What is the carbon deposit in the exhaust pipe of Land Rover Freelander 2?

1. At present, there are only two methods to remove carbon deposits in repair shops. One is to use the disassembly-free cleaning method when the carbon deposition is not serious, and clean by adding special cleaning agent liquid. Second, if the carbon deposition is serious, the valve and cylinder block should be cleaned by uncovering the cylinder head.

Second, one is to drive by yourself and take some preventive and remedial measures to minimize carbon deposition:

1, using clean fuel conforming to the label;

2. Cultivate good driving habits and shift gears by hand over 2000 rpm;

3. Raise the speed at regular intervals, so that the engine can run at high speed to remove slight carbon deposit.
