Audi Q5 Slight Shaking During Cold Start?
1 Answers
The reasons for the slight shaking of an Audi Q5 during cold start are as follows: 1. Insufficient engine temperature. When starting a cold vehicle, the temperature inside the engine is similar to the surrounding environment, which is not suitable for engine operation. In low-temperature conditions, fuel atomization is poor, leading to reduced ignition energy, thereby affecting performance and causing the car to shake. 2. Carbon buildup in the engine. Carbon buildup is one of the significant reasons for shaking during cold starts. During daily driving, different driving environments and habits can lead to varying degrees of carbon deposits. Excessive carbon buildup on the valves and intake manifold can make cold starts difficult and may result in insufficient power or even stalling while driving.
