    P226300 when cruising above 130kmph

    Hey there i'm struggling with this issue on my 2009 C250 CDI. CEL comes on and the car goes into limp mode. Hooked it up to a Star tester and i'm getting P226300 - boost pressure deviates from the specific vacuum. This only happens when driving above 130 kmph, at a constant speed. The rest of...

    Loud Engine Fan (W204)

    Are you by any chance referring to this sensor on the evaporator? I understand it's located in the center console, behind the small round hole. I guess I'll go get a star diagnostic... or is it possible to get the temperature reading on universal testers as well?

    Loud Engine Fan (W204)

    Hello! I`m having a similar problem on my C250 CDI. The fan kicks in after i start the car and it's very noisy. It happens even with the A/C turned off. This just started happening today. The A/C also stopped working, when i turn it on it blows hot air even when i set it to minimum. Weird thing...

    C250 CDI - radiator fan not kicking in

    The coolant temperature in my C250 sometime hits 105C and the radiator fan still doesn't kick in. In normal driving conditions the temperature stays at about 90 - 95C. The ambient temp is about 25C. But when I`m in the mood to floor it and shift at 4k rpm for a couple of minutes and then pull...

    C250 CDI - No boost at cold start

    Sooo, i went to another Star Tester. But the car was already acting normally when i got there. So he didn't find out much. He only said my turbo isn't acting normally and that i should get it checked. He suggested i start by checking if any of the actuators are stuck. I couldn't check the...

    C250 CDI - No boost at cold start

    The car feels very sluggish in the morning. I don't think the turbo is kicking in at all. It revs very slowly as well. It does it for less than a minute, then the power kicks in all of the sudden. Only happens in the morning. The car runs without any problems the rest of the day. I went to a...

    W204 C250 CDI fault code P0472 only with cold engine

    When they did the DPF delete they removed the differential pressure sensor. They said it was enough for this type of car. Anyway, i was getting P0471 before i did the DPF delete so i don't think it's related. I cleaned the sensor but the problem didn't go away. It only triggers the fault code...

    W204 C250 CDI fault code P0472 only with cold engine

    Sooo... i cleaned the Exhaust Back Pressure sensor. But the problem didn't go away. I think i`m gonna order a new sensor and see if that helps. Before i do that, i will also clean the EGR. I saw that the sensor is mounted directly on the EGR... Could a clogged EGR cause Exhaust Back Pressure...

    W204 C250 CDI fault code P0472 only with cold engine

    I`m beginning to think that the problem is the sensor itself. Does anyone know where the back pressure is positioned in a w204 OM651.911 engine? I wanna take it out and try cleaning it... :confused::confused::confused:

    Hi there! I had some problems with my 2009 C250 CDI. The DPF was clogged so i went to a tuning company and had it removed. The problem is i`m still getting P0471: Exhaust Pressure Sensor Range/Performance. I used to get it before i removed the DPF as well. I get the fault code only in...

I got stuck alot :/ About a month ago it went away. I don't know if it was because i drove past a huge...
