good day. my berlingo causes me big problems. according to tüv the exhaust values are not in order. the co content is clearly too high. with increased empty run 6,382%, and in empty run 10,760%. so the engine runs too greased. the following was exchanged: – water temperature sensor – vacuum tube sensor -poti -ignition plug -ignition module -fuel pump -injection nozzles all four -kat -cylinder head + one-out valves -motor oil compression in warm condition : cylinder 1: 10bar- 2: 10bar- 3:9.5bar- 4: 11bar pressure test passed n. co2 test passed. cable and ports all checked. when the engine is cold it runs clean, which goes about two minutes after it starts to bubbling and runs a bit restless.minimal speed fluctuations. after that the ignition plugs are totally black and rusty. spit consumption is also too high. guess so around the eight to nine liters. where is the error? I’m still getting knocked with the cart. have forgotten something. when reading out comes the error code p0300 I hope you can help me. in vo rraus thank you already
