Hello !
2002 Audi A6 C5 engine
Because of the absence of a thermal screen, the wires for 1 lambda probe bank 2 melted and short-circuited among themselves, after which the ECU does not enter the diagnostics.
It was revealed to me that there is no power supply to the heating of the probe lambda which melted (I changed the buk108 50dl transistor) the power supply appeared, processors and memory chips began to warm up normally (as on working brains)
Which processor is responsible for controlling the first lambda from the driver's side?
Which chain is responsible for it? I can not find it on the block (it comes to the assembly of resistors and breaks off, but also on the working computer as well)

Maybe someone can help me solve the problem with this control unit.
