30C1 on teie BMW mällu salvestatud rike (ISTA rikkekood, mitte standardne OBD-II P-kood).
Mida see tähendab: DME — engine oil-pressure control (static). The engine management sees the oil-pressure regulation out of range. First check the oil level and condition — topping up or an oil + filter change fixes a large share of cases. If it persists, verify the oil-pressure sensor against a gauge (replace if off); in some cases it points to the oil pump or timing-chain wear. Don't ignore oil-pressure faults — have it checked.
