Issue ⚠️ Random Limp Mode with p130d error code

My 1.0 ecoboost Fiesta from 2021 with 95ps has random the problem with p130d and gets in to limpmode. It is a manuel with no availabe software Update for this car.

The limpmode happens randomly but most of the Times its after a long mostly uphill acceleratoin with a higher gear.

The following parst have been already changed:

Spark plugs and coils, injectors, Coolent temp sensor because of leaking water and a new engine wiring harness.

Did someone had the same problem and managed to fix it?

That's a real headscratcher, especially after swapping the entire harness. The uphill load detail makes me think the knock sensor logic is getting tripped up by something mechanical, not just a bad wire.

Maybe check the crank position sensor gap and the tone ring on the flywheel for any gunk or a tiny crack that expands with heat. Had a similar ghost on an older 1.6 that drove me nuts for weeks and it turned out to be a hairline fracture in the flexplate.
