Adblue system
By OE Match
- Porsche 95B.1 Macan S Diesel 3.0L V6 (258Bhp) 2014-18
This OE Match AdBlue injector is a replacement dosing injector used in the SCR emissions system on Porsche 95B Macan Diesel models. It injects AdBlue / diesel exhaust fluid into the exhaust stream to help reduce harmful nitrogen oxide emissions.
Fits:
Porsche 95B Macan S Diesel 3.0L V6 2014 - 2018
Diagram ref no 10
The AdBlue injector sprays a controlled amount of AdBlue into the exhaust system before the SCR catalyst. The fluid reacts with exhaust gases inside the catalyst to convert nitrogen oxides into less harmful nitrogen and water vapour. Correct injector operation is essential for emissions control, engine management performance, and avoiding AdBlue system fault warnings.
Functions
• Injects AdBlue / diesel exhaust fluid into the exhaust system
• Supports SCR catalyst operation
• Helps reduce NOx emissions
• Provides accurate dosing controlled by the engine management system
• Helps maintain correct emissions system performance
• Prevents AdBlue crystallisation issues caused by faulty spray pattern
• OE Match replacement for a failed or blocked original injector
Why Replace This Part?
AdBlue injectors can become blocked, crystallised, contaminated, electrically faulty, or damaged by exhaust heat and age. A failing injector may cause emissions warning lights, AdBlue system faults, poor dosing, failed emissions tests, or limp mode. Replacing the injector helps restore correct SCR operation and keeps the diesel emissions system functioning as intended.
When to replace :
• AdBlue or SCR system warning light is displayed
• Diagnostic fault codes indicate a dosing injector fault
• The injector is blocked, leaking, crystallised, or contaminated
• AdBlue is not being dosed correctly into the exhaust
• The vehicle fails an emissions test due to NOx control issues
• There is crystallised AdBlue residue around the injector or exhaust connection
• The exhaust/SCR system has been serviced or repaired
Where it fits on the car
This injector fits in the exhaust emissions system on Porsche 95B Macan Diesel models. It is installed in the exhaust pipe/SCR dosing position before the SCR catalyst, where it sprays AdBlue into the exhaust stream.

OEMatch Adblue system — Fit, Function, Confidence
AdBlue systems reduce nitrogen oxide (NOx) emissions by dosing a urea solution into the exhaust stream. OEMatch supplies pumps, injectors, tanks, sensors and control modules for Porsche models, with parts chosen and documented to support model-specific repairs and system servicing for diesel and hybrid engines.
Available Types
- AdBlue pumps
- AdBlue injectors
- AdBlue tanks and level sensors
- AdBlue heaters and lines
- SCR control modules
Understanding OEMatch Adblue system
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original adblue system.
OE (Original Equipment) refers to parts matching original specifications for the adblue system and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM adblue system items engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
AdBlue dosing takes place upstream of the SCR catalyst where the injected urea solution converts NOx into nitrogen and water vapour. The system relies on accurate fluid pressure, temperature control and injector flow alongside tank-level sensing and heater elements to prevent crystallisation. OEMatch provides parts and model-specific references to help diagnose faults and restore correct dosing and emissions control across Porsche diesel and hybrid variants.
Benefits Include
- Restores correct SCR dosing to reduce NOx emissions
- Prevents diagnostic faults and system lockouts
- Helps resist crystallisation and chemical degradation
Why Adblue system Wear and Fail
- Crystallised AdBlue deposits that clog injectors or pumps
- Sensor or heater failures within the tank assembly
- Leaking or blocked AdBlue lines and electrical faults in control units
The Importance of Replacing with OEMatch Adblue system
Timely replacement of worn AdBlue components helps maintain emissions compliance, avoids diagnostic errors and supports reliable engine operation. Using correctly specified parts reduces the risk of breakdowns and keeps the SCR system dosing accurately, which is important for regulatory checks and day-to-day performance on Porsche models.
Advantages
- Made to original-spec dimensions for consistent operation
- Compatible with factory sensors and control systems where required
- Available for key Porsche diesel and hybrid models to support targeted repairs
