Hi, I'm new here and could really do with some help. I have an Audi A4 B8 2.0 tdi 2009. The car started to blow out quite a bit white smoke from the exhaust about 3 days ago, it still seemed to run ok but the smoke has now seemed to have got a bit thicker and also a bit of engine shake on start up and sometimes a bit of a clicking noise when revving and also a bit of a misfire. There are no warning lights on the dash. I had the breakdown company out yesterday and he seemed to think it was a faulty injector. I also had a mechanic do a scan this morning and it came up with these results....
Cyl 1 Injection quality variation value (mg/stroke) -2.52
Cyl 2 Injection quality variation value (mg/stroke) 0.39
Cly 3 Injection quality variation value (mg/stroke) 1.09
Cyl 4 Injection quality variation value (mg/stroke) 1.01
So am i right in thinking that Cyl 1 injector is faulty as the mechanic didn't seem to know a lot about diesel injectors
Any help would be appreciated
