We explain what’s needed, give options, and quote before any extra work.

Diagnostics FAQs
Can you diagnose a car that won’t start?
Yes — we can test battery/charging, starter signals, scan for immobiliser/fault codes and trace the cause.
Will you clear the warning light?
We can clear codes after checks, but if the fault is still present the light may return — fixing the root cause is key.
Do you fit parts the same day?
Sometimes, depending on the fault and parts availability. If not, we’ll quote and book you in quickly.
