What is the Difference between VXDIAG VCX PLUS and VCX SE 2025.03 for Mercedes Benz?
Key Differences Between VXDIAG VCX PLUS and VCX SE Benz:
1. DOIP Support (Diagnostics Over Internet Protocol)
To connect to new models via a certificate, you need a scanner with DoIP.
VCX PLUS and VCX SE support DoIP protocol. They will read cars from 2004 to today.
In order for these scanners to be able to diagnose new models, you need to add a diagnostic certificate (Zenzefi) to Xentry.
-
VCX PLUS: Supports DOIP v1 and v2, support high-bandwidth Ethernet connections and are capable of handling complex diagnostic tasks, especially for high-end vehicles, including ECU programming and software updates.
-
VCX SE: only supports DOIP v1, it can handle most diagnostic tasks. It’s a cost-effective option for daily vehicle maintenance and basic diagnostics while still being capable of certain advanced tasks.
VXDIAG DoIP Option 1 vs Option 2:
Option 1 generally refers to a standard DoIP implementation based on Ethernet and IP protocols. This means the DoIP protocol runs over conventional Ethernet architecture, suitable for basic diagnostic tasks with relatively low bandwidth requirements. This implementation is widely used in earlier vehicle models or basic diagnostic systems, primarily for functions like reading and clearing fault codes, real-time data streams, sensor data, and other essential tasks.
2. Option 2: High-Bandwidth DoIP Implementation
Option 2 refers to a high-bandwidth DoIP implementation, usually utilizing 10Gb Ethernet or higher bandwidth networks, and supporting more complex protocols and architectures. This implementation can handle higher data transfer rates, suitable for more complex diagnostic tasks like ECU programming, software updates, and intricate fault diagnostics.
Both options are part of the DoIP standard and are used depending on the specific requirements of the diagnostic task and the available infrastructure.
2.Voltage Range
-
VCX PLUS: Operates between 7V–32V.
-
VCX SE: Works between 9V–36V, but the user notes that voltage fluctuations can damage the device.
3. WiFi
VCX PLUS also has WiFi and it also works stably.
VCX SE is compact, well assembled, stable WiFi
4. Build Quality & Design
-
VCX PLUS:
- The VCX PLUS is well made, very solid and heavy.
-
Comes in a heavy-duty aluminum case (weighs ~3 kg).
The box is also very high quality and has thick plastic.
-
Features rubber padding for shock resistance.
-
Includes LAN cable, USB adapter, and a detailed manual.
-
VCX SE:
-
More compact and lightweight.
-
Still well-built with durable plastic casing.
-
5. Connection Speed & Reliability
-
The VCX PLUS connects faster to newer vehicles due to enhanced protocol support.
-
The VCX SE is slower but still reliable for older models (2004–2020).
6. Vehicle Coverage
Both device works with Mercedes-Benz C6 and other brands with license (Porsche, Honda, Ford, Mazda, Toyota, etc.).
Which One Should You Buy?
Choose VCX PLUS If:
✔ Need DOIP v2 support for high-speed advanced diagnostics.
✔ Want faster scanning speeds and broader vehicle coverage.
✔ Require a heavy-duty, rugged scanner for professional use.
Choose VCX SE If:
