Engine Intelligence
VW / Audi / Škoda / SEAT 2.0 TDI CR (EA189 — Golf 6, Passat, Tiguan, T5, Amarok) CBAA
Common symptoms
- Uneven idle, vibration or engine shaking
- Hard starting, especially cold
- Loss of power or hesitation under load
- Black smoke and higher fuel consumption
- Diesel knock / rattle, more noticeable when cold
Documented failure modes
- Injector delivery drift showing as misfire-like running and deviation values out of range
- Injector electrical faults logging cylinder circuit or group codes
- Rail-pressure faults (pump, control valve, leaks) that mimic injector failure
Diagnostic guidance
- Read injector deviation values in diagnostic software — a large outlier identifies the weak unit
- Injector symptoms overlap with dual-mass flywheel and EGR faults on the EA189 — rule them out before replacing hardware
- On group or circuit codes, check the injector harness and connectors first
- Injector coding is required after fitting — follow the manufacturer procedure
Fitment note: EA189 2.0 TDI spans many engine codes and outputs across cars, T5 vans and Amarok, with different Bosch references per application (and the BiTDI uses its own spec) — always match the reference etched on the injector body.
Why this injector?
- Fits the CBAA engine code used in the VW Golf VI and related diesel variants.
- Bosch diesel injector — flow-tested and calibrated on common-rail equipment before despatch.
- Commonly specified when investigating rough idle, injector knock, smoke or poor fuel economy on CBAA engines.
- 12-month warranty, free UK delivery and a £20 refundable core deposit per injector (refunded after we receive and inspect your old unit — return it within 30 days).
