U060C code meaning
Lost Communication With Turbocharger/Supercharger Boost Sensor B
Network system Generic code U06xx codes Check engine light
What U060C means
Boost sensor B is needed where charge pressure is measured twice: on twin-turbo V engines with one charge path per bank, on two-stage systems between the stages, or after the charge air cooler in addition to sensor A. When it is a digital SENT device, its frames carry pressure, often a temperature value, a status nibble and a CRC. U060C sets when those frames from sensor B are missing, corrupt or flagged as invalid by the sensor itself. No manufacturer documents this code publicly; the logic follows Audi's bulletin for U060B and the CARB 1968.2 rule that lost communication on a digital input needs its own code. P0239 to P0242 are the analog counterparts, and P023E compares sensor B with manifold pressure. The controller usually limits boost on that branch.
U060C 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 U060C
- Check engine light
- Reduced power with boost limited
Common causes of U060C
- Most likelyDamaged wiring to boost sensor B, often near hot turbo plumbing
- PossibleBoost sensor B electronics failed
- Less likelyLoose or oil-soaked connector at sensor B
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U060C means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0C | The exact fault in that area. |
What to do next
- Note U060C 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 U060C
What does U060C mean?
U060C means "Lost Communication With Turbocharger/Supercharger Boost Sensor B". Boost sensor B is needed where charge pressure is measured twice: on twin-turbo V engines with one charge path per bank, on two-stage systems between the stages, or after the charge air cooler in addition to sensor A. It is a generic code, so it means the same on every make.
Is it safe to drive with U060C?
Drive gently and only to a workshop. With U060C the car can go into limp mode (reduced power) to protect itself.
Will U060C fail an emissions test?
Yes, it can. U060C 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 U060C 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 U060C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
