mikeb3 Posted April 4 Share Posted April 4 (edited) 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 Edited April 4 by mikeb3 Quote Link to comment Share on other sites More sharing options...
David021 Posted April 14 Share Posted April 14 Yes. You have to change or refurbish the injectors. Had the same problem. I recommend that you change or refurbish all of the injectors, so you won't have any problems afterwards. Quote Link to comment Share on other sites More sharing options...
axaduj Posted 12 hours ago Share Posted 12 hours ago Hello, and thank you for the informative video. I'm hoping you can give me some insight into a problem I am having with my 2015 ford flex limited. For the last couple of months my flex has developed a stutter between 25 to 45 miles mph. I can see the tach jumping during this stutter.
