2001, ML 270 CDI. Recently purchased. Trying to sort out many problems. Car runs, but blow black smoke and no power uphill. MAF is not getting 12 volt supply from Red/blue wire post 4 in connector. when test 2 and 3 show 5 volts, but 3 & 4 show none. traced this wire all the way to ECU. Solid wire ... Tried to run hot wire from battery, but getting alarming constant beeps possible from throttle module...So maybe MAF is dead but first need to power it to test..Any help is appreciated...
I have cleaned inlet manifold and all seems OK But need to know how much lateral movement should the actuator of motor produce.. Mine only open flaps fractionally some 20%.
Next project is vacuum system and turbo( dripping oil)
Many thanks.
