How do you get rid of soot on the EGR?

Cleaning The EGR naturally puts exhaust soot into the intake which must be cleaned out. It mixes with oily crankcase vapors from the crankcase ventilation (CCV) and can form a buildup. The introduction of ULSD ultra low sulfur diesel has reportedly decreased the amount of soot buildup.

What happens if you don’t clean your EGR cycle?

This is also a good time to clean the EGR cooler, the round cylinder behind the intake manifold. Some people use a EGR block off plate to greatly reduce any future carbon buildup in the intake. Disabling or reducing the EGR cycling will increase emissions and could cause a check engine light to appear.

How do I clean the carbon buildup from my EGR valve?

If the amount of carbon buildup is not excessive, and the car runs good, you’re done. Put the intake hose back on, hook up the EGR valve vacuum hose and double-check that the shut-down flap operates freely, and test the flap with a vacuum pump attached at the actuator.

Are there any problems with carbon plugging in a TDI?

With all that good, there is a maintenance problem that has taken a toll on the low cost of operating a TDI, and that is carbon plugging of the intake system. This problem has presented itself on many different years and models of the TDI, with the only real connection being the EGR system.
