Frequently asked questions
Can an AdBlue fault on the Peugeot 308 be solved with software?
In most cases, yes. For the Peugeot 308, fault memory is read and the ECU identified first; a matching AdBlue/SCR software solution is applied with the original software backed up. Suitability is checked per engine and ECU version.
What about inspection after an AdBlue delete?
It is an intervention on the emission system and is offered only for uses permitted by law. Inspection and road compliance remain the owner's responsibility.
Does the countdown stop?
Once the system is disabled the countdown and the no-start lockout are removed and the vehicle can run again.
Should I try repairing it first?
If the vehicle will stay on the road, yes. Most faults come from a single part (pump, heater, NOx sensor); we diagnose first and tell you the repair cost.
Does the hardware have to come off?
The software side is enough; the tank and pump can stay in place. Physical removal is optional.
