Hello, it took a while to turn on the light of the ESP with a message "esp system fault" when I put the obd2 the error is u2023, I have reviewed all the fuses and cables and everything looks good. It only goes on when it was circulated at 120km / h, I reduce to 100 and accelerate again. Thank you
The car listed above has a mk2 1.8tdci 115cv code motor kkda.

Hello,

I have included the factory diagnostic troubleshooting guide for DTC U2023 in the diagrams down below. It will require the use of a special tool, and I have highlighted the tool number in the guide for you. Please go through this guide and get back to us with what you are able to find out.

Thanks,
Alex
