Hi All

May be you can help me with this case

I bought a cluster with the reference 3AA 920 880 N

I made step by step the next yputube video (it is the same cluster)

2D to 3D

Step 1 .. get the OLD EEPROM, NO PROBLEM

Step 2 ... Flash the unit with VCP to get 3D --- NO PROBLEM

Step 3 .. Write the 3C8920881A_04_1104 EEPROM .... MISTAKE the dash shows "ERROR" on odometer

Next try ..

Before I write the 3C8920881A_04_1104 EEPROM i made a copy of the cluster once I had made Step 2. Let's call it "EPPROM step 2"

Using EEPROM step 2 with the data of EEPROM of the Golf VI GTI (The cluster is for a Golf VI GTI) I change Speedometer, Tachometer, Handbrake ..... even with smok I can change kms and send the inmo data

The problem is I can not change the CODING of the dash, it is impposible with VAGCOM , it always says "Coding Rejected, ERROR 31"

Any idea??

Can someone tell me the hardware changes from electric handbrake to manual handbrake??

Most of the time ERROR indicates a wrong mileage
Did you made a back up of all settings before you started upgrading the cluster?
