EML engine problem

[frenchgooner]

My Vito 115 (w639) went into limp mode, and then EML came on. Ran diagnostic, codes p2514 inline vent heater and another code for the pressure sensor boost came up. Cleaned up the sensors checked connections etc.. cleared fault. all ok for a week, then same problem again. same codes on diagnostic, so changed pressure boost sensor and inline vent sensor, cleared fault and same problem back within 8 hours. Running the diagnostic again in the morning, but any suggestions on what next?

Many thanks

Seriously no one's got anything?

what diagnostic tool you using ??? If not STAR then you need to get the codes read and fault history log from it to help pinpoint your issue .

Check the actuator rod on the turbo, they can stick and trigger boost codes.

yes, agree with sparkydude. i had the same problem before. then i changed pressure boost sensor and inline vent sensor, checked connections and the actuator rod on the turbo, cleared fault by SDconnect C4 bundle. the problems never came
