2000 a4 quattro 1.8t had misfire codes 300 301 302 and sometimes 303&304 drivin me nuts, would spit and cough when cold and be in limp mode warm. changed coil packs, no different. also had a previous 1128 codecouldnt find any vaccum leaks. AHHH!! when I unplugged maf after reading a post, car ran almost perfect except for a slight miss at idle. after changing maf all is perfect.
Also, oil light is flashing occasionally. put an analog guage on it and after normal operating temp is reached, oil pressure is 12psi at idle and 60psi at about 2500rpm`sthat sound about right? I am suspecting the oil pressure sensor. hope this helps someone.

 

You may want to check a bently/haynes to make sure, but it sounds about right.

 

thanks, hopefully its in specs, Id rather change a sensor than an oil pump

 

Was you oil full?
What oil do you use?
