A Complete Guide to Legality, Safety, Tyres, Fitment and Getting It Right Changing the wheels on a car is one of the most popular modifications people make. A larger set of alloy wheels can completely transform the appearance of a vehicle. A car that looks ordinary on standard 16-inch wheels can look much more aggressive and sporty with 18, 19 or even 20-inch alloys. But what happens if your car currently has 16-inch wheels and you want to fit 18 or 20-inch wheels? Follow Car Guru DIY Blog Is it legal? Will the car still pass its MOT? Will the larger wheels damage the suspension? Will the tyres rub against the arches? Will your speedometer become inaccurate? And perhaps most importantly: how do you make sure the modification is actually safe? The short answer is that increasing wheel diameter from 16 inches to 20 inches can be possible, but you cannot assume that any 20-inch wheel will fit simply because the bolt pattern looks correct.

Testing the Latest V2.1 Super Mini ELM327 Bluetooth OBD2 Scanner
If you’re a car enthusiast, mechanic, or DIYer who loves diving under the hood, you know how invaluable an OBD2 scanner can be. Recently, I got my hands on the Latest V2.1 Super Mini ELM327 Bluetooth OBD2 Scanner, and I decided to put it to the test. On my YouTube channel, you can see the full demonstration but here’s a detailed breakdown of my experience, its features, and why it’s a must-have tool for any vehicle owner.
What Makes the ELM327 V2.1 Super Mini Scanner Special?
The ELM327 V2.1 is a compact yet powerful Bluetooth OBD2 scanner designed to support multi-brand CAN-BUS systems. Unlike older, bulkier scanners, this “super mini” device is easy to carry, plug in, and use — whether at home or on the go.
Multi-brand compatibility: Works with virtually all OBD2-compatible vehicles.
Supports all OBD2 protocols: From CAN-BUS to older protocols, ensuring maximum coverage.
Bluetooth connectivity: Works seamlessly with Android, Windows, and even Symbian devices.
Extensive code database: Over 3,000 generic trouble codes, plus manufacturer-specific codes.
Compact design: Fits easily into your pocket, making it convenient for quick diagnostics.
This isn’t just a generic tool it’s designed to give you a professional-level experience in a tiny package.
How I Tested the ELM327 V2.1
During my test, I connected the scanner to my vehicle’s OBD2 port usually located under the dashboard near the steering column. Within seconds, it paired with my Android smartphone via Bluetooth. The accompanying app automatically recognized the car and started scanning for diagnostic trouble codes (DTCs).
The scanner can read both generic codes (like P0300 for random misfires) and manufacturer-specific codes unique to my car’s brand. In my test, it successfully detected several stored codes, displaying their meanings directly on the screen. Having over 3,000 generic definitions in the database makes understanding your vehicle’s issues easier than ever.
Features I Loved
Instant Code Reading: Once plugged in, the ELM327 began reading codes almost immediately no complicated setup required.
Clear Code Definitions: Every error was displayed with its full description, so there was no need to look up the code separately.
Real-Time Data: Beyond DTCs, it can display live sensor readings such as engine RPM, coolant temperature, and more.
Compatibility Across Devices: Tested on my Android phone and Windows laptop both worked flawlessly.
Compact and Portable: The mini design is convenient for keeping in your glove box or toolbox.
Who Should Use the ELM327 V2.1 Scanner?
This scanner is ideal for anyone who wants to diagnose car issues quickly and effectively:
DIY mechanics: Understand what’s wrong before visiting a workshop.
Car enthusiasts: Monitor performance and tweak systems safely.
Fleet operators: Keep multiple vehicles in top condition by quickly reading codes.
Professional mechanics: As a backup scanner or quick diagnostic tool for client vehicles.
Even if you’re not a professional, the user-friendly interface and clear code definitions make it simple to use. You don’t need to memorize cryptic codes or pay for expensive diagnostics every time your check engine light comes on.

Most car interiors compete for your attention. Screens multiply. Menus expand. Information floods every corner of the cabin. Then there’s McLaren. In some McLaren road cars, pressing Track mode does something unexpected: the instrument cluster partially folds away. The result feels almost surreal the first time you see it. The large digital display collapses into a narrow strip. Most of the dashboard disappears from your field of view. What remains is only the essential information: speed, gear, and a few critical indicators. Suddenly, the cockpit feels less like a luxury sports car and more like an aircraft. And that’s exactly the point. Follow CarGuruDIY Blog Enjoying my DIY car content?
