Why TOAF? Comparison with Testbook T4

Why TOAF when Testbook T4 exists?

Testbook T4 is the original diagnostic tool used in authorised Rover/MG dealerships. It was very advanced — but also:

• Expensive and hard to obtain
• Limited by manufacturer procedures
• Requiring licensing and authorisation

TOAF was created as an alternative

In many cases it offers capabilities comparable to T4, and even broader — because:

• No VIN matching required
• Works on individual modules independently
• Allows intervention where T4 does not
• Available to everyone — no licensing fees

As a result, TOAF has changed the way these cars are worked on — both in workshops and among private owners.
