w168 1998 petrol
w168 air intake temperature below zero ?!

Hello, I need some help. I have a VCI DS150E OBD scanner. I noticed that the air intake temperature is being reported below zero. We have 22C here today so it's pretty strange to read that data.
I am talking about a first version (1998) petrol w168 with MAF/Temp Sensor soldered to the MSM ecu.
Could anyone with an OBD equipment and the same car check that data and see what it returns?
I had this ecu repaired for MAF at Ecu testing and even before sending the unit the temp was reported below zero, I asked to check the temp sensor too, I don't know if they did it but the temp is always being reported like that. My understanding is the engine will use more fuel if the ECU thinks the weather is cold.

Thanks

Solved. The IAT was faulty, repaired at Ecu Testing (uk).
