When documenting a missing hot air tube and a plugged EGR hose, which TAC and EGR statuses are correct?

Explanation:
The key idea is how TAC and EGR statuses are recorded based on what you observe. The hot air tube is part of the TAC assembly, so when that tube is missing, the TAC status should be marked as missing. For the EGR, the status category reflects whether the EGR hardware has been modified from stock. A hose being plugged blocks flow but doesn’t change the actual EGR hardware configuration, so the EGR is recorded as normal. In other words, missing TAC matches the missing tube, while the EGR remains in its original configuration despite the plug, hence normal.
