hello I am new to here. and to audi I had bmw in the past, any way here is the story. I bought this 03 a4 1.8 turbo 128,000 m and it was running great no issues. the first few hours. so I decide to get on it and see how it runs and I though I blew a head gasket, it rev up to 6000 went through the gears and then slowly drove to my parking spot. as i was driving 20 mph mins from high rev through the gears it just started burning oil like i was a drag car doing a burn out. and miss firing. so i turned it off right away. pulled the plugs number 1 covered in oil. did a leak down test 2% leak each piston. no contamination in oil or antifreeze. so i look at the oil stick. and its 3 quarts to high. ! i drain it to normal level, take a look into the inter cooler, yup lots of oil. then the throttle body lots of oil. but it is now running so so so rich its just over loading it with fuel burns your eyes in seconds of starting. and its very hard to start. so we plugged the computer in and we noticed bank 1 o2 is reading 20 degrees C and not changing a degree. then bank 2 320 degrees C and moves up and down a few degrees. so i replaced it and still same no change at all. that's all i changed i will be running another test tomorrow, has anyone ever seen heard this happening? im at a loss. idont get it. email me asap with any suggestions thank you
oh and when i drive it and get it reving up to 4500 it and the turbo is at 13+ its cleans right up and runs great. like it is getting the air it needs to burn all the excess fuel.
