BMW E87 diesel lacks power
Why does my E87 N47 diesel run unevenly at idle and lack power?
The cause can be faulty exhaust pressure sensors and a clogged passage in the particulate filter. New pressure sensors and a forced regeneration (a cleaning burn of the filter) restored the power.
Is the boost pressure on an E87 M47 diesel normal when the target is 2600 mbar and the actual is 3000-3100 mbar?
The readings in the diagnostic software are absolute pressure, that is, atmospheric pressure and boost pressure combined. Sea-level atmospheric pressure is about 1000 mbar, so the boost pressure is obtained by subtracting it from the reading. The car works normally and does not go into limp mode.
