If you own a Peugeot diesel vehicle in Cambridge, it is only a matter of time before you encounter AdBlue, SCR or NOx related problems. Peugeot vehicles have notoriously unreliable AdBlue systems, and Peugeot have acknowledged some of these flaws by offering warranty repairs on newer vehicles - however most Peugeot's are now too old to be covered by the manufacturer warranty, and Cambridge driver's are facing expensive repair bills when the AdBlue SCR system fails. These issues are frustrating, costly, time-consuming and can even prevent your vehicle from starting.
In this blog, we’ll explain how the AdBlue system works, why Peugeot models are prone to faults, what the repairs typically cost, how you can avoid problems in the first place, and the benefits of an AdBlue delete*. If you’re searching for a Peugeot AdBlue delete in Cambridge, don't skip this must-read article.
Peugeot AdBlue Delete Cambridge - How Does the Peugeot AdBlue System Work?
Peugeot’s AdBlue system is part of the Selective Catalytic Reduction (SCR) process, designed to reduce nitrogen oxide (NOx) emissions from diesel engines. AdBlue is a urea-based fluid that is injected into the exhaust system, breaking down harmful emissions into nitrogen and water. All Peugeot cars and vans that are Euro 6 standard, which is typically from 2016 onwards, will have an AdBlue SCR system which must be operational to meet the intended emissions levels.
One of the biggest headaches for Peugeot owners is the engine no-start countdown. When the AdBlue system detects a serious issue that increases NOx emissions, a warning appears, giving you a limited number of miles before the engine refuses to start. Ignoring these warnings and reaching zero miles, will lead to your Peugeot vehicle being immobilsed and inoperable - and may leave you stranded in an inconvenient or dangerous location.
Peugeot AdBlue Delete Cambridge - Common Peugeot AdBlue Faults & Repair Costs
Unfortunately for Cambridge drivers, Peugeot vehicles are well known for AdBlue related problems. The first signs of something wrong will be a persistent "top up AdBlue" message, emissions related warnings and a flashing spanner symbol on your dashboard. Here are the most common issues:
AdBlue Pump Failure – The AdBlue pump is responsible for building and maintaining pressure inside the AdBlue tank, to enable the urea fluid to be injected into the SCR system. When it fails, you’ll typically see an “Emission Control Fault” warning and a P20E8 fault code. You cannot replace the pump, meaning a new tank unit is required, costing in the range from £800 to £2,000 (depending on the model and the garage doing the repair).
AdBlue Injector Blockage – Over time, crystalised uera deposits can clog the injector and reduce it's effectiveness, leading to reduced AdBlue dosing and increased emissions. You may see a P2049 or a P20EE fault code. Cleaning a blocked injector costs around £100–£250, but does not prevent a future blockage. A replacement injector typically costs up to £250-£500.
Faulty AdBlue Tank Sensor – The tank level sensor often fails, falsely indicating low fluid levels even when topped up. The repair is the same as the pump failure fault, requiring a new tank unit priced between £800 and £2,000.
Contaminated or Poor Quality AdBlue Fluid – Using low-quality AdBlue or contaminants in the tank can damage the entire system. A professional flush and refill costs £100-£200.
Peugeot AdBlue Delete Cambridge - How to Minimise Peugeot AdBlue Problems
Whilst AdBlue faults are inevitable, Peugeot owners in Cambridge can take proactive steps to postpone a costly repair:
Only Use High-Quality AdBlue – Ideally, purchase AdBlue from a dispensing pump at a good quality petrol station.
Top Up Regularly And Don't Ignore The Warnings – Don’t wait for or ignore low-level warnings. Keeping the tank sufficiently filled prevents unnecessary strain on the pump and sensors.
Try To Avoid Short Journeys – Peugeot’s SCR system works best when the engine is fully warmed up. Frequent short trips can accelerate crystallisation in the AdBlue tank or injector.
Consider An AdBlue Delete - To avoid the inconvenience of an engine no-start, Peugeot drivers in Cambridge could opt for an AdBlue delete from Optimal Automotive, which is a software modification to disable the AdBlue functionality from their vehicle - preventing problems from occuring.
