I have a 99 TDI swapped Ford Ranger. I have Audi A4 dual intercooler setup. The map sensor bung is of course in the Audi intercooler. Since the sensor for the Audi is a different bung size than the Beetle, I’m wondering what comparability there is between the 2.5 bar map sensors from different VW/Audi models.

Currently I’m running a used 2.5 bar map sensor I got from a friend (Audi A4 1.8T sensor) and my IAT reading is currently 271 degrees, which I’m sure is the top of the sensor range. I’m not sure if the sensor is faulty from rattling around in his parts bin or if the sensor isn’t compatible with my TDI ecu.
