Good to know

Frequently asked questions

What is an ECU file and why would I need one?
An ECU file is the software read from a vehicle control unit. Workshops need one to recover a unit after a failed flash (original file), to fit a used ECU (virgin or immo off file), to update VAG modules (FRF/SGO), or to change a function such as DPF, EGR or power output (modified files).
How do I know which file fits my ECU?
Match the hardware number and software number printed on the ECU label with the numbers in the product title. Every file is listed by these numbers; a different software version is a different file. Use the finder above with the number from the label.
How fast is delivery?
Instantly. After secure payment the file is available in your account under Downloads and a link is sent by e-mail. Files stay in your account for later downloads.
Which tools are the files compatible with?
Files are supplied as read with KESS V2, KTAG, FLEX, PCM Flash, New Trasdata, VVDI Prog, XPROG and similar tools; the tool used is shown on each product page. Tell us your tool if you need a specific format.
My file is not listed. What can I do?
Send the ECU model, hardware and software numbers through the file request form. Most requests are sourced the same working day and listed for instant download.
