What Causes the Oil Warning Light to Illuminate in a Cayenne 3.6?
1 Answers
Cayenne 3.6 oil warning light illumination may occur due to the following specific reasons: 1. Insufficient oil level: This reduces the oil pump's output or causes air intake, leading to decreased oil pressure. 2. Overheating engine: This can thin the oil, causing excessive leakage through component clearances and resulting in pressure drop. 3. Abnormal oil pump components: Damaged or excessively worn pump parts, or improper assembly causing excessive clearance, may prevent proper oil circulation. 4. Improper clearance between crankshaft and bearings: Incorrect clearance between crankshaft/main bearings (too tight increases oil pressure, too loose decreases it).
