What Causes the Engine Exclamation Warning Light to Illuminate?
1 Answers
Engine exclamation warning light illuminates due to dry dual-clutch transmission clutch overheating or engine oil pressure sensor malfunction. Dry dual-clutch transmission clutch overheating: Elevated engine and coolant temperatures impair transmission cooling. Radiator grille blockage; thermostat sticking. Transmission clutch slippage generates excessive heat. Insufficient flow in transmission cooling oil circuit. Engine oil pressure sensor malfunction: Persistently low oil pressure or sudden pressure drop. Causes of low oil pressure fall into two categories: 1) obstructed oil passages or inadequate supply upstream of the sensor; 2) excessive oil leakage downstream of the sensor. Sudden pressure drops typically indicate severe oil leaks, such as missing pipe plugs, cracked oil galleries, etc.
