I have an Audi A4 TDI , engine code AJM , 2000 model.
Been having a bit of trouble with an intermittent missfire , usually under load when accelerating.
Retrieved fault code front management system.
469A : Valve for unit injector cyl.1 circuit defective.
Tried adjusting the injector valve on no.1 cyl but made no difference.
Has anyone had this code before ? , are injectors a common problem with these engines?
Any feed back much apreciated.
