A6 Bre injector fault

[jeff111]

Hi need help with an A6 2.0 tdi injector fault .when running car was only running on 3 cyl out of 4 .

scanned found injector 4 was at fault over fueling .

now removed injector ready for testing .

If a replacement is needed does it need programming to car

just for info . car had the low oil pressure light on

Replaced turbo and feed pipe , still had light on .

replaced the balancer shaft and key way.

Any help would be appeciated

Hi, this is only an educated guess but how long had this problem been on going?, it possible the extra fuel has got in with the engine oil, check the level, this would have the effect of thinning the oil making it harder for the pump to work, sort the injector and it will need re coding then sort out the low pressure light.

Hi only  injector fault now  . low oil pressure was due to the balancer shaft keyway issue
