Our mobile diagnostic service uses dealer-level scanners to read fault codes, live data and manufacturer updates wherever your vehicle is parked. That means quicker decisions, and no need to tow the car anywhere.

Why choose mobile diagnostics

Modern cars are packed with sensors and control units, and when something goes wrong the dashboard just lights up. Our IMI-qualified mechanic arrives with advanced Autel and Snap-On equipment, checks each module and explains the results in plain English.

Because we come to your driveway or office car park, the fault can be checked in real-world conditions, which means less guesswork and fewer unnecessary parts. Once the problem is confirmed we can often repair it there and then, saving you time and money.

Common faults we diagnose

Our tools read the powertrain, body, ABS, airbag and climate modules on most makes and models. Instead of swapping parts until the light goes out, you get a clear answer and a report with the recommended fix.

  • Engine management lights
  • Misfires
  • DPF and EGR problems
  • Sensor failures
  • Battery drain
  • Network communication faults
  • ABS and airbag warnings
  • Climate control faults
  • Electric windows and body electrics

Ideal for private motorists, tradespeople and fleet operators alike.

How our diagnostics work

  1. Read the fault codes

    Dealer-level equipment reads every stored code from every module.

  2. Check the live data

    We watch the sensors in real time to confirm what the codes suggest.

  3. Road test

    Where it helps, we drive the car to reproduce the fault.

  4. Talk it through

    We explain what is wrong and your repair options before any work starts.

After the scan: repairs and support

Reading the fault code is only half the story. Once we have isolated the root cause we can source quality replacement parts, update software or repair wiring on site. We clear the codes, retest the system and give you a digital report for your records.

If the job needs workshop equipment, we arrange transport and oversee the work, so you are never left guessing. The aim is always a first-time fix and complete peace of mind.

Diagnostics questions

All questions

What vehicles can you repair and service?

Most petrol and diesel vehicles up to 3.5 tonnes, from small city cars to light commercial vans. That covers family hatchbacks, 4x4s, motorhomes, company cars and fleet vans from all the major manufacturers. We carry dealer-level diagnostics for popular makes such as Ford, Vauxhall, Volkswagen and Mercedes. If you drive something more specialised, give us a call and we will check parts and let you know how soon we can come out.

How much does a typical repair cost?

Without the overheads of a fixed garage, our labour rates are usually lower than main dealers and many local workshops. Prices depend on the job, the make and the parts needed, but you always get a clear quote before any work starts. There are no hidden call-out fees within our normal area, and we will tell you if a repair would not be worth it compared with what the car is worth.

A photo of the warning light, the tyre sidewall or the damage helps us give you a closer price.
