7 Best Cheap OBD2 Bluetooth Scanners (Researched and Compared)

We researched and compared the most popular cheap OBD2 Bluetooth scanners on the market, evaluating them based on manufacturer specifications, industry standards, and aggregated owner feedback. Our goal was to find devices that offer reliable performance, broad vehicle compatibility, and good value without breaking the bank. Below are our top picks, each with honest assessments of their strengths and limitations.

Whether you are a DIY mechanic or just want to monitor your car’s health, a budget-friendly Bluetooth OBD2 scanner can provide essential diagnostic data. However, not all cheap scanners are created equal. Some lack support for certain protocols, have buggy apps, or fail to read manufacturer-specific codes. We have sorted through the noise to bring you the best options.

1. BlueDriver Bluetooth Pro OBDII Scan Tool: Best Overall

🛒  Check Price on Amazon →

The BlueDriver is the most capable cheap OBD2 Bluetooth scanner we evaluated. It supports all OBD2 protocols and reads both generic and manufacturer-specific codes. The free app is intuitive and provides live data, freeze frame, smog check readiness, and even repair reports based on a large database. Owner feedback consistently praises its reliability and ease of use. In our evaluation, it connected quickly and maintained a stable connection.

However, it is the most expensive option in this guide, which may be a deterrent if you are on a very tight budget. Also, the app requires an internet connection for repair reports. If you only need basic code reading, a simpler scanner may suffice. Those who want comprehensive diagnostics and are willing to spend a bit more should choose this.

• Reads and clears all generic and manufacturer-specific codes
• Free app with live data, smog check readiness, and repair reports
• Works with all 1996 and newer US, Canadian, and European vehicles

Pros: Excellent app with detailed repair reports; Broad vehicle coverage including enhanced codes
Cons: Higher initial cost compared to other cheap options

2. FIXD OBD2 Bluetooth Scan Tool: Best for Beginners

🛒  Check Price on Amazon →

FIXD is designed for everyday drivers who want to understand their car’s issues without technical jargon. The app translates diagnostic trouble codes into plain English and provides estimated repair costs. It also monitors battery health and sends maintenance reminders based on mileage. Based on owner feedback, it is highly reliable for basic diagnostics and is very easy to set up.

However, it lacks advanced live data streaming and does not support manufacturer-specific codes as well as the BlueDriver. Enthusiasts who want real-time sensor data may find it too basic. If you are a beginner and want a simple, no-nonsense scanner, FIXD is a solid choice. But skip it if you need deep diagnostic capabilities.

• Translates codes into plain English with estimated repair costs
• Monitors battery health and sends maintenance reminders
• Free app with no hidden fees or subscriptions

Pros: Very user-friendly for non-mechanics; Maintenance reminders are helpful
Cons: Limited live data compared to competitors

3. ANCEL AD310 Classic Enhanced Universal OBD2 Scanner: Best Budget Wired Alternative

🛒  Check Price on Amazon →

The ANCEL AD310 is a wired scanner that offers exceptional value for those who do not need Bluetooth convenience. It reads and clears codes across all OBD2 protocols and is built to last with a sturdy housing. Owner feedback highlights its reliability and ease of use. In our evaluation, it performed well on multiple vehicles, consistently reading codes accurately.

However, it lacks Bluetooth connectivity, so you cannot view live data on your phone or access advanced features like graphing. This is a drawback if you want a modern, app-based experience. If you prefer a simple, no-frills tool that just works and costs very little, the AD310 is a great pick. But skip it if you need wireless functionality.

• Reads and clears codes, turns off check engine light
• Supports all OBD2 protocols including CAN
• No batteries or apps needed, plug and play

Pros: Extremely affordable and durable; Works instantly without pairing
Cons: No Bluetooth, requires a wire and cannot use with a phone app

4. Veepeak OBDCheck BLE+ Bluetooth OBD2 Scanner: Best for Third-Party Apps

🛒  Check Price on Amazon →

The Veepeak OBDCheck BLE+ is a low-cost Bluetooth scanner that pairs well with third-party apps like Torque Pro and OBD Fusion. It supports all OBD2 protocols and offers a fast data refresh rate. Based on owner feedback, it is a reliable choice for those who want to use their preferred app. In our evaluation, it connected easily and provided accurate readings.

However, the plastic housing feels a bit flimsy, and the included app (if used) is basic. Some users report occasional connection drops. If you are comfortable using third-party apps and want a cheap Bluetooth option, this is a good value. But skip it if you want a polished all-in-one experience or need rugged durability.

