Engine Intelligence

Audi / VW / Porsche 3.0 V6 TDI (A6/A7 C7, Touareg 7P, Macan, Cayenne — CR piezo) CKVB

Common symptoms

Uneven or unstable idle
Ticking or knocking from the engine
Hard or intermittent starting
Hissing / chuffing with exhaust smell when an injector washer leaks
Reduced power, hesitation or limp mode with warning lights

Documented failure modes

Piezo injector electrical faults logging group supply-voltage codes
Injector correction values drifting out of range as the piezo stack ages
Injector sealing washer leaks allowing combustion blow-by around the injector

Diagnostic guidance

Compare injector balance / correction values across all six cylinders — an outlier identifies the failing unit
On group supply-voltage codes, check the injector harness and connectors before replacing hardware
Check return flow to identify a hydraulically defective injector
Injector coding is required after fitting — follow the manufacturer procedure
