Why choose Car Care for your diagnostic

With Car Care, The AA’s mobile mechanics deliver the ultimate in convenience and quality.

AA experts you can trust

Fully trained AA mechanics, backed by 120 years of motoring expertise.

30 minutes of fault finding for £99

We’ll bring everything we need to look into the problem and leave your space just as we find it.

No hassle – we come to you

No garage trip or waiting – hand us your keys in your two-hour arrival slot.¹ We’ll do the rest.

Same day appointments

We’ll aim to get to you the same day if you book before 5pm, depending on availability.⁵

What is a car diagnostic?

A car diagnostic is an appointment to find the cause of a fault

One of our mobile mechanics will come to your home or work and spend up to 30 minutes checking your car. Same day appointments available.⁵

  • We’ll provide expert advice and a written report you can trust. Even better, one in four jobs are fixed there and then.
  • If we can’t fix it, we’ll make recommendations for your next steps and quote for any follow-up repair, if needed.
  • We'll help diagnose the fault, but repairs are quoted separately, with no obligation.

What happens during a car diagnostic?

We’ll check your car to find out what’s going on

  • Our mobile mechanic will arrive with the same equipment garages use and spend up to 30 minutes checking your car over.
  • We’ll ask about your experience of driving the car to find out what you’ve noticed, and we might take the car for a test drive.
  • Where possible, we might reset dashboard warning lights, and we’ll explain what we’ve found and what we recommend you do next.

How long does a car diagnostic take?

We’ll spend up to 30 minutes finding the fault

  • Once our mobile mechanic has completed the checks needed, they’ll explain what they’ve found and recommend next steps.
  • If it’s something we can fix right there, we might be able to get you back on the road straightaway. Any repairs are quoted separately, with no obligation.

How does Car Care work?

On your schedule

Choose a date and arrival window, Monday to Saturday, 8am to 8pm. An AA-trained mechanic will come to your home or work with everything they need.

At your location

You just need a suitable space. It should be well lit, on private land, with a place for the mechanic to park nearby, and a metre of space all the way around the car.3

Make the most of your day

No need to arrange a lift to or from the garage. Simply pass us the key and get on with your day. Parts guaranteed for 12 months or 12,000 miles.4

Our Mobile Mechanics Fault Finding service is just £99.

Our vetted, uniformed, AA-employed experts use the latest diagnostic equipment and are trained mechanics backed by the 120 year history of the AA, who understand the technology, and can recommend what to do to get your car repaired.

For £99, we will come to you and figure out what's wrong. If we find the fault, and have the ability and the parts to do so, then we will fix it right then and there. The two main reasons we can’t fix faults right there and then, is (1) if we require a part that we don't have with us, in this scenario we can book a follow-up visit to complete when convenient for you or (2) if the fix requires a garage or original equipment manufacturer visit, and we’re not best placed to fix it.

We carry some parts in our vans, however if you know that you need something specific, you can always let us know and we will bring it along. You will get a full quote for repairs before do any extra work, and will always be offered a suitable time for us to complete that. You can even take your diagnostic report to another garage to get the work done, if you would like. And if the fault turns out to be something you don't fix (like bodywork), we will give you advice on how to get repaired and AA approved repairers.

Yes, we can check for any issue you have with your car on your driveway, or private land as long as you have permission to use it. For the safety of our mechanics and the public, we cannot work on vehicles parked on a public road.
