When it's time for a diagnostic check

We plug in, read the fault codes properly, and tell you what's actually wrong.

Warning light

Any dashboard light you don't recognise or can't clear.

Limp mode

The engine holds back power for no obvious reason.

Unusual noise or feel

We diagnose it properly

We connect diagnostic equipment directly to your vehicle's ECU and read the fault codes stored, then match them against the symptoms you've described. You get a clear answer on what's wrong and what it'll cost to fix, before any further work goes ahead.

No unnecessary parts

A diagnostic check tells us exactly what's needed, so we don't replace parts without good reason. If a software fix solves it, that's what we'll recommend.

Frequently asked questions

How long does a diagnostic check take?
Most checks take well under an hour, done wherever your car already is.
Will you fix the fault on the same visit?
Often, yes, if it's something we can resolve on site. If it needs parts or a different service, we'll quote you before booking anything further.
Do you charge for the diagnostic itself?
Every quote is free. Get in touch and we'll talk through the cost before anything's booked in.
What if the warning light comes back?
If a fault recurs shortly after a diagnostic, get in touch and we'll take another look.
Can you diagnose intermittent faults?
Yes, though an intermittent fault can take longer to pin down than one that's constantly present. We'll be upfront if a fault needs monitoring over more than one visit.
Do you clear fault codes without fixing the cause?
No. Clearing a code without fixing what caused it just means the light comes back. We diagnose and explain the actual cause before recommending anything.
