What a diagnostic check includes
A diagnostic check at D&B Automotive starts with listening to your concerns, then connecting professional diagnostic equipment to your car’s on board systems.
We scan all control units for stored and live faults, check sensor readings and carry out visual inspections.
Our technicians may also perform test drives or smoke tests where required. You receive a clear report of findings, advice on urgent and future repairs, and a written estimate before any work begins.
Where needed we also test related mechanical parts and record results.

How long a diagnostic takes
The time a diagnostic takes depends on the type of fault and how easy it is to reproduce. A basic code read and health check can often be completed within an hour, including a short road test and report. Intermittent faults, wiring problems or complex issues may need more investigation, such as extended test drives, smoke testing or access to hidden components.
We will explain the likely stages of testing when you book, such as initial scans, road tests and deeper circuit checks. If extra time is required, we keep you updated and get approval. Many checks can be completed the same day, with results discussed in person or by phone. Any expected delays are explained clearly at the outset.
