    Hello, some time ago I bought Renault Laguna 2 1.9Dci 2003. for commuting to work, the problem was with power up to 2000,000. rpm was sluggish and from 2800 thousand again there was a decrease in power and a high combustion of about 9ltr / 100km (the car was burning from the shot and it did not kick and went evenly).

    I was on the computer zero mistakes !!!

    I wyłściłem Egr (was slightly dirty)
    I have exhausted the gasoline extractor flow meter and the boost pressure sensor, I have thoroughly poured into it a few times the above petrol ... the effect of the car works as I need to recommend all these treatments because as I read about used injections of turbines and ending engines HAIR WERE HEAT! !! additionally, please pay attention to the leakage detector !!!
    Simple operation and lasts from 30 minutes
    I greet you cheerfully

    Hello or turbo efficient, control turob geometry is about?

    After my treatment, the turbo works differently: it is now efficient, you can hear it very clearly from the lower revolutions working (pumping suction) earlier it was not suspected that the pressure sensor was guilty because it was dirty with oil

Topic summary

The discussion revolves around a Renault Laguna 2 1.9 Dci (2003) experiencing power loss at 2000 RPM and high fuel consumption of approximately 9 liters per 100 km. The owner reported sluggish performance below 2000 RPM and a drop in power after 2800 RPM. Diagnostic checks revealed no error codes. The owner cleaned the EGR valve, replaced the fuel flow meter, and addressed a dirty boost pressure sensor, which improved turbo efficiency and overall performance. Other participants suggested checking turbo geometry and confirmed that cleaning the pressure sensor had a positive impact on the vehicle's operation.
