Why workshops buy from us, and keep buying.

Mechanics first, suppliers second. Every tool we sell has been in our workshop or a customer's workshop before it goes in front of you. When you call, you get someone who's held the tool, used it on a vehicle, and can walk you through whatever procedure is giving you grief.

About Andrew & Techno Diagnostics
  • On-site demo, no charge.

    We bring the tool to your bay. You plug it into the next job on the diary. Buying decision made with hands on the hardware.

  • Installed before we leave.

    Software activation, WiFi, licence keys, adapter libraries. Done on the day. Your techs aren't waiting on a setup ticket.

  • Training on your own vehicles.

    Hands-on sessions on cars from your own booking diary. Not a generic walk-through on a demo car the rep brought along.

  • UK warranty, UK phone number.

    Hardware fault? You ring us. We chase it with the manufacturer. No European call centres, no ticket numbers.

Not sure which tool fits? Ring us and tell us the work.

Most workshops buy too much tool or too little. A ten-minute call with Andrew sorts it. Bring your weekly vehicle mix and the fault types you keep seeing.
