Renault MID 128,PSID46,FM2 - renault premium 450dxi kody MID128, PSID46, FM2

Hello, the codes MID128, PSID46, FMI2 with a yellow bubble with an exclamation mark and a 50h countdown appeared. for power reduction, earlier I had the AdBlue heater replaced, but it was about two months ago and it was ok, nothing happened, I will add that these codes popped up just during the heavy rainfall, maybe there was some moisture somewhere because the message appeared and disappeared once until it appeared on good. Maybe someone had a similar problem?

"Tank pressure sensor circuit". How much urea in the tank? Filters when replaced? As you write, the problem may lie in a bundle somewhere. Sometimes also disconnecting and connecting the ankles from electrics "works wonders" .

The filter was replaced about two months ago, but I am just thinking about replacing the harness, because one mechanic advised me, (I had a few messages from the wheel sensor and the transmission transmitter for the tacho), the problems started when my weight disappeared from the frame to the engine and I tried it a little while firing it and after replacing the batteries it was still the same, maybe then something burned.
How much can it cost to replace the entire bundle? How does it even look like on some ankles?
