Warning Light Diagnosis
Also called dashboard warning light
Warning light diagnosis covers any light on your dashboard, not only the engine light. Each belongs to a different system with its own control unit and its own codes. We identify the light, scan the relevant module, check the live values and tell you how urgent it is. Oil pressure and temperature lights mean stop now; an ABS light means reduced braking assistance but the brakes still work. This is diagnosis and advice, with the repair quoted separately.
Signs you need this
- A warning light you do not recognise has appeared
- Several lights have come on at the same time
- A light appears only at certain speeds or temperatures
- A warning message on the information display
- A light stays on after a repair was carried out
Not all of these have to be present, and one of them on its own can mean something else entirely. That is what the diagnosis is for.
What the job includes
- Identification of exactly which warning is showing
- Scan of the relevant control module, plus related modules
- Live data checked for the system concerned
- Basic mechanical checks such as fluid level or a pressure test where relevant
- Clear urgency assessment: stop now, drive carefully, or monitor
- Written findings and a separate repair quote
How we do it
Identify the warning
We confirm the exact symbol or message, since lights that look similar belong to completely different systems.
Check the basics first
For oil, temperature and brake warnings, fluid levels and pressures are checked before any electronic diagnosis.
Scan the right module
The relevant control unit is scanned along with related modules, as one fault can trigger warnings in several.
Verify with live data
Live values are compared against expected readings to confirm the fault is real and not a sensor reporting wrongly.
Advise on urgency
You are told plainly whether to stop driving, drive carefully to a workshop, or monitor it, and what repair is needed.
How we work
The same on every job, which is why we can write it down.
Diagnosis before quote
We find the fault first. A price given over the phone for a noise nobody has heard is a guess.
The price is agreed first
You approve the work and the cost before a spanner is picked up. Extra work means another call.
Parts you can check
We tell you whether a part is genuine, OEM, aftermarket or used, and what each one costs.
Old parts returned
Ask and we will hand back whatever we replaced. It is the simplest proof that the job was done.

Fill this in and a person will call you back to confirm the time and the price. Only your name and one way to reach you are required.
You send this
Takes a minute. No payment, no obligation.
We call you
To confirm the car, the time and the location.
Tell us the car and the symptom
