I have a 2010 jetta tdi with 40980 miles. The mil indicator is on and I scanned with code reader and it shows po272 which says "Cylinder 4 contribution balance fault" , the dealer did charge 115.00 to tell me that this code was what they got as well. I have a hard time believing that this is all they know. They said they could install new injectors but can't say for sure if this is the problem. It's so expensive that i'd like to see if anyone might have had this same issue. I may take to a second dealer to see what they say but, of course, they charge 105.00 to hook their VAS to the car. I am looking into getting a VCDS. This is a great site , I have learned a lot. - Thanks for any help.
