GM's Labor Time Guide has the 'variable-add diagnostic time' which says, 'You may claim up to the allowable labor hours depending on actual time performing diagnosis. (You may claim 0.0-0.3).'  Say the tech has .45 for his actual time and the labor op pays .30, but it has the add-diagnostic time (as stated above). What would be the final time paid to the technician? How much are we entitled to under P&P? Thank you in advance for thoughts on this."

Warranty Administrator responds: "If you time-record all the repairs, then the policy goes with the actual time; in this case .5 hours (.45 rounded up). The right submission would be 0.3 for the base operation and 0.2 for variable diagnostic time. This is actually one of the shortfalls of time-recording every repair. Had no time records been present you could have relied on management's decision of the appropriate time, up to the maximum of 0.6 hours.

When the technician has a single time punch covering the entire repair (the replacement and diagnosis), then you can't show efficiency in the base time. In other words, all that is allowed is the remainder from subtracting the base time for total time elapsed. If the tech separated the punches, for instance 9:00am - 9:21am = Diag    9:21 - 9:27 = Replace, we still have the same .45 hours, but the tech could claim 0.3 diagnosis and the 0.3 for the R&R.
