Hy

I have 97 year audi a3 with 1.8t AGU engine. I had a fire in the car which started from battery and now im building it back up. All ecu wire lines, vacuum lines and engine sensors were melted. So i did new wires to ecu, bought some new sensors and got the car running again. But problem is that i dont have all the sensors what engine needs and its taking to much fuel. Right now i have IAT sensor, coolant temperature sensor, engine temperature sensor, N75 valve, MAF, hall sensor, O2 sensor and detonation sensor. I cant get connection with my ecu because i dont know how to connect (is there a single wire that goes to pin?) and on what pin number DLC is? Right now i´m not sure what sensor i would need more? I know that EVAP and N249 i can connect with resistor 10w and 330ohm, i have found EVAP connection in ecu pin but i cant find where is connection for N249 in ecu. Does someone know what sensors do i need more to get it running nicely again.

i´v found out that im missing altitude sensor and there´s no map sensor also which one i need? Is there some audi 1.8t cars without SAI system, because i can´t find it in factory wiring diagram that system?

I'm thankful for any kind of help
