Morning All,
Two weeks ago our A6 Allroad died on the drive after moving it 20yds.
Cranked and cranked, but wont fire.

Its taken a while for the village garage to look at it.

He cleared the codes and it started an ran for 5 secs. died.
Cleared the codes, and it ran for 10-15 mins on the forecourt. Was brave enough to take for a drive too, and seems to be working ok.

The error codes were as follows. We are thinking it is the Ad Blue system? Or ultimately, worried that a sporadic issue may resurface (error codes come from a reason after all) The Ad Blue injector has signs of crystallisation around it, so a leak somewhere.

The OH uses the car for pulling horsebox etc and the thought of it being used with another breakdown round the corner is not good.






Anyone good at reading between the lines on the possible causes?

Closing this out should it help....

The Ad Blue pipe to the injector had failed at the fitting / connector - seems the AdB had not been spraying for some time in to the injector and we saw crystallisation of the stuff indicating a leak.

New Pipe, and gave it a hoof this morning and seems to be on top of the issue.
