In an April 21, 2025 video, Neil from Mid Life Motors uses an iCarsoft CR Pro for his first hands-on OBD scanner experience. Working on a Mercedes-AMG SLK 55, he moves from warning lights to a precise right-front wheel-speed-sensor diagnosis, completes the physical repair, clears the stored codes and finishes with a successful road check.
The iCarsoft CR Pro gives this DIY repair a clear diagnostic path from symptom to confirmation. It powers up from the vehicle, reads the VIN automatically, identifies the Mercedes correctly, scans multiple control modules and pinpoints a right-front wheel-speed-sensor malfunction. After the sensor is replaced, Quick Erase clears the stored faults, the warning lights go out and the reviewer reports a clean road test.

What the Reviewer Tested
- Box contents and setup: the video shows the CR Pro, carry case, diagnostic lead, power/USB cable, memory card, card reader and manual.
- Vehicle-powered startup: connecting the scanner to the OBD port turns it on immediately.
- Automatic VIN identification: the tool reads the VIN, matches the final digits known by the owner and identifies the AMG SLK 55 / chassis 172.
- Multi-module Auto Scan: the scan progresses through engine electronics, stability, parking brake, radar, camera, lighting, instrument and other systems shown on screen.
- Fault-code reading: the reviewer opens the fault entry and reads the right-front wheel-speed-sensor malfunction.
- Post-repair rescan and Quick Erase: after replacing the sensor, he rescans, selects the F2 Quick Erase function and clears the stored faults.
- Road confirmation: the dashboard warnings remain off during the filmed drive, and the reviewer reports normal braking and acceleration behavior.
Features Demonstrated
| Feature | Evidence in the Video | Classification |
|---|---|---|
| Wired, vehicle-powered operation | The CR Pro powers on as soon as it is connected to the Mercedes OBD port | Demonstrated |
| Automatic VIN reading | The tool reads the VIN and identifies the AMG SLK 55 / chassis 172 without manual vehicle entry | Demonstrated |
| Auto Scan across vehicle modules | The progress screen moves through multiple control systems and returns a fault overview | Demonstrated |
| Read fault codes | The CR Pro displays the right-front wheel-speed-sensor malfunction and signal/message fault | Demonstrated |
| Quick Erase | After the sensor replacement, F2 Quick Erase is run and the scan entries change to pass | Demonstrated |
| Dashboard warning-light clearance | The reviewer shows that the warning lights have gone out after the erase process | Demonstrated |
| Manual vehicle selection | The reviewer notes that manual vehicle entry is available if needed | Mentioned |
| PC-based updates | The reviewer shows the memory card and card reader and mentions lifetime downloads and updates | Shown / mentioned |
Current CR Pro Specifications — Official iCarsoft US Source
The video documents one Mercedes repair completed in April 2025. The current iCarsoft US product page lists a broader CR Pro feature set. These are official product specifications, not additional procedures completed in the video:
- Full-system diagnostics: access to available vehicle modules for code reading and clearing, ECU information, live data and freeze-frame data.
- 58 vehicle makes are listed on the current US product page.
- Nine service functions are listed, including oil, EPB, SAS, DPF, ABS bleeding, BMS and TPMS-related functions.
- AutoVIN identification and manual vehicle selection.
- Ten OBD2 test modes for supported OBDII/EOBD/JOBD/KOBD/CAN/CAN-FD vehicles.
- 4-inch TFT display: 480 × 320 resolution with physical-button navigation.
- Lifetime free software updates through the included TF card reader and a Windows PC.
- OBDII-powered operation: official input range is 9–18V.
Compatibility notice: Diagnostic depth, AutoVIN, individual modules, code-clearing behavior and service functions depend on the vehicle brand, model, production year, ECU/module configuration and installed software version. Confirm VIN-specific coverage before purchase, especially when one particular module or maintenance function is essential.
What the Reviewer Liked
The most convincing strength is how approachable the CR Pro makes a real fault-finding job for a first-time scanner owner. Neil starts outside his comfort zone, yet the on-device prompts, VIN reading and structured scan lead him to a specific corner of the car: the right-front wheel-speed sensor. That removes guesswork from a repair involving four possible sensor locations.
He also values the complete workflow. The same compact tool that identifies the fault is used again after the physical repair to clear the stored codes and confirm a pass result. With the warning lights off and the road check going well, he gives the CR Pro a thumbs-up, recommends this type of tool for DIY mechanics and says the repair helped him avoid another garage bill while getting the car back on the road quickly.
Who This Scanner Is For
The CR Pro is a strong fit for hands-on owners who want more direction than a basic engine-code reader can provide. In this video, that means automatic Mercedes identification, access to several vehicle modules and a fault description specific enough to support a targeted wheel-speed-sensor repair.
It also suits multi-car households and independent technicians who prefer a dedicated, cable-connected scanner with physical controls and no required phone-app workflow. The current official specification extends the appeal with broad brand coverage, nine service functions and lifetime updates, subject to VIN, module and software compatibility.
Final Verdict
Mid Life Motors gives the iCarsoft CR Pro a particularly useful real-world test because the scanner is part of a completed repair, not just a menu tour. It identifies the car, scans multiple systems, names the right-front wheel-speed sensor as the problem and then returns after the component replacement to clear the stored faults.
The final outcome is positive and easy to follow: scan entries show pass, dashboard warnings go out and the reviewer completes a road check without their return. For DIY owners who want a standalone tool that can turn confusing warning lights into a practical next step, the CR Pro comes across as capable, accessible and valuable. Vehicle-specific coverage still depends on the exact VIN, control modules and installed software.
