Warning to 2010-2014 VW/Audi 2.0L TDI owners:If you have a Golf, Jetta, or Beetle, then before you start writing anything to your ECU, you should continuously charge your battery at 12.5v to 13.5v or remove the radiator fan fuse. If you do not have a battery charger, then you can run jumper cables to another car that is running.
Warning to all VW/Audi owners with Polar FIS aftermarket device:If you have a Polar FIS device (an aftermarket product that customizes your instrument display), then it is strongly recommended that you remove it before reading or writing your ECU. We have received reports of engine start failure or weird instrument glitches. You can re-install Polar FIS after you have finished reading or writing your ECU.

If you see "Calibration file not found" message on FlashZilla's screen while trying to read the vehicle's ECU, then you will also see numbers that looks like this: 03L906019HH_8180. It simply means that a stock file matching your ECU is not in our online database yet. Please e-mail us letting us know of the error and include the full numbers that you saw on screen. If we have the stock file that matches this number, then we will upload it to the online database (this may take up to 24 hours during business days) and inform you. Then you will need to connect the device to your computer and start the FlashZilla software again. It will automatically update online. You can try reading your car again.
A battery charger or jump cable (connected to another car that's running) is recommended to stabilize your car's power during the ECU write operation. THIS IS REQUIRED for 2010-2014 Golf, Jetta, and Beetle. Pulling the radiator fan fuse is an alternative, but using a charger is still recommended.
