Hi, appreciate your speedy reply. Its a 2004 VW Passat V6 4 motion, the engine is an Audi A6 which is built in many cars! Injectors, coil checked and plugs are new. it is cylinder 2 that makes problems!

Unfortunately I don't have the service manual for that vehicle, but the P1226 code indicates that there is a wire problem for the injector #2. Since you know that the injector is OK, then the next step is to check the wires from the injector to the Engine Control Module (ECM)
