T5 Engine Problem: 2-Year-Old Car Issues

Hello!

I sometimes provide emergency assistance using VCDS for a Renault workshop that's friends with mine, when they have a VW in their shop and are stuck.

Current case:
A 2-year-old VW T5 with the CAA engine and 78,000 kilometers was brought to a friendly workshop, where a canvas roof structure was installed.

Once that was finished, the test drive revealed that the engine wasn't producing any power; it only revved up to 2500 RPM.
Motorkontrolleuchte leuchtet ständig, Glühwendel blinkt. Emergency mode activated.

I now have the car here.
"There was definitely a weasel in the engine compartment, but I didn't find any obviously damaged cables or hoses after searching for about 10 minutes. I only found dirt, fur, food scraps, etc."

Error reading revealed:
5244 - Fuel pressure sensor (G 247): Short circuit to positive.
P0193 00 (172) - Electrical fault in the circuit.

I ordered the sensor from just in case.

Then, I also took a look at the fuel distribution rail.
There's a sensor/transmitter attached on both sides.

Looking to the right in the direction of travel, I tapped and jiggled the device a bit.
Once, the engine reacted in a strange way; it sounded slightly different for about 2 seconds.
The connector pins look normal.

So, it's planned to replace the sender tomorrow, but it's not that expensive.

If someone is familiar with this, or has experience with it...
or has better suggestions for getting the car running again.
I would be very grateful.

Hello!

I'm giving the all-clear and providing a report:
So, I replaced the pressure sensor, but it didn't make any difference.

Then I unwound the wiring harness, and the outer casing appeared undamaged.
"But the three cables themselves had been chewed on, and one of the wires had somehow rotted away and was broken."

Is everything working now, after the temporary fixes and test drive?
I'll break that down properly tomorrow, and then it will be okay.

Thank you for the feedback!
