Some post have a concern about the health of the ICE 1,4 L engine if infrequently or never used.
Looking at the A3 "eSelf Study Program 970253" Book / Manual, I was happy to read about this unique to the e-Tron ICE engine. See below what Audi modified to assure long life...
Internal combustion engine
The A3 Sportback e-tron uses the EA211 series 1.4l
engine. Because the transmission is 2.26 in (57.5 mm)
longer to accommodate the e-machine, the engine is
mounted further to the right than in the standard A3
Sportback.
The main bearings, the connecting rod big end bearings
and the piston rings of this engine have special coatings. In
addition, piston backlash has been adapted and the cylin-
der liners are plasma-coated.
The Audi A3 Sportback e-tron can be driven in electric-only
mode. This can result in periods of time during which the
internal combustion engine is not in use.
The internal combustion engine is started by the e-machine.
Unlike the Q5 hybrid quattro, there is no 12V starter motor.
Engine Control Module J623 sends a start message to DSG
Transmission Mechatronic Module J743. Clutch K0 is closed
and connects the e-machine rotor to the internal combus-
tion engine’s crankshaft. The rotor brings the engine’s
crankshaft up to starting speed. J623 then enables the
ignition and fuel injection and the engine starts.
If it is necessary for the internal combustion engine to start
when the vehicle is running in electric-only mode, the torque
from the e-machine is increased by the amount necessary to
start the internal combustion engine when the clutch closes.
This prevents judder. After starting, clutch K0 is opened and
the internal combustion engine runs at no load. After the
speed of the internal combustion engine has been adapted
to that of the e-machine, clutch K0 is closed again.

During electric-only driving, the internal combustion
engine can start in order to heat up the catalytic converter.
To ensure wear-free starting of the internal combustion
engine after electric-only operation, clutch K0 closes and
the e-machine turns the engine over until sufficient oil
pressure is obtained.
In the U.S. market, the engine is also equipped with sec-
ondary air injection
