What U060B means
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.
U060B at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U060B
- Check engine light
- Noticeably less power, boost held low
- Fault may come and go with engine vibration
Common causes of U060B
- Most likelyWires broken by vibration right behind the sensor connector
- PossibleBoost sensor electronics failed
- PossibleLoose terminal or oil in the connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U060B means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0B | The exact fault in that area. |
What to do next
- Note U060B and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U060B
What does U060B mean?
U060B means "Lost Communication With Turbocharger/Supercharger Boost Sensor A". Boost sensor A measures charge air pressure after the compressor and is often a SENT pressure sensor with built-in temperature measurement. It is a generic code, so it means the same on every make.
Is it safe to drive with U060B?
Drive gently and only to a workshop. With U060B the car can go into limp mode (reduced power) to protect itself.
Will U060B fail an emissions test?
Yes, it can. U060B is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is U060B to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will U060B clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
