What we do

We scan the vehicle, read the fault codes, and diagnose the real cause, then quote the fix and explain it plainly, no jargon. A code is a starting point, not the whole answer, so we test properly before telling you what's wrong.

How much does it cost?

A diagnostic fee applies, and we put it toward the repair if you go ahead. We quote any repair before we start.
