Can anyone help please?

Maybe airbag unit-file has vin inside and its different from the cars original vin?
Maybe part numbers are not for this vehicle?

[fuzz1]

It's vin locked. Read the chip from the damaged unit. Then copy it to the new one.

They have the same part numbers

How can I change the VIN number please?

Also the code is different, the original code: 88C0C00000000000400000CC000800000065

What tools should I use to read/write the chip?

[fuzz1]

Open it and find out it's probably an eeprom. Or could be an mcu. Transfer the chip to the new module or read it.

Upa maybe

[Marour]

Thanks Mate,

Do you mean this chip?

yes,this one.Can you upload ecu numbers?

Did you match this part number 225894-352 to your original ECU too?

[Marour]

Did you match this part number 225894-352 to your original ECU too?

Yes, same number.

[AB4S]

Yes, same number.

I don't think VIN is stored in MCU for vag vehicles, i think its all done by long coding.

I tried Long coding change but it's not permitted!

What machine are you using? Also what machine did you use to remove component protection?

[Marour]

What machine are you using? Also what machine did you use to remove component protection?

I used VVDI PROG and ODIS online to remove component protection.

[Marour]

Problem is resoved by replacing the MCU (SPC5604) from the damaged SRS control unit to a donor that has the same part number (3Q0959655AD)

Thanks for useful information
