Engine warnings are the lights drivers see most. The scanner reads them, tells you what they mean, and turns them off once the fault is fixed.

Engine and emissions systems only. It doesn't program keys or reset ABS or airbag lights. Some tests, like EVAP, depend on what your car supports.
Will it work with my car?
Since 2001 for petrol and 2004 for diesel, every car sold in the EU has the same 16-pin OBD2 port, whatever the brand. Pick your brand, fuel and year to check.
Look for the 16-pin port under the dashboard on the driver's side.
Pay once, check whenever you want
Many garages charge for every diagnostic check, often more than this scanner costs. Buy it once and use it for every warning light after this one.

Questions
Will it work with my car?
If it is a petrol car from 2001 or a diesel from 2004 sold in the EU, yes. These cars all share the same OBD2 port and code system, whatever the brand.
Can it save me a trip to the garage?
Often, yes. Many warning lights come from small things, like a loose fuel cap, that you can fix yourself and then clear. When it is something bigger, you go to the garage knowing the problem, so you only pay for the repair.
Is it safe to clear the warning light?
Clear codes only after the fault is fixed. If the problem is still there, the light comes back on.
Do I need a phone or an app?
No. Everything shows on the scanner's own screen.
How fast is delivery?
Fast and free. Orders ship from a warehouse in the EU with tracking and usually arrive in 4 to 9 business days, often sooner. You get the tracking number by email.
Can I return it?
Yes. You can return it within 14 days of delivery.
Next time the light comes on, you'll know why.
