Audi AAN: MAT sensor pullup
« on: July 07, 2015, 12:43:07 pm »
Hi, I took my v3 out of case, to install camHALL inverter. Thought I could mind as well install 2k7 pullup for NTC type MAT sensor, which is required by the vems homepage. Does anyone know, where its located on v3.8 schematics or how its signed? Thanks for any help!

You don't need to install any other pullup, your VEMS will work perfectly with NTC sensor just like it is at them moment.

Okay, one strange thing I noticed while crancking long enough and many times in a row, IAT started to climb up suddenly for no reason.  From 20°C up to 45°C and then slowly fell back. Uploaded 2252-256 patch, but nothing changed. Any guesses?

This problem doesn't seem to occur anymore, after the car has started. IAT stays around 20-25°C
