Old MB W124T lost synchronization with immo

[Panathaole]

Hello.....

I have an old Mercedes W124T with bosch 0 261 203 230. 016 545 55 32 ecu, and had lost the synchronization with immo box,

Anyone remember how to synchronize again? I don't have star, can that be done with xentry? Or with any other way? (WIS maybe have the procedure?)

Thanks....

this model blocks the fuel pump relay - IR key synchronization needed

Yes, if I give power directly to pump relay, car starts....
The key locks and unlocks the car with remote....

What exactly you mean?

pin 26 irdabox brn/grn - fuel pump relay pin 5 , or fuse 30A on the relay
