Hello to everyone, I hope I’m right here and someone has already solved this problem. Half a year ago I bought the Laguna II. After a month the turbocharger gave up (injection error lamp lit). Mechanic then found that the AGR was also plugged off. (Probably to get more power?) Then I had the complete Turbo and the AGR replaced. After exchange everything worked out wonderfully. On the way home from the I then drove about 160 km/h on holiday and once again an error message jumps up (injection system lamp). Then I got away from the gas and see the lamp goes out. When I was back the error message went again and again. So in every speed range. Error memory returned: P1125 charge pressure solenoid valve quantity too large. I then changed the charge pressure solenoid valve (which hangs on the left top). Then I actually got the error message only in the lower speed range. So we When the engine is cold, 1/4 gas is enough. Next I changed the charging pressure sensor. Unfortunately, the same thing again. I really don’t know any more. With the mechanic I drove the test and he connected his device. We found out when you accelerated and then let go of the gas the charge pressure deviation jumps briefly to approx. 6000 kPA and then to a 1-digit value. Sincerely.
