If your OBD-II scanner displays a P0306 code on your 2022 Audi Q5, this code requires diagnostic investigation because the standard Q5's engine doesn't have a cylinder 6.
2022 Audi Q5 Engine Options
The 2022 Audi Q5 lineup includes:
- Q5 (standard): 2.0L turbocharged 4-cylinder (261 hp) - P0306 is invalid
- Q5 PHEV: 2.0L turbo-4 + electric motor - P0306 is invalid
- SQ5: 3.0L turbocharged V6 (349 hp) - P0306 is valid
If you have the standard Q5 or Q5 PHEV with the 4-cylinder engine, P0306 is physically impossible since those engines only have cylinders 1-4. If you have the SQ5 with the V6, this is a legitimate code requiring diagnosis.
Verify Your Model
Check your rear badging - "Q5" indicates the 4-cylinder, while "SQ5" indicates the V6. The distinction is critical for determining whether P0306 is valid.
