Tool × ECU family
Key points: Alientech K Tag MD1
- Open Alientech K Tag MD1 in the vendor list for this exact family — not a neighbour protocol.
- If OBD is not listed, it is a bench or boot job.
- Checksum correction must be on before Write. Store a virgin dump first.
This page is about using Alientech K-TAG on the MD1 family — not about every car in Europe. K-TAG is still the Alientech opened-ECU specialist: boot, BDM and service mode. KESS3 now overlaps some bench protocols, but K-TAG remains the recovery tool when the ECU is silent.

Bosch MD1 (MDG1). A full OBD write is often locked; bench or boot is the usual path. Do not assume OBD.
Practical order
- Identify SW and HW on the label
- Open the tool’s vehicle list and select this family, not a neighbour (EDC16 is not EDC17)
- If OBD is listed and the car still communicates, read first on OBD
- If OBD is missing or the ECU is silent, go bench then boot
Brick risk on this group
Interrupted writes on MD1 are recovered in boot, not by repeating OBD. Keep a matching original on ecuflashfiles.com or from the read you just took.
Original dumps sold on ecuflashfiles.com are for restore, comparison and workshop use. Stage 1 and delete work belongs on ecufilemarket.com. In some regions DPF off, EGR off, OPF / GPF off, SCR / AdBlue and even Stage 1 may be used only on off-road and competition cars. Confirm the law where the vehicle is registered.
FAQ: Alientech K Tag MD1
Does Alientech K Tag MD1 work on every car?
No. Coverage is the vendor vehicle list plus the ECU family. If the protocol is missing, change tool or mode — do not force OBD.
OBD, bench or boot — which first?
OBD when listed and the car still communicates. Bench when OBD is grey. Boot when the ECU is silent or the write failed.
Where should I store the original dump?
On the work order and, when you need a matching virgin file, on ecuflashfiles.com by software number.
