2339622 MX-13 Euro 6 EGR valve: symptoms, fault codes and OEM cross references.
Main MX-13 Euro 6 EGR valve interchange group. It combines repeated reports for 2339622 and linked replacements where symptoms are soot blocking, position errors, failed regens and derate.
OEM report needs verification
This number appears in duplicated or conflicting report groups. Confirm by VIN, engine type, installed connector and photos before quoting or fitting.
- Several source reports list 2104971 and 2128867 in both EGR and BPV contexts; keep an ambiguity warning for exact OEM lookup.
What drivers and mechanics usually notice.
These are practical, workshop-style symptom phrases written for search and support conversations. They are not a substitute for live diagnostic data.
Power derate or limp mode
EGR valve stuck open or stuck closed in diagnostic software
Rough idle, hunting or surging at cruise
Black smoke when pulling away or backing under a trailer
Failed regeneration and high DPF differential pressure
Coolant loss with no visible external leak
AdBlue or NOx after-cat secondary faults from incorrect EGR rate
Why 2339622 usually fails
- Carbon and soot cake the EGR valve plate, shaft and valve seat.
- Condensation and oil mist form acidic sludge after the EGR cooler.
- Motor gearbox wears from continuous modulation and high resistance.
- Coolant leakage through the cooler or valve interface corrodes electronics and accelerates sludge build-up.
- Position sensor drift causes commanded-versus-actual mismatch.
Before replacing the part
- Compare commanded EGR position against actual feedback during key-on sweep and during a road test.
- Inspect for coolant traces inside EGR passages if white smoke or unexplained coolant loss is reported.
- Do not treat every NOx or AdBlue fault as SCR-only; incorrect EGR rate can trigger secondary aftertreatment faults.
