any help on this appreciated guys.

P1189 inlet port shut off open circuit

P1403 exhaust gas recirculation (EGR) open circuit

P1470 charge pressure negative control open circuit

P1636 electric suction fan open circuit

P0100 Bank 2/5 (hot film mass airflow sensor) signal voltage is too low

HELP :wallbash:
 
A broken feed wire in the loom is my first guess.
 
Could be just an earthing problem or a disconnected wire. You need a map of the electronics in the area.
 
Have not had this problem specific to an ML. But many times on a 210 ! The air mass sensor wiring gets all mushy and blows the fuse.
Maybe have another look? A proper look???
