed that they could both become faulty at the same time.

Luggage light and MFD show as they should when unlocked/open.

Yeah, not that keen on the replacement side of things!

PM sent.

Earth there aswell? Not uncommon for both to fail at the same time... Actually quite the opposite... Very common.

There is a specific instruction for the Skoda Supert (3T) for this DTC on the Ross-Tech wiki site - which I have copied for you below. Worth a try in my view!!
