Installing 552 “Adaptive LED Headlight” on BMW i3 I01 LCI instead of 5A2 “LED headlight” or 5A4 “LED headlight with extended scopes”. This retrofit does not require additional wiring, re-pinning or somewhat else.
Check that you have the right headlights for your vehicle: left-hand drive (LHD) or right-hand drive (RHD). Double check ECUs installed in headlights. Count and check the position of each pin in the connector. For SA 552 Adaptive LED Headlight on LCI I01 car ECU must be FLE2MAX (HWEL: 2B8F 03.01.00), P/N: 63 11 8 494 844.*
Requirements:
— Windows PC/laptop/tablet,
— ENET (or VXDIAG VCX SE BMW),
— E-Sys,
— PSdZData lite or full.
NOTE: We don’t provide E-Sys and PSdZData programs.
Installing:
0. Connect Adaptive LED Headlights to a car.
1. Connect PC to a car via ENET (or VCX SE) and run E-Sys (launcher not required) with PSdZData lite or full. Use the “Coding” section in E-Sys.
2. Remove from FA option 5A2 “LED headlight” or 5A4 “LED headlight with extended scopes” (if present).
3. Add to FA option 552. This FA can be written to VCM.

Here comes the true user review on VXDIAG VCX SE and Volvo V50.
“I tried the VXDIAG VCX SE (without a Volvo license) + VDASH (free version) combination.
Many people on the website are reporting that VXDIAG doesn’t work with the VDASH program. I decided to check, and it turns out the program recognizes the adapter and connects to the car without any problems.
I only got one error, but it seemed like a nasty one: ECM-2A50 Particle trap. Defective signal.
There are no other notifications on the dashboard, no smoke, and the car runs like it should (well, it’s clear the 1.6 is a bit of a slug, but it runs fine, revving above 3k).
UPDATE: I replaced the differential exhaust gas pressure sensor with a Meyle 714 801 0001 , and the error went away.”
Problem:
Got the vxdiag vcx nano JLR device USB version. Tried to download JLR SDD driver in vx manager but failed.
It says the device license for the application is invalid or expired. Any solution?
Solution:
Update the license first, then install/update JLR SDD driver.
Problem:
Failed to install Passthru driver for VxDiag VCX SE on Windows 10 system. Error File check failed. How to fix it?
Solution:
Exit vx manager.
Run vx manager and install passthru driver again. It should be fine.
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
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.
