The other day when my wife was driving her 2010 Range Rover Sport 5.0 with 40k miles the check engine light went on. When she got home I checked the codes and received
0x100 P0100-00 Mass or Volume Air Flow Sensor A Circuit
0x101 P0101-00 Mass or Volume Air Flow A Circuit Range /Performance
0x2101 P2101-00 Throttle Actuator A Control Motor Circuit Range /Performance

With a little research I got to possible the MAFs, so i took the 2 MAFS out and cleaned them. I then seen some things about cleaning the throttle body, this is where it all goes wrong.
When i get to the throttle body I unplugged the wire connector, then unhooked the 90 degree tube that sends coolant through the throttle housing. I do not know what i was thinking but when doing that the remaining coolant flowed out and got into the throttle body wire harness, not sure if it got into the connector going to the throttle body. Once I put everything back together I was getting the "Restricted Performance" light on the dash along with the red !. I drove the car around the block and the "Restricted Performance" and ! lights went off. I still have the check engine light on. Also now the motor and wire connection to the Throttle Body is making a load humming like noise, very noticable when ingnition is turned on but not engine running. I then checked for codes again and this is what I have now

0xC102 U0102-00 Lost communication with transfer case control module.
0xC300 U0300-00 Internal Control Module Software Incompatibility

I also hear a swoosh type sound like air when car is in park and i hit the gas peddle, seems to be around the area of the throttle body.


I do not even know where or what to do and hate to take any of my cars to the stealers please if anyone can help me out, it is my wifes daily driver as well.

Two things spring to mind. You only need to post a topic once. Please feel free to read the forum guidelines again.

A weak battery will throw all sort of erroneous codes. All Rover take a pristine perfect charging system at all times. If your battery is old, weak or has a single dirty connection any where in the circuit your battery will not be accepting your alternator's attempt to charge. Likewise a weak alternator can cause voltage issues. Clear all the codes, make sure your battery is charged over night and reread your codes. Chances are many of those codes will disappear because most of them contradict each other. Your sensor can not provide both low and high signals in the same reading unless these are historic codes conflicting.