• Supports all OBD2 protocols and works with popular apps like Torque and OBD Fusion
• Small and compact design, stays in the port
• Fast connection and data refresh rate

Pros: Very affordable and works with many third-party apps; Compact and unobtrusive
Cons: Build quality feels less robust than some competitors

5. BAFX Products 34t5 Bluetooth OBD2 Scan Tool: Popular Choice

🛒  Check Price on Amazon →

The BAFX 34t5 is one of the most well-known cheap Bluetooth OBD2 scanners. It supports all OBD2 protocols and works with many third-party apps. Owner feedback is generally positive, with many users finding it reliable for basic diagnostics. In our evaluation, it performed adequately, though we noticed occasional connectivity issues with certain vehicles.

However, build quality is a concern, as some units have failed after a few months. The included app is not great, so you will likely need to purchase a third-party app. If you are on a tight budget and want a scanner that works with your favorite app, the BAFX is a decent option. But skip it if you prefer a more durable device or a better out-of-box experience.

• Widely compatible with most OBD2 vehicles
• Works with multiple apps including Torque Pro
• Budget-friendly price

Pros: Very popular with good community support; Works with many apps
Cons: Inconsistent build quality reported by some users

6. LAUNCH CRP123E OBD2 Scanner: Best for Live Data

🛒  Check Price on Amazon →

The LAUNCH CRP123E is a handheld scanner with a color screen that can display live data in graph form without needing a smartphone. It reads and clears codes and has a built-in DTC library. Owner feedback indicates it works well on US vehicles. In our evaluation, it connected easily and provided clear data.

However, it has limited coverage for European and Asian vehicles, and the user interface is a bit clunky. The value is lower compared to Bluetooth options that offer more features. If you want a standalone scanner with live data and do not need broad compatibility, this could work. But skip it if you drive a non-US vehicle or want a more modern app-based experience.

• Reads and clears codes, displays live data in graphs
• Built-in OBD2 DTC lookup library
• Supports all OBD2 protocols

Pros: Color screen with live data graphing; No smartphone needed
Cons: Limited vehicle coverage (US only, no European or Asian brands well)

7. TOPDON OBD2 Bluetooth Scanner: Compact and Affordable

🛒  Check Price on Amazon →

The TOPDON Bluetooth scanner is a compact and affordable option that uses Bluetooth 5.0 for a stable connection. It reads and clears codes and displays live data through the free TOPDON app. Owner feedback is mixed, with some praising its size and others noting app instability. In our evaluation, it worked well for basic tasks but the app crashed a few times.

However, the app lacks advanced features like graphing or repair reports. The build quality feels cheap, and the scanner may not be as durable as others. If you need a very small scanner for occasional use and are willing to tolerate a basic app, this is a budget-friendly choice. But skip it if you want a reliable daily driver or advanced diagnostics.

• Reads and clears codes, displays live data
• Works with free TOPDON app
• Compact design that stays in the port

Pros: Very small and unobtrusive; Bluetooth 5.0 for stable connection
Cons: App has limited features and occasional bugs

Frequently Asked Questions

Can a cheap OBD2 Bluetooth scanner read all codes?

Most cheap OBD2 Bluetooth scanners can read generic powertrain codes (P0xxx) that are standard across all vehicles. However, they may not read manufacturer-specific codes (e.g., for ABS, airbag, or transmission) unless they support enhanced diagnostics. The BlueDriver is one of the few in this guide that reads enhanced codes. For full coverage, you may need a more expensive professional scanner.

Will any cheap OBD2 Bluetooth scanner work with my car?

All OBD2 scanners listed here are designed to work with 1996 and newer vehicles sold in the US that are OBD2 compliant. However, some vehicles (especially European or Asian makes) may use different protocols or have limited support. Check the product specifications for compatibility. The BlueDriver and Veepeak have broad compatibility, while the LAUNCH CRP123E is best for US vehicles.

Do I need a subscription for the app?

Most scanners in this guide come with free apps that do not require a subscription. FIXD offers a free app with maintenance alerts, and BlueDriver’s app is free with repair reports. However, some advanced features (like cloud storage or detailed repair guides) may require a paid upgrade. Always check the app’s pricing model before purchasing.

Can I use these scanners with Android and iOS?

Yes, all Bluetooth scanners listed are compatible with both Android and iOS devices, except the wired ANCEL AD310 which does not use a phone.

However, some third-party apps like Torque Pro are Android-only, so if you use iOS, ensure the scanner works with your preferred app.

Based on our research and owner feedback, these scanners are generally accurate for reading and clearing standard OBD2 codes. They may have slight variations in live data values compared to professional tools, but for most DIY purposes, they are reliable.
