U060BLost Communication With Turbocharger/Supercharger Boost Sensor A
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Boost sensor A measures charge air pressure after the compressor and is often a SENT pressure sensor with built-in temperature measurement. U060B means the engine controller no longer hears from it. Audi documents the code for the 2022 to 2025 Q5 and SQ5 family (bulletin 2074392): the MIL comes on and the engine control unit stores U060B00 against G31, the boost pressure sender, either intermittent or static. Engine vibration can break the three wires right at the sender connector, which may only show once the terminals are unpinned or the tape is removed; the fix is a new pigtail with set lengths, and production changed from January 2025. P0235 to P0238 cover an analog sensor's circuit faults. Boost control falls back to a safe low level.
- What you may notice
- Check engine light
- Noticeably less power, boost held low
- Fault may come and go with engine vibration
- Likely causes
- LikelyWires broken by vibration right behind the sensor connector
- PossibleBoost sensor electronics failed
- PossibleLoose terminal or oil in the connector
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €40 – €350
