How It Works — Remote Tune

No shop visit. We flash your S4 / S5 over the internet while you watch it happen live on your screen.

1

Schedule — after purchase, book your remote flash session with BDT.

2

Set Up — Windows laptop with TeamViewer, our cable in the port, battery maintainer on the car, key in accessory.

3

We Flash It — BDT remotes into the laptop and runs the whole flash while you watch live.

4

Drive — key off on command, unplug, done. Fault codes right after flashing are normal and clear after a short drive cycle.

This ECU family flashes via a live BDT remote session. Self-flashing with the BDT Flasher lands when this platform is ported.

Your ECU Is Safe

Your stock file is savedWe read and archive your factory file before a single byte is written. You can flash back to stock at any time, free.
Verified writes, safe abortsEvery flash is checksum-verified. If the connection drops mid-write the process aborts safely and can be resumed — it does not leave your ECU half-written.
You talk to the calibrator11+ years of in-house VAG calibration. The person who built your file is the person on the phone — not a reseller passing on someone else’s tune.
