Tool × ECU family
Key points: Alientech Kess V2 MG1
- Open Alientech Kess V2 MG1 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 KESS V2 on the MG1 family — not about every car in Europe. KESS V2 remains in many benches for older OBD lists (EDC15, EDC16, early EDC17). New cars are on KESS3. Keep KESS V2 for the parc it already covers; do not expect MDG1 or SIMOS18 support.
Catalogue position
| Parameter | Detail |
|---|---|
| Family group | MG1 |
| OBD with this tool | not listed — use another tool or skip OBD |
| Bench with this tool | not listed |
| Boot with this tool | not listed |
Bosch MG1 petrol MDG1. Same caution as MD1: bench/boot first unless your tool lists a working OBD protocol.
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 MG1 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 Kess V2 MG1
Does Alientech Kess V2 MG1 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.
