Hello! I own a 2001 W210 E200 kompressor with LPG system (curently disabled) (163 hp version) and I sometimes when I start it, the kompressor gives no boost. The car is in service for 2 weeks and I m desperate. After several scans, the mechanic got 2 errors. P201E and P0420. When the car has no boost the speedtronic error also appears. I bought the car without a catalytic converter and after 5k km driven without it (on gasoline and LPG), after this problem appeared, I disabled the LPG system and I installed a new one but it didn t solved the problem. At this point I told my mechanic to clean the MAF sensor but I don t think it will solve the problem. I guess it could be a faulty O2 sensor? I know that at this model, the bypass valve is controlled by the ECU.
