ML270 losing power intermittently

[John Hall]

Evening everyone has anyone had a problem with their ML270(53) intermittently losing power ie kick down not working, no boost, no management light coming on, probably happening 50% of time !!
Changed MAF & MAP sensors thought I’d put it out there before going down the inlet manifold route
Thanks in advance

Before you throw more money at it, it may be worth getting codes read, or driving with something like icarsoft connected to read actual values as it happens?

check battery fully charged, MBs seem to hate low batt voltage, and do strange things.

^^^^ as Flyinspanner rightly says, really no point in guessing, could be one of about 350 things "ask the car, the car knows"

As above. Good chance could be egr coked up and sticking, if it is intermittent. Most else would be "all the time"
