For fleet operators, vehicle downtime is one of the biggest hidden costs in the business.
When a fleet vehicle requires dealer-level diagnostics, coding or programming, sending it back to the manufacturer network can mean additional costs and days of avoidable downtime.
Complete Diagnostics enables many of these procedures to be carried out remotely while the vehicle remains with your chosen repairer — helping fleet operators keep vehicles on the road, control repair costs and make better use of their existing workshop network.
Complete Diagnostics provides remote dealer-level diagnostic, coding and programming support to workshops, bodyshops and fleet operators across the UK and Ireland.
Using our remote diagnostic equipment, many advanced procedures can be carried out without the vehicle having to be transported to a main dealer.
Our remote support includes dealer-level diagnostics, ECU and module programming, vehicle coding and configuration, software updates, component replacement programming, Secure Gateway access and manufacturer-level fault investigation.
For a fleet operator, keeping vehicles on the road is critical.
When a workshop reaches the limits of its aftermarket diagnostic equipment, the traditional solution is often to book the vehicle into a franchised dealer. This can mean additional transport costs, recovery charges, dealer booking lead times and, most importantly, a vehicle sitting off the road.
Complete Diagnostics allows specialist technical support to be delivered remotely while the vehicle remains with your chosen repairer.
Modern fleets often contain vehicles from many different manufacturers.
Rather than managing diagnostic requirements through multiple franchised dealer networks, Complete Diagnostics provides a single point of contact for remote diagnostic, coding and programming support across a wide range of vehicle manufacturers.
This is particularly valuable for larger mixed fleets where maintaining manufacturer-level capability across every brand would otherwise require significant investment in equipment, software subscriptions and technical training.
Fleet operators often already have established relationships with trusted independent garages, bodyshops and maintenance providers.
Complete Diagnostics works alongside these existing suppliers rather than replacing them.
Your workshop carries out the physical repair while our technicians provide the specialist remote diagnostic, coding or programming capability required to complete the job.
This enables your existing repair network to complete a wider range of work in-house.
There will always be occasions when a vehicle needs to visit a franchised dealer. However, dealer referral shouldn’t be necessary simply because your chosen repairer doesn’t have access to a particular manufacturer diagnostic platform.
Remote diagnostics can significantly extend the technical capabilities available to independent workshops and fleet maintenance providers.
That can mean fewer unnecessary dealer referrals, reduced administration and, crucially, less vehicle downtime.
Complete Diagnostics supports a broad range of vehicle manufacturers, making the service particularly suited to mixed fleets containing cars and light commercial vehicles from multiple brands.
As vehicle technology becomes increasingly software-driven, access to coding, programming and manufacturer-level diagnostics is becoming an essential part of modern fleet maintenance.
Modern accident repairs increasingly require diagnostic intervention.
Replacement components such as headlights, cameras, radar modules, ECUs, control modules and other electronic systems can require coding, programming or calibration before the vehicle can be returned to service.
Complete Diagnostics can provide this specialist support remotely, helping bodyshops complete repairs efficiently and potentially reducing vehicle key-to-key times.
Whether you operate a regional fleet, manage vehicles nationally or work with a network of approved repairers, Complete Diagnostics can provide a scalable remote diagnostic solution.
Multiple repair locations can access the same specialist technical resource without each location having to invest independently in manufacturer diagnostic equipment, subscriptions and specialist personnel.
Complete Diagnostics already provides remote diagnostic support to more than 600 garages and bodyshops across the UK and Ireland.
Our objective is straightforward: help repairers complete more work themselves, reduce unnecessary dealer referrals and get vehicles back on the road as quickly as possible.
For fleet operators, that means reduced downtime, greater repair flexibility and better control over vehicle maintenance costs.
If you operate a fleet, manage a national repair network or oversee vehicle maintenance across multiple locations, speak to Complete Diagnostics about how remote dealer-level diagnostics could integrate with your existing maintenance operation.

