I have an allroad c5 with the bau engine. 2.5 tdi. The ecu light came on and I plugged in my obd reader I always keep in the car. It gave error code
"P0098 intake air temperature sensor 2 circuit high bank 1"
It reappears each time I start the car. I plugged in my vcds and it gave a slightly different code but what seems to be the same fault.
"17569 manifold temp sensor (g72) p1161 - 35 - 00 - open or short to plus"
I have measured the output in measuring blocks and it is giving what seems to be a reasonable output. The ambient temperature is about 3 degrees whilst the intake temperature is about 29 degrees with the car warmed up. I had an old maf from another car so plugged this in and had no joy. The same code reappears. I can't guarantee this item so I want to check out the wiring. Typically my elsawin is playing up so I can not see the current flow diagrams. Can anyone supply them. Also is there anything else I am missing. I assume there is only one intake air temperature sensor. This is the one built into the maf sensor. Anyone got any suggestions as to what to try next.

Cheers
