AI Receptionist for vehicle diagnostics garages
Dashboard lights don't wait. Neither should your booking call.
Ava is the AI receptionist for vehicle diagnostics garages that captures the fault code and books the scan — while your technician works.
A diagnostic scan at £50–£120 opens a repair conversation worth £80–£450 on average. Each missed booking call loses both — three a week is up to £1,700 in lost diagnostic and repair revenue.
The short answer
- 1. Diagnostic enquiries are triggered by warning lights — the motorist is anxious, often unsure of urgency, and will book with whoever answers and sounds competent first.
- 2. Ava asks which warning light is showing, the vehicle make and model, and whether the vehicle is driveable — capturing the urgency triage information your technician needs before the scan.
- 3. A scan at £50–£120 is the entry point for repair conversations worth £80–£450. Missing the diagnostic call loses both.
- 4. Ava integrates with TechMan, MAM Autoware, and Garage Hive — writing the scan booking with the fault description into your DMS before the call ends.
- 5. For vehicles she identifies as potentially unsafe to drive — brake warning lights, oil pressure, or temperature gauge faults — she flags the call as urgent and routes it to your team immediately.
The problem
A motorist's engine warning light comes on during the school run. They pull over, Google the nearest diagnostic centre, and call. You're mid-diagnosis on another vehicle. The phone rings out. They call the next garage. Your diagnostic bay sits idle.
What Ava does
Ava answers every diagnostic enquiry, establishes which warning light is showing and the vehicle make and model, captures the urgency, and books the scan appointment — routing genuinely urgent cases to your team immediately.
A diagnostic scan costs £50–£120. But the fault code almost always leads to a repair conversation: a DPF clean at £150–£300, a sensor replacement at £80–£200, or an ECU remap at £250–£450. The scan is the door; the repair is the margin.
How does an AI receptionist handle a diagnostic enquiry when a technician is mid-scan?
Ava answers immediately, asks which warning light is showing and whether the vehicle is exhibiting any other symptoms — juddering, smoke, or loss of power — then establishes whether the vehicle is safe to drive to the garage. She books the scan slot and captures the fault context so your technician prepares the right analyser for the vehicle.
Diagnostic enquiries are among the most anxiety-driven calls a garage receives. The motorist does not know whether they have a £50 sensor swap or a £2,000 engine problem. Ava's role in the first thirty seconds is to calmly establish whether the vehicle is safe to drive, capture the warning light and any accompanying symptoms, and convert that anxiety into a booked appointment.
The make and model matter for diagnostic preparation. A Volkswagen Group DPF fault requires a different set of software licences and adapters than a Ford TDCI injection issue. Ava captures this detail so your technician sets up the correct diagnostic kit before the vehicle arrives, reducing the appointment time and improving the first-fix rate.
Pre-purchase diagnostics are a growing call type as used car buyers seek independent checks before committing. These are typically booked 24–48 hours ahead and generate a clean, fee-only invoice. Ava handles these enquiries with the same structured capture, noting that the caller is a prospective buyer rather than the registered keeper, which affects how the report is framed.
Why is the diagnostic booking call the most valuable call a garage can answer?
The diagnostic scan at £50–£120 is a door-opener, not the revenue event. The revenue event is the repair conversation that follows the fault code. Each missed diagnostic booking loses the scan fee and the average £80–£450 repair it would have led to. Three missed calls a week is up to £1,700 in combined lost revenue.
Motorists who call about a warning light are already committed to spending money — they just do not know how much. Unlike a tyre price-shopper or a service caller who might defer, a warning-light caller has a car that is telling them something is wrong. They will book the diagnostic today, with whoever answers.
The fault-to-repair conversion is where the diagnostic margin compounds. A DPF cleaning job found on a diagnostic scan runs £150–£300 and takes two hours. An oxygen sensor identified on the same scan takes forty-five minutes at £80–£150. A throttle body cleaning or EGR valve replacement adds another £100–£200. The scan is what enables the conversation; the conversation is what fills the ramp.
Post-diagnostic retains are also high-value. A motorist who came in for a scan and was treated well, quoted clearly, and had their repair completed efficiently is likely to return for their MOT, their next service, and to recommend the garage. The warning-light call that is answered is the beginning of a relationship, not a one-off transaction.
Does Ava triage urgent diagnostic calls from vehicles that are unsafe to drive?
