Hi!

I have an mcs r56 2009. When I ran carly diagnostic I lately read the two codes

00289D DME: Boost-pressure sensor, electric

002C96 DME: Power management, closed-circuit current violation

The first is the map sensor which I will remove and clean. The sensor has the 0261230135 number on it.
does anyone know what's the difference with the 0261230134?

I dont know what the second code might be. Any thoughts?

 

I think I sorted it out. The map sensor (boost sensor) was a little dirty. I removed it and cleaned it. What caught my attention is that it was a little oily. I checked the pipes but I didnt find any oil. I removed the tmap sensor located on the left pipe before the noise maker and it was dry and clean.
The other fault I think was because I leave the obd reader plugged. I removed it and I will report back after a week.

The sensors are map (135) and tmap(134).

 

The second fault is gone, with the removal of the obd reader, the Boost-pressure sensor, electric remains. Any thoughts? Should i order a new sensor? and which one? the MAP or the TMAP?

 

With the sensor replacement the other code cleared too

 

Which sensor did you replace?

 

eventually both, the temperature/pressure sensor (13627535069) and the inlet pressure sensor (13627540508)
