Key differences

Design and specifications

The design differences between the ANCEL BM500 and BM700 are subtle. The BM700 has a slightly larger screen, making it easier to read graphed information and other data. Its button panel also has two convenient hotkeys for quickly checking emissions or reading fault codes, which you won’t find on the simpler interface of the BM500. 

Overall features and functions

Firstly, the base features of the ANCEL BM500 are focused on OBD2 diagnostics. It’s a useful OBD2 scan tool, with functions like reading and erasing trouble codes, viewing freeze frame or live data, and checking whether your vehicle is ready for an emission test. Additionally, it can test the battery voltage to help diagnose starting issues. 

BM700 offers similar basic functions, with battery testing and 6 modes of OBD2 testing available for vehicles from any manufacturer. It’s a robust OBD2 scanner, capable of testing the EVAP system and retrieving VIN information along with reading codes and viewing PID data streams.  

Extra features/functions

For BMW Group vehicles, the ANCEL BM500 is an all-system OBD2 diagnostic tool. It reads and clears trouble codes from all the on-board systems, including the transmission, HVAC system, and even your headlights and audio system. Bi-directional control lets you activate specific components in the ABS or SRS systems and more easily identify the source of trouble codes. 

The ANCEL BM500 also supports a range of useful maintenance functions for vehicles in the BMW group. DIY mechanics will love features like battery registration, oil reset, and electronic parking brake service, allowing you to perform necessary vehicle maintenance at home. 

Whereas, BM700 adds a range of professional features to the advanced functions offered on the BM500. This includes calibration and programming features like relearning the steering angle, injector coding, and idle speed adjustment, giving you complete control over the vehicle’s performance. 

Supported protocols

The ANCEL BM700 and BM500 both support all OBD2 protocols, including J1850 VPW, J1850 PWM, ISO9141, KWP2000, and CAN networks. 

Supported vehicle makes

Some functions of the ANCEL BM500 will work on any vehicle with a 16-pin OBD2 port, which includes all cars and light trucks sold in the United States after 1996. This universal compatibility applies to the OBD2 diagnostics and battery test functions of this ANCEL code reader. 

The advanced diagnostic and maintenance functions of the BM500 are supported for most vehicles manufactured by the BMW group. Supported BMW models include vehicles from 22 BMW series from 1996-2020, including X, Z, and I series. You’ll also get these advanced functions on many Rolls Royce and Mini models that use a 16-pin diagnostic port. 

The vehicle compatibility of the BM700 includes all those supported by the BM500. Along with that, you can use this OBD2 scan tool with many older BMW group vehicles that use a 20-pin diagnostic port. While you will need to buy an adapter to use the ANCEL BM700 OBDII scanner with these models, its broader support makes it a more versatile option for both mechanics and enthusiasts. 

Software and updates

BM500 and BM700 are usable right out of the box, without the need to first register the tool or download updates. When updates are available, they’re free for life and easy to download and install from ANCEL’s website. You will need to have a PC with a Windows operating system to download updates, something to keep in mind for Mac and Linux users.

Does the ANCEL BM500 support brake bleeding?

💡 Yes, you can automatically bleed the brakes with both the ANCEL BM500 and BM700 diagnostic tool.

Can the ANCEL BM500 turn off the brake warning light on the dash?

💡 Yes, you can reset the EPB system using the ANCEL BM500. This allows you to turn the dash warning light off once you’ve made repairs or replaced the brake pads. 

How can I find out which features of the BM500 or BM700 are supported for my vehicle?

💡 The best bet is to reach out to ANCEL support with your specific vehicle make and model year and the model number of the scan tool you’re considering. They’ll let you know whether it supports the features you need. 

Will the BM500 or BM700 work on BMW motorcycles?

💡 Not right out of the box. While many motorcycles do have an on-board diagnostic protocol, they don’t use an OBD2 connector. If you have the right adapter, you may be able to use these ANCEL scanners to run basic OBD2 diagnostics on a motorcycle. However, you shouldn’t expect to access the advanced features available for 4-wheeled BMW vehicles. 

Will ANCEL BM700 work on BMW vehicles sold in Europe?

💡 The BM700 OBDII diagnostic tool supports EOBD as well as OBD2 protocols and should work just as well on European BMWs as it does on those from the US. If you want to be sure, reach out to ANCEL support.

Comparing the ANCEL BM500 vs. BM700, you’ll see the BM700 is the professional upgrade of the BM500 ANCEL scanner. While the advanced coding and adaptation features of the ANCEL BM700 give it excellent value for professionals, the lower cost and more straightforward interface of the ANCEL BM500 could be the better choice for hobbyists. 

Whichever of these ANCEL scan tools you buy, you can count on them to provide accurate diagnostics and useful maintenance functions for any BMW Group vehicle. We hope this review has helped you decide which one best fits your needs!
