Car Diagnostics - Waterlooville

A warning light on the dashboard can mean almost anything, from a minor sensor fault to something that needs urgent attention. The only way to know for certain is a proper diagnostic investigation, carried out with the right equipment by someone who knows how to interpret the results.

At Collison Motoring Services, we use Bosch KTS and Opus diagnostic systems, two of the most capable platforms available to independent garages, and our technicians are trained to go beyond simply reading fault codes. We investigate the underlying cause, because a code tells you where to look, not necessarily what’s wrong.

Our diagnostic services cover:

Engine management and warning light investigation
ABS, traction control, and stability system faults
Airbag and SRS system faults
Transmission and gearbox fault codes
Emissions system faults including DPF and EGR
Hybrid and electric vehicle system diagnostics
Software updates and ECU coding

What happens during a diagnostic check?

We connect to your vehicle’s OBD system, read any stored fault codes, and review live data where relevant. We’ll then talk you through what we’ve found in plain language and give you a clear quote for any recommended work before anything is started. No jargon, no pressure.

Drivers come to us for diagnostic work from across Waterlooville and the wider area, often having had a warning light dismissed or misdiagnosed elsewhere. Getting it right first time saves money and avoids repeat visits. If a light has come on, don’t ignore it. Book a diagnostic and let’s find out what’s actually going on.

As a Bosch Service network member, a HEVRA-approved EV and hybrid specialist, and an IMI-affiliated garage, we’re independently verified to meet recognised standards across the board. For you, that means confidence in the quality of the work, without having to just take our word for it.
