Engine Diagnostics
Dealer-level fault finding, without the guesswork - across Weston-super-Mare, Clevedon, Portishead, Nailsea and the wider North Somerset area.
Overview
What this covers.
A warning light never tells you the whole story - it only tells you where to start looking. Our engine diagnostics combine dealer-level diagnostic equipment with genuine mechanical experience, so instead of swapping parts and hoping, we trace the fault to its true root cause.
From intermittent misfires and flat spots to emissions faults and sensor failures, we test systematically, explain what we find in plain English, and quote before any repair work begins. Drivers across Weston-super-Mare, Clevedon, Portishead and Nailsea come to us because we find the fault the first time.

Common questions
Before you book.
Can you just clear the code for me?
Clearing a code without fixing the cause only hides the symptom. We diagnose the underlying fault properly, then the light stays off for the right reason.
My fault is intermittent - can you still find it?
Often yes. We store freeze-frame data, test live, and where needed keep the car under observation while reproducing the conditions that trigger the fault.
How long does a diagnostic session take?
Most diagnostic sessions are completed within a couple of hours. Complex or intermittent faults can take longer, and we will keep you informed throughout.
