New injectors being fitted to a VAG 1.6 diesel (as fitted throughout the range). This is a common issue which causes excessive engine noise, poor running and poor drivability. First there is a software update needed before running a procedure to adapt and test the injectors. In many cases this will improve the engine noise and drivability issue.

Bad news. Many cars will be improved through running the minimum quantity adaptation. In some cases the injectors are too worn and out of range, in which case they fail to complete the procedure. Unfortunately, this car needs all 4 injectors replacing.
