Assessment
Emissions assessment is the booking route for AdBlue/SCR warning messages, NOx faults, DPF-related symptoms and countdown enquiries before repair or software work is agreed.
Assessment, repair and software boundary
AdBlue solution is £350, with emissions assessment and repair kept separate.
AdBlue solution is a tuning/software route for suitable vehicles where the use case is lawful. If the vehicle has warning lights, countdowns or an unclear SCR/NOx fault, the correct first booking is emissions assessment.
£350 AdBlue solution
The AdBlue solution is £350 including VAT where the vehicle and use case are suitable. Emissions assessment is a separate diagnostic booking used when the workshop needs to confirm the fault evidence before repair, cleaner support or software work is agreed.
Three separate routes
Assessment first. Repair where required. Software only where lawful.
The right answer depends on how the vehicle is used and what has actually failed. PPG will not force every AdBlue warning into the same box.
Road-Use Repair
For cars and vans used on public roads, the correct route is compliant diagnosis and repair: NOx sensors, pump, injector, tank, wiring, crystallisation and SCR faults checked properly.
Software Services
For lawful non-road or exempt use cases, a permanent AdBlue/SCR software service can be discussed separately after the vehicle and use case have been assessed.
Common faults
AdBlue warnings often look simple on the dash, but the cause can sit anywhere across the SCR system.
Countdowns
- No-start countdown or mileage countdown warnings
- SCR efficiency codes after previous parts have been fitted
- Recurring warnings after topping up AdBlue
Sensors & Dosing
- NOx sensor plausibility or poor live readings
- Dosing injector faults or blocked dosing lines
- AdBlue quality, level or tank-signal issues
Hardware & Wiring
- AdBlue pump pressure, tank heater or module faults
- Wiring, fuse, relay, CAN communication faults
- Crystallisation build-up around dosing components
The PPG process
Strong result, clear decision, no dressed-up guess.
The vehicle decides the route. PPG checks the fault evidence, explains the legal boundary and confirms the ECU state after repair or software work.
Scan
Fault codes, live data and the actual dashboard warning are reviewed.
Check
NOx, pump, injector, wiring, dosing and SCR behaviour are considered where supported.
Decide
PPG explains whether repair or a lawful permanent route is the correct answer.
Confirm
After repair or software work, a post-scan checks the ECU state and remaining faults.
Permanent fix where lawful
Some vehicles keep eating parts, counting down or returning with the same SCR fault.
Where the use case is lawful, a permanent software solution can take the AdBlue system out of the equation.
Suitable Use Cases
- Off-road vehicles and private-land use cases
- Export vehicles or specialist non-road applications
- Motorsport, plant, agricultural or exempt use where applicable
File Process
- Vehicle-specific ECU identification before file work
- Original ECU file retained where supported
- Post-scan after the work is complete
Road Vehicles
If the vehicle is used on public roads and must remain emissions compliant, PPG will advise on diagnosis and repair rather than presenting SCR/AdBlue removal as a legal road fix.
Repair still matters
AdBlue software is not a magic repair for broken hardware.
Where the system must stay working, the fault needs fixed properly.
NOx Sensors
Incorrect NOx readings can trigger SCR efficiency faults and countdown warnings even when fluid has been filled.
Crystallisation
Blocked injectors, filler neck deposits and dosing-line build-up can restrict the system and create repeat faults.
Pump & Tank
Pressure, heater, level, quality and pump issues need confirmed before expensive parts or software decisions are made.
Cleaner support
PPG AdBlue anti crystal cleaner is available from the Newtownards workshop.
For crystallisation and deposit problems, PPG also offers its own concentrated AdBlue anti crystal cleaner. If the vehicle already has warnings, countdowns or stored SCR faults, assessment is still recommended first.
20 ml Vial
One vial treats up to 10 litres of AdBlue at the recommended dosage.
System Support
Designed to treat existing crystallisation and help reduce further deposit build-up.
Not A Cover-Up
If the vehicle already has warnings, countdowns or stored SCR faults, assessment is still recommended first.
FAQs
AdBlue and SCR FAQs
Do you offer an AdBlue solution as a permanent fix?
Yes, where the vehicle and use case are legally permitted. For lawful off-road, export, motorsport, plant, agricultural, private-land or exempt use, PPG can discuss a permanent AdBlue/SCR software solution to take the system out of the equation.
Can you do this for road vehicles?
For vehicles used on public roads, emissions equipment must remain compliant. PPG will advise on diagnosis and repair of the AdBlue/SCR system rather than selling SCR/AdBlue removal as a legal road-use fix.
How much is the AdBlue solution?
The AdBlue solution is £350 including VAT where the vehicle and use case are suitable. Emissions assessment is booked separately when the fault cause or correct route needs confirmed first.
Does every AdBlue warning need software?
No. Many warnings need component testing, repair, cleaner support or wiring diagnosis. The correct route depends on the fault evidence.
What checks are carried out first?
Checks can include NOx sensors, pump pressure, dosing injector operation, tank signals, wiring, module communication, fluid condition and stored SCR faults.
