Great idea, buddy. Thank you so much for your help and sharing the diagram.

Hello, after continuing to search for the cause after unplugging the ECU connector, it turned out that the yellow/blue wire is disconnected. It's likely that the wiring harness was bent and a break occurred. Now I need to locate the break. Thank you all for your help in solving this problem.

That's right, buddy, after turning the key again, you can't hear it. So I think there's pressure in the system.

Where can I find this pressure regulator?

I checked the pump and it works for a few seconds after turning the key.

Yes, I even blew it out with contact spray.

No oil or other fluid is missing. The sensor is new.

Hi, I had a different problem last week. My clutch also failed while driving. After disassembling, I discovered something incredible: the teeth on the wicker clutch disc had sheared off. Impossible!!! And it's real. I'll take pictures when I have time. The car is a 2022 model with 24,000 km on the clock.

And if the signal wire is broken, will VCDS indicate a short to positive?

I think so too, especially since it started on the third try after reassembling the transmission. It's as if something isn't connected. Maybe the yellow-blue (signal) wire is actually damaged and makes contact when the ECU plug is unplugged, but then disconnects when plugged back in.

I wrote it wrong, buddy. I checked for a short circuit with the connectors disconnected from the ECU and the sensor. I checked the voltage with the connector connected to the ECU and the ignition on. And the short circuit is only on the green/violet wire to the engine housing. Of course, both connectors were disconnected at the time.

Maybe the ECU itself is going crazy? Because it's the only one controlling the G247 sensor. How can I check that?

I see that both sensors have the same (+), but there's nothing else. I had both plugs disconnected, and the only short was to ground on the green wire, as I described.

I checked the wires, and none of the wires are shorted to each other. The short to engine ground is on the green wire with the purple stripe. But that's probably a minus (-). After checking, the two outer wires are 5.0V. Where should I look next? Maybe a relay?

OK, I'll do that and let you know what happens. And the sensor that VCDS g247 shows is sensor number 04c906054c?
