i am having problems with my laguna 1.9dci around 2000 revs the car goes into kangaroo mode and lots of black smoke comes from the exhaust , i have read a lot on the egr valves and tried cleaning it out but problem continues any ideas.
Hi, You didn`t say if you cleaned the two holes which connect the egr chamber to the one with the throttle damper on. I had same problem went and cleaned the egr valve found it to be clean, then found that the two holes were caked in carbon. Cleaned them out and upto now running nice and smooth. Hope this helps.
