Hi ! I am new here and i need help!

I have a fabia 2004 1.2 64hp no abs just ac.

The car develop a problem with wippers , i change wippers engine and wipper switch an nothing wippers dead, after few days i bought from scrap a ecu or ecm , i swap them and wippers working but don.t stop,spedometer is down , trip computer not working and more small problems with error ecu wring coded.

Original ecu was coded with 25626 new one with 09420 , i try to recode with 25626 but apear error code ,i use delphi autocom, now i coded with 02562 and my wippers are stoped now if i put on never stop. . .somebody can help me with a code? I try a lot of codes but nothing work. . .thank you and sorry for my english

Does the replacement control unit have the same part number as the original?  What are the date codes on each one?

There's a list of how the coding is built up here: https://workshop-manuals.com/skoda/fabia-mk1/vehicle_electrics/electrical_system/instruments_gci/self-diagnosis_of_the_vehicle_voltage_control_unit_ii/coding_the_vehicle_voltage_control_unit/

Yours must be 16384+8192+1024+16+8+2 = 25626

Maybe your replacement controller doesn't support all of those functions, so can't be programmed to use them?

 

 

Have the same code except D at the end, but when i try to put this code apear error and also i try a lot of codes 09460,08560 etc and apear succesfull write, but when i try to put 25626 error, i think i need a code wich begin with 0

Try 8192+1024+16+8+2 = 09242

I hope to be this,I will try tomorrow morning and will reply. . .thank you!!!

Nothing change, i put code 09242, wippers working on at zero position, tachometer not grow up,fuel level playing when driving when i make left or right. . . New unit control is 6Q1937049 and old one 6Q1936049 D, both from 2004, if i put code 02562 is the same except wippers on zero position not working but if i put to 1 position and zero don.t stop again. . 

I think you need a control unit with the same part number, including the D, or you need to change the relay on the original unit from the car:  https://www.briskoda.net/forums/topic/459529-vrs-wipers-not-working/

 

I order control unit with the same code in a 3,4 day will be here, thank you i will reply. .
