I have a strange problem with 1.4 16v gti 1998 AFH engine. On group 001 field 2 there should be coolant temperature and on group 002 field 4 air temperature. But here they change the places. Also on group 001 field 4 should be all zeroes when coolant is under 80 degrees and if temperature is over 80 degrees last zero should be 1, but also work in reverse order. What can be the problem and how to solve?
