How does Audi clean up carbon deposits most thoroughly?

First, carbon deposition and its causes

Carbon deposition in automobiles is mainly due to insufficient combustion of fuel in the engine. Many unsaturated olefins and colloid components in gasoline will cause residue accumulation in fuel nozzles, throttles, fuel pipes and spark plugs, and form black solid carbon deposition when the engine is at high temperature. Generally speaking, there are two main types of valve/combustion chamber carbon deposit and intake pipe carbon deposit.

Second, the real ways to reduce and clean up carbon deposits are as follows:

1, try to avoid forming bad car habits such as long-term idling and low-speed driving and long-term hot car driving.

2. Try to go to a reliable regular gas station and fill it with high-quality fuel.

3. Don't get into the habit of shifting gears at low speed in order to save fuel.

4, maintenance, about every 20000 kilometers, do a throttle cleaning, if conditions permit, you can do some endoscopes and other projects.

Precautions:

Disassemble and clean the carbon-deposited parts of the engine, but this method will easily lead to a lower sealing level than the original factory, and it will cost thousands of dollars, which will reduce the performance of the car. It's really a sesame and a watermelon. However, if the problem can't be solved without disassembly, please try to go to a 4S shop or a qualified factory for construction.
