If you’ve just changed the oil or had your Ford Fiesta serviced, but the wrench warning light or service reminder is still showing on your dash, don’t worry — it’s easy to reset it yourself in just a few steps. Whether you’ve got a petrol Mk7 or a newer mild hybrid Mk8, this guide will walk you through how to reset the maintenance light on the Ford Fiesta from 2008 to 2023.
We’ll also explain what the warning means and why it comes on, so you’re not just clearing the light but understanding what it’s telling you, too.
What does the maintenance light on a Ford Fiesta mean?
The maintenance or service light on a Ford Fiesta usually shows up as:
A small spanner (wrench) icon
A message saying ‘Service due’ or ‘Oil change required’
This light appears based on the car’s onboard service interval tracking system. It doesn’t always mean something is wrong — just that it’s time for scheduled maintenance. Most newer Fiestas trigger this light every 10,000 to 12,500 miles or after 12 months, whichever comes first.
When should you reset it?
Only reset the service reminder after you’ve completed an oil change or had the car properly serviced. If you reset it without doing the work, you risk forgetting when maintenance is actually due — and that could cause bigger problems down the line.
Resetting the maintenance light: Ford Fiesta Mk7 (2008–2017)
This applies to petrol and diesel versions, including the popular 1.25L, 1.4 TDCi, and 1.6 models.
Steps:
Turn the ignition key to position II — don’t start the engine.
Press and hold the accelerator and brake pedals at the same time.
Keep both pedals held down for around 15 to 25 seconds.
The spanner icon will flash, and you’ll see a message like ‘Service: reset complete’ on the screen.
Release the pedals, turn off the ignition, then restart the car to check the light has cleared.
Resetting the service light: Ford Fiesta Mk8 (2017–2023)
This applies to newer Fiestas including the EcoBoost 1.0L, ST-Line, and mild-hybrid versions
Steps:
Get in and close all doors.
Press the ignition button once (or turn key to position II) so the dash lights up — but don’t start the engine.
Press and hold the accelerator and brake pedals at the same time.
Wait for around 15 seconds until you see ‘Service: reset complete’ or a flashing spanner.
Release the pedals and switch the car off.
Start the engine to confirm the service light has disappeared.
⚠️ Note: On some facelifted 2022–2023 Fiesta models with the digital dash, you may need to access the service menu through the touchscreen settings. Look under “Vehicle Settings > Information > Oil Life Reset”.
Why does the spanner light come back on?
If the spanner light returns immediately after you’ve reset it:
Double-check that the oil change was properly done
Make sure both pedals are pressed fully
On Mk8 models, try with the ignition on but engine off, not just key position II
Still stuck? A faulty oil life sensor or outdated software update may be to blame; in that case, a quick diagnostic scan or a visit to the dealer might be necessary.
Final word
The Ford Fiesta is one of the UK’s best-selling cars — and for good reason. It’s easy to maintain, cheap to run, and incredibly DIY-friendly. Resetting the service light is a simple but essential step in keeping on top of your Fiesta’s maintenance, especially if you do your own oil changes or use an independent garage.
