CNHA uses advanced Bosch piezo injectors requiring ODIS for coding. Unlike older generations, CNHA injector codes are stored in the ECU and must be transferred correctly. Professional installation with genuine diagnostic equipment is strongly recommended.
The AUDI CNHA engine requires injectors calibrated to specific flow rates and spray patterns. At Remanufactured Injector, our technicians test every CNHA injector to original manufacturer specifications using OEM-grade diagnostic equipment.
AUDI CNHA Injector Cost
AUDI CNHA diesel injector replacement cost UK ranges from £150 to £400 per injector for remanufactured units. The CNHA engine uses precision-calibrated injectors that require exact flow rates and spray patterns.
Testing CNHA injectors costs £20 each and confirms which specific injector is causing problems. Common CNHA symptoms like rough idle, black smoke, or poor fuel economy often stem from just one faulty injector.
Our remanufactured CNHA injectors are tested to AUDI original specifications with new seals, nozzles, and 12-month warranty included. Same performance as new, significantly lower cost.

AUDI CNHA Injector FAQs

Other AUDI Engine Codes
Common Problems with AUDI CNHA Injectors
The AUDI CNHA engine commonly experiences injector issues related to solenoid valve wear causing injection timing drift, nozzle tip carbon deposits from DPF regeneration cycles, and return line seal failures after 120,000 km. The CNHA Bosch injectors are generally reliable but sensitive to fuel quality. Professional testing identifies exactly which injector is failing before expensive replacements.
Symptoms of Failing AUDI CNHA Injectors
Failing AUDI CNHA injectors typically cause: rough idle or vibration at standstill, excessive white or black smoke on startup, poor acceleration and "limp mode" activation, increased fuel consumption (10-20% worse), engine warning light with P0201-P0204 fault codes, hard starting especially when cold, and diesel knock or rattling sounds. VW/Audi CNHA engines commonly display cold start hesitation first. If you notice any of these symptoms, professional injector testing (£20/injector) can confirm the diagnosis before committing to replacement.
