What P10DF means on specific makes
BMW / Mini CAUTION
DISA (intake manifold flap/adjuster) issue. NOTE: most DISA faults appear as native BMW codes (e.g. '2787'/hex) read by ISTA, or surface as lean/torque codes on a generic scanner; a clean SAE 'P1' for DISA is not standardized across years.
- DISA valve flap/pivot worn or O-ring failed ($80-200)
- DISA adjuster motor failed
- Broken DISA flap (can drop debris into the engine - inspect)
Check first: On M54/N52 inspect the DISA O-ring and that the flap is intact and not loose — a broken flap is a serious ingestion risk.
