Peugeot Fault Finding
Engine warning light on, an "Engine fault: repair needed" message, or a Peugeot that's reluctant to start? Our Peugeot specialists at our Tarring Road garage in Worthing use Peugeot's own Diagbox diagnostic software and manufacturer data to find the real cause, then explain it clearly and give you a quote before any repair work starts.
Dealer-Level Equipment
Why Choose Cedar Garage for Peugeot Fault Finding?
Getting the diagnosis right first time is what saves you money. Rather than replacing parts in the hope of curing a fault, our Peugeot fault finding follows a logical test plan, checking live data and testing the sensors, wiring and components involved, so you only pay for the parts that actually fix the car. Our technicians work on Peugeots every day, from the 108, 208 and 308 to the 2008, 3008, 5008, 508 and RCZ to the Partner, Rifter, Expert and Boxer, so we know the faults these cars are prone to.
With Peugeot's Diagbox software and manufacturer technical information, you get the same level of diagnosis as the main dealer, with the personal service of an independent garage. We can collect your Peugeot and return it when the work is done, or provide a hire car while it's with us, and we'll never spend more of your money without your approval.

Frequently Asked Questions
Peugeot Fault Finding FAQs
What does Peugeot fault finding involve?
We use Peugeot's own diagnostic software to read any fault codes, then test the parts involved to find the real cause. We'll explain what's wrong and give you a quote before any work goes ahead.
How much does Peugeot fault finding cost?
We start with an initial fault finding check at a fixed price, which we'll confirm when you book. If the fault needs more time to track down, we'll always ask you first.
What does "Engine fault: repair needed" mean on my Peugeot?
It means your Peugeot has spotted a fault with the engine, but the message alone doesn't tell you what. Book in for fault finding and we'll find the actual cause, rather than just clearing the warning.
What does "Antipollution fault" mean on my Peugeot?
It means your Peugeot has spotted a problem that could affect its emissions. Left alone, it can lead to reduced power or an MOT fail, so book in for fault finding and we'll find the cause.
Why is my Peugeot showing an AdBlue warning?
It may just need topping up, but it's often a fault in the system. If you see a countdown such as "Starting impossible", book in quickly, as the car won't restart once it reaches zero.
Can I keep driving with the engine warning light on?
If the light is steady and the car drives normally, you can usually drive for a short time, but book it in soon. If it's flashing or the car loses power, stop driving and give us a call.
Why won't my Peugeot start?
It could be a flat battery, a starter motor fault, a fuel problem or the car not recognising the key. Give us a call and we'll talk you through the options.
Why is my Peugeot hard to start from cold?
There are a few possible causes, from a fuel problem to a faulty sensor. Book in for fault finding and we'll find out what's causing it.
Why does my Peugeot hesitate or lose power when accelerating?
It could be an air leak, a faulty sensor or a misfire, as they can all feel similar. Book in for fault finding and we'll road test your Peugeot to find the cause.
Why doesn't the boot or boot light work properly on my Peugeot?
It's often a wiring or switch fault in the boot lid. Book in for fault finding and we'll find what's failed and repair it.
Do I need the main dealer for software updates or programming?
No. We use Peugeot's Diagbox software for updates, programming and coding, so your Peugeot can be diagnosed, fixed and programmed in one place.
How long does Peugeot fault finding take?
Many faults are found during the initial check, while faults that come and go can take longer. We'll tell you what to expect when you book and keep you updated.
