Poseidon Posted August 18, 2021 Report Share Posted August 18, 2021 bmw e46 m54b30 Rinse tank (purge) error or defective. Purge is active from 1800rpm on the link g4 + I currently have the problem when I drive off where I come over the 1800upm that the lambda goes down from 1.00 to 0.68 - 0.70 and the engine stutters. Purge valve works fine. I disconnect the line to the tank, it just draws a little more air. If I plug in the line, it becomes very fat again Quote Link to comment Share on other sites More sharing options...
