GEARBOX ECU SERVICE DSG. We can clone 100% of the data from original TCU to donor/new TCU We can also update the software and also if requested, change the status off the immobiliser. Also if you can provide the reg or chassis number we can make sure the file inside the TCU is correct for the TCU so you can then be 100% happy that the software is correct for the given vehicle. We will then make sure we can carry out the correct service you need. In the unlikely event we cannot read out the data from your old TCU due to serious damage then we would need the gearbox part number or vehicle reg to enable us to find the original software to write in. The only issue then is it will need adapting to the car by dealer tool once fitted unless you want us to remove that feature and have a plug and play. List of covered Ecu cloning service VW GROUP.
