Hi guys, can anyone possibily shed some light into something for me.

Looking through some documents, i have a job sheet for when my car was booked in and the technician in the dealershi wrote something after the Odometer reading, from what i can see is looks like WO or WD - do you know what this could mean?

Also, when the technician states "Carried out a drag for code", what does that mean?

Many thanks in advance.
