Code DGLAB_i007 was reported by the “Diagnostic log entries” controller in the car. The letter “i” in the middle places it among entries of the information type.
Internal diagnostic and informational events the car records for service. These are not faults — more like notes that some condition returned to normal.
A purely informational record of a state change. Usually it means something returned to normal.
This is how the fault is named inside the car's firmware. For codes without a description it is the most precise clue there is — the name itself says what the event is about.
The text below comes from Tesla's technical documentation. We leave it in the original English so that translation cannot shift its meaning.
All messages the local ECU expects to receive from the DI ECU are being received or the DI non-drive mode is CAN inactive.
Drive functionality may be missing.
One or more of the expected CAN messages from VCLEFT were not received.
A message the local ECU expects to receive from the VCLEFT ECU hasn't been received within the expected timeout or the drop rate is too high while the VCLEFT is CAN active. The ECU is considered CAN active when VCFRONT_vehGoToSleep is 0.
All messages the local ECU expects to receive from the VCLEFT ECU are being received or the VCLEFT ECU is CAN inactive.
Vehicle functionality may be missing.
If a task failed to initialize.
One or more of the expected CAN messages from PARK were not received.
Copy it exactly, letter and number included. Photographing the screen is safest — codes often differ by a single digit, and mixing them up leads somewhere else entirely.
Some codes clear after a screen restart or after the car sits locked for a few hours. If the code does not come back, it was usually a one-off glitch.
A one-off entry and a code that appears after every drive are two different things. It helps a service centre enormously if you know exactly when it shows up.
With airbags, brakes, steering and high voltage there is no point waiting it out. With the other groups you can watch and see whether the code returns at all.
Error codes are only part of the picture. For cars on TesList you also see battery health pulled straight from the vehicle, plus a price calculator that works out from current listings what a given car is actually worth today.
