VXDIAG VCX SE vs Openport vs MB SD C4 for 2025.09 Xentry
Purpose: Test VXDIAG VCX SE, Openport 2.0 and MB SD Connect C4 on the same car (Mercedes E-class W213) and the same diagnostic software (Xentry 2025.09)—to objectively measure performance, specifically the connection speed.
Scanner Overview
1. Openport 2.0 (J2534 Clone)
Price: Approximately $15.
Vehicle Coverage: Works with models from 2004 up to 2020/2021. For 2021+ models, a special certificate may be required for diagnosis.
Key Features: This is a clone of the original multiplexer. It can be used to activate features like the AMG menu using MB Tools with an internet connection.
Pros: Extremely cheap and does its basic job well.
Cons:
Works with xentry passthru version only.
Cannot perform firmware updates (flashing).
Not compatible with very old or the very newest models.
The connector is flimsy and detaches easily.
2. VXDIAG VCX SE Benz (Spoofed as Original VCI)
Price: Approximately $229.
Vehicle Coverage: Reads vehicles from 2004 up to 2025, including the latest models. For cars above 2021, a separate coding certificate is required (approx. $150/hour, but currently difficult to purchase).
Key Features: This device has DoIP (Ethernet) capability, allowing it to connect to new platforms like the 206, 223, EQ, and EQS. It features Wi-Fi for cable-free operation.
Pros:
Very convenient and compact.
Compatible with both Xentry Openshell and Passthru version.
Can perform firmware updates.
Multi-brand (works with BMW, GM, etc.).
Cons:
Not compatible with very old Kline models.
Works only a few truck models.
3. MB SD Connect C4 (Clone)
Price: Approximately $400-$500.
Vehicle Coverage: Comes in two versions: a basic one (similar to Openport, covering up to ~2021) and a DoIP version for the latest models. A key advantage is its ability to diagnose older cars (e.g., from 2001) and Mercedes trucks, which the VCX cannot do.
Key Features: The original C4 is not sold new to the public; only used units from closed official service centers or copies are available.
Pros: Powerful, works with a wide range of vehicles including classics and trucks.
Cons:
Very heavy, bulky, and inconvenient.
The cable is large.
The clones typically do not have functional Wi-Fi, requiring a cable connection.
Note on “Blacklists”: blacklists are only a concern for online operations. For offline diagnostics (which is how most independent shops and enthusiasts operate), whether a scanner is blacklisted is irrelevant
Speed Test Results: Connection Times
The test measured the time taken to perform key actions from a cold start.
| Test Action | Openport 2.0 | VXDIAG VCX SE | C4 |
|---|---|---|---|
| Initial Vehicle Connection | 1 minute 8 seconds | 51 seconds | 22 seconds |
| Short Test | 1 minute 45 seconds | 1 minute 8 seconds | 24 seconds |
| Access Engine Control Unit | 7 seconds | 13 seconds | 7 seconds |
| Access Ignition Lock Module | 2 seconds | 2 seconds | 2 seconds |
The C4 was the fastest scanner by a significant margin in initial connection and system-wide tests. The VCX SE performed solidly, offering a good balance of speed and modern features. The Openport 2.0, while functional, was the slowest, reflecting its budget nature.
Your choice should depend on your needs and budget:
-
For Hobbyists on a Budget: The Openport 2.0 is a capable tool for basic diagnostics on models up to 2020.
-
For Professional Multi-Brand Use: The VXDIAG VCX SE is the best choice due to its compact size, Wi-Fi capability, firmware flashing support, and compatibility with other car brands.
-
For Mercedes-Only Specialists Needing Maximum Performance: The C4 is the undisputed performance leader. It is ideal for those who work extensively with Mercedes passenger cars and trucks and value raw speed above portability.
