Was not the factory MAF. Boy am I learning about Land Rover. The company I ordered from has a Bosch sensor that I can swap, or do I eat the original, and if so where can I get the "right" unit? The plug wires should be here this afternoon, but the dealer will be closed before I get them installed...if I have time today to get by before they close.

 

Check your air cleaner cover, make sure that it seals properly and nothing is broken. Also check on the air intake hose after the MAF, there is a hose that attaches to it - make sure that connection is good and not torn. I was getting a bunch of the same error codes and after replacing my broken air cleaner cover and air intake hose the errors went away. I'm not saying this is your problem, but check those items just in case. The wrong MAF sensor will also throw errors.
AB stocks the right stuff http://www.roverparts.com/Parts/MHK100800OEM.cfm
They may not be the cheapest around, you can try others like DAP as well http://www.dap-inc.com/
You can use the same Bosch part number as the original one on the vehicle.

 

Thanks to all, but I'm not sure who will get credit for the "fix." Picked up dealer MAF on way home, and had Magnacore 8mm waiting from Apex. Installed both and put RTV around repaired IAC valve hose connection to air intake hose. Went for pizza with family while RTV set. Cleared Codes. Drove about 15 miles and no Service Engine Light! Seems to lack some power, but my daughter drives it, she will have to let me know whether that is normal or not.
