2000 audi a4 1.8t atw
The car has ran great other than a very slight misfire that I've been trying to find. (Changed coils, plugs, and did a compression test) car ran fine for several days after all changes. Then the code appeared.
I have a code listed for problem. No fire to plugs tried coils and plugs cuz I had spares no help. I have fuel. Tried a spare ecu. i have changed both relays in the ecu box just to be sure I had the right one and my car still has no fire.
I am right in my research saying the j271 is in the ecu box? All wireing and connections are crystal the ecu box is 100 percent dry. The fan is not running with the car off