Yes. Ava asks a short urgency triage: is the warning light accompanied by smoke, unusual smells, power loss, or a brake warning? If the vehicle shows signs of being unsafe to drive, she flags the call as urgent and routes it to your team immediately for same-day or emergency advice. She does not leave a potentially dangerous vehicle unaddressed.
An oil pressure warning, a temperature gauge in the red, or a brake system fault indicator are not standard booking scenarios. Ava is trained to recognise these descriptions and escalate them rather than putting them in the next available scan slot. The motorist is asked to stop driving if they have not already done so, and your team receives the alert with the caller's location and number.
Standard non-urgent warning lights — engine management, TPMS, service due, or airbag indicators that have been showing for several days without worsening — are handled as normal scan bookings with the appropriate slot in your diagnostic diary.
Every triage decision Ava makes is logged against the booking record in TechMan or MAM Autoware, so your technician can see both the caller's description and the urgency classification before picking up the vehicle keys.

Hear it in action
This is what your callers hear.
- Good morning, PrecisionDiag — how can I help?
- My engine management light came on this morning. The car seems to be running fine but I'm a bit worried.
- I understand — it's always worth getting it checked. Can I ask the make, model, and rough mileage, and confirm the car is driving normally apart from the light?
- It's a BMW 3 Series, about 68,000 miles. Yes, drives fine.
- That sounds like something we can diagnose quickly. I have a scan slot available tomorrow afternoon — shall I book you in?
Before you choose
What to look for in an AI receptionist for diagnostics.
Warning light triage built in
The AI must differentiate between a non-urgent engine management light and a brake or oil pressure warning that may indicate a vehicle unsafe to drive. A system that treats all warning lights identically will leave a dangerous vehicle in a normal booking queue.
Make and model capture for kit preparation
Diagnostic equipment is brand-specific. The AI must capture the make, model, and engine type so your technician prepares the correct analyser and software licence before the vehicle arrives.
Fault context in the job card
The fault description the motorist gives on the call — even if imprecise — is valuable context for your technician. It should arrive in TechMan or MAM Autoware with the booking, not sit in an email no one reads before the vehicle arrives.
Pre-purchase diagnostic handling
Pre-purchase checks are a distinct booking type with different output requirements. Check that the AI can capture buyer-versus-keeper context and note it on the job card so your technician frames the report correctly.
Common questions
Everything you’re wondering.
Can Ava book a diagnostic scan while a technician is running another scan?
Yes — that is what she is designed for. Ava answers every diagnostic call during workshop hours and out-of-hours, captures the warning light and vehicle detail, and books the scan slot without interrupting your team.
How does Ava handle a caller whose warning light suggests the vehicle may be unsafe?
Ava asks about accompanying symptoms — power loss, smoke, smell, or brake behaviour — and if the description suggests a potential safety issue, she routes the call to your team as urgent rather than putting it in a standard booking slot.
Can Ava capture the fault code if the caller already has a reading?
Yes. If a caller has used an OBD reader and has a fault code, Ava captures it and includes it in the job card note so your technician can check the code before the appointment and prepare any specific parts.
Does Ava integrate with TechMan or MAM Autoware for diagnostic bookings?
Yes. Ava integrates with TechMan, MAM Autoware, Garage Hive, and Motasoft, writing the scan booking with the warning light description and vehicle make and model directly into your DMS.
Can Ava handle pre-purchase diagnostic enquiries as well as current-owner checks?
Yes. Ava identifies pre-purchase callers, captures the vehicle registration and the sale context, and books the inspection with a note that the output will be a buyer's report rather than a standard fault diagnosis.
What if the caller cannot describe the warning light accurately?
Ava uses plain language prompts — asking about the light's colour, shape, and what the car is doing — to identify the most likely system. She captures the description verbatim in the job card so your technician has the full picture.
How long does setup take for a diagnostics garage?
Typically 48 hours. We configure Ava on your scan types, vehicle makes you service, urgency protocols, and DMS, then test against real diagnostic call scenarios before she goes live on your line.
Pricing
Ava pays for herself on call one.
A diagnostic scan costs £50–£120. But the fault code almost always leads to a repair conversation: a DPF clean at £150–£300, a sensor replacement at £80–£200, or an ECU remap at £250–£450. The scan is the door; the repair is the margin. Plans from £397/mo. One recovered job a month covers it — everything else is pure upside.
