Hi, I'm troubleshooting a problem with my Passat. Very rough cold start idle and intermittant rough idle with smoke when warm. Hooked up VagCom for cold start and put it on MB13. Initially the car was very rough and injector 1 read 0.0, 2 and 3 were 2.99 and number 4 had no value for some reason. After a couple minutes #1 toggled between .02 and 1.04. The concensus is my car has a bad injector or injectors, how do I interpret these numbers? Thanks.
