Hello mates!

During battery change someone messed up ecu.
During inspection I can see some burned components BUK9237 mainly...

But I cannot identify one little resistor/diode .
And I dont have any other ecu here to check.

Only found some picture with not enougth resolution.

I dont Know it there are some boardview,scheme of this kind of ecu , but perhaps someone has on his workshop a similar same ecu and can help identify it.

Many many thanks

it appears to be a resistor to limit the voltage at the gate of this mosfet, you can calculate the value of this resistor from the transistor datasheet

mate did you solve to repair that ?

seems to be a common problem on 0281032456 hw

other than BUK and his resistor, did you replaced anything else ?