Electric vehicles are now a major part of the used car market — but one of the biggest challenges for forecourts, dealers and buyers alike remains battery health. Unlike traditional combustion vehicles, the condition of an EV’s high-voltage battery has a huge impact on value, range and long-term reliability. That’s why providing transparent, data-driven battery health reporting isn’t just a “nice to have” — it’s becoming essential in today’s EV resale landscape.
Enter the Complete Diagnostics Remote Coding & Diagnostic Tool, capable of performing high-voltage battery tests remotely and producing a clear, professional certificate in under 10 minutes — right from the forecourt or workshop.
Battery condition is now the top consideration for many EV buyers — often even more important than service history or mileage alone. Tools like the Complete Diagnostics Remote EV Battery Health Tester show that buyers are demanding certified State of Health (SoH) information up front, before they commit to a purchase.
Without this data, forecourts are forced to guess at an EV’s residual value. That uncertainty can slow sales, reduce margins and leave buyers feeling unsure about their investment. With an independent, rapid battery health assessment, you instantly eliminate those concerns — and position your site as a trusted destination for quality EVs.
With the Complete Diagnostics tool, dealers, workshops and forecourt teams can:
This capability means your business can produce certified EV battery health reports as part of the sales process, adding transparency for buyers and giving your forecourt a competitive edge.
Just as independent battery health reports are rapidly becoming a standard expectation in the EV resale market, your customers will see the value in clear, concise documentation that explains battery condition in plain terms. Certified battery tests help:
Reduce “range anxiety” concerns for buyers Increase conversion rates on EV stock Improve pricing accuracy and profit margins Enhance transparency and trust throughout the sales process
With EV buyers increasingly seeking certainty — particularly around expensive battery packs — providing a certified assessment built on real vehicle data is a powerful sales signal.

With many vehicles integrating their power steering modules as part of the steering rack assembly, replacing a steering rack can now involve much more than adjusting wheel alignment! When a new power steering rack is fitted the electronic steering assistance modules will require programming and configuring to the vehicle. Please note that some manufaturers require the QR code or barcode information from the steering rack itself, we always advise to take a photo of these labels prior to fitting the replacement part.
Using the Complete Diagnostics remote coding tool, we can programme replacement steering assistance modules/electronic power steering racks to the vehicle without needing to visit the main dealers with the car/van. The very latest DoIP vehicles are also covered by our services ensuring Jaguar Land Rover vehicles and many other brands can still be completed. Any of the required steering angle resets can also be performed if for example you have not needed to replace the entire steering rack assembly.

Replacement Headlight Programming
With modern vehicles constantly increasing in complexity, even basic accident repairs such as replacing a headlight assembly now requires diagnostic coding to enable functionality. We offer remote programming for replacement headlight assemblies on over 130 different vehicles including – Volvo, Ford, BMW, Volkswagen Audi Group and Mercedes Benz. Often to be able to programme these parts requires a visit to the dealers – we can complete these remotely with our remote coding tool, greatly improving the efficiency of the repair process. Many manufacturers now place a QR code on the label of the headlight or a ‘code’ that is required to be input to start the coding process, simply send this to us when requested during the connection via our web portal and we will do the rest.

We will perform an OTA (“Over The Air”) update on all Complete Diagnostics FD remotes. During this update, new functionality will be added regarding the front LEDs of the Complete Diagnostics FD remotes and the update process.
It often happens that when a remote is updating, there has been no clear indication that the remote is performing an update. To solve this problem we introduce the beeper and the blue front LEDs.
A blue front LED and a short beep indicate that the remote is performing an update. It is then important not to disconnect the remote from the car or the internet to prevent the remote from getting stuck in an update.
The update process takes an average of 1-2 minutes (depending on the speed of your internet connection). The length of the update process depends on how regularly you use the remote. It can happen that a remote is updating for a longer period of time because the remote has not been used for a long time. If the update is done correctly, the blue LEDs will return to their original green color.
So if you encounter the blue LEDs and the beeper while using the Complete Diagnostics FD remote, it is important to patiently wait for the update to complete.
