When you’re buying a used car, an AA car check can seem like a reassuring safety net. But does an AA car check do diagnostics? Understanding what this popular service covers – and more importantly, what it doesn’t – is crucial for making informed decisions about your next vehicle purchase.
What Does an AA Car Check Actually Cover?
An AA car check primarily focuses on a visual inspection of the vehicle. This means a qualified inspector will examine the car’s exterior and interior for signs of damage, wear and tear, and potential issues.
Here’s a breakdown of what’s typically included:
- History Check: This verifies the vehicle’s registration details, mileage, and if there are any outstanding finance agreements or if it’s been reported stolen.
- Exterior Inspection: The inspector will check the bodywork for dents, scratches, and rust. They’ll also inspect the tires, lights, and glass for any damage.
- Interior Inspection: This involves examining the condition of the seats, carpets, dashboard, and other interior components.
- Under the Hood: The inspector will visually check the engine bay for any obvious leaks or damage. They will also check fluid levels.
- Road Test: The inspector will take the car for a short drive to assess its handling, braking, and overall performance.
Does an AA Car Check Include a Diagnostic Scan?
Here’s the catch: a standard AA car check does not typically include a full diagnostic scan. While the inspector can identify some surface-level problems, they won’t be plugging in a diagnostic tool to delve deeper into the car’s computer system.

Why a Diagnostic Scan Matters
Modern vehicles are heavily reliant on complex electronic systems. A diagnostic scan connects to your car’s onboard computer (ECU) to retrieve trouble codes and valuable data about the engine, transmission, brakes, airbags, and more.
Here’s what a diagnostic scan can reveal that a visual inspection might miss:
- Hidden Fault Codes: Your car’s ECU might store fault codes even if the warning lights aren’t illuminated on the dashboard.
- Intermittent Problems: Issues that occur sporadically, such as sensor malfunctions or electrical glitches, might not be apparent during a brief visual inspection.
- Potential Future Problems: A diagnostic scan can identify early signs of component wear that could lead to costly repairs down the road.

Should You Get a Separate Diagnostic Check?
If you’re serious about buying a used car, especially a newer model with advanced electronics, getting a separate pre-purchase inspection (PPI) that includes a diagnostic scan is highly recommended.
Here are some options to consider:
- Mobile Mechanics: Several reputable mobile mechanics specialize in pre-purchase inspections and bring their diagnostic equipment to your location.
- Specialist Garages: Many independent garages offer pre-purchase inspections as a service. Be sure to choose one with experience in the specific make and model you’re considering.

The Bottom Line: Don’t Skip the Diagnostics
While an AA car check can be a useful starting point, it shouldn’t be your only source of information when buying a used car. A full diagnostic scan provides a much deeper understanding of the vehicle’s health and can potentially save you from costly surprises in the future. Remember, a relatively small investment in a diagnostic check today could prevent major headaches and expenses tomorrow.
