P219E

Cylinder #3 Imbalance Error

P219E is a generic OBD-II powertrain diagnostic trouble code: Cylinder #3 Imbalance Error. It is logged by the engine control unit when the scr/adblue monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.

Disabling P219E in software

RaceTune can permanently disable P219E — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.

Permanent

The monitor is disabled in the ECU itself — not just cleared. It cannot return.

Tailored to your file

Each patch is matched to your specific software version — never a one-size-fits-all file.

Reversible

The original file is always preserved. Reflash the stock to return the ECU to factory state.

Software modifications affect emissions compliance and are not road-legal in many jurisdictions. RaceTune service files are intended for motorsport, off-road, and export use.
