Quick answer

For certain U.S. Audi models, U112300 is documented as “Data bus error value received.” Audi communications show it can occur as either an intermittent or static DTC in specific contexts. A static entry may not erase; an intermittent entry may return when its conditions recur. The code alone does not establish driving or charging safety.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does U112300 mean?

For certain U.S. Audi models, U112300 is documented as “Data bus error value received.” Audi communications show it can occur as either an intermittent or static DTC in specific contexts. A static entry may not erase; an intermittent entry may return when its conditions recur. The code alone does not establish driving or charging safety.

2. Technical explanation

Verified Audi manufacturer communications describe U112300 in more than one diagnostic context. In communications concerning control-module diagnostic entries, U112300 may be stored with symptom code 169984 or 169948 as intermittent, and with symptom code 303360 as static. Those communications state that the listed DTCs are logged for design reasons. Separately, Audi communications concerning capacitive steering wheels state that two U112300 DTCs with symptom code 2153 point to a malfunction of the capacitive steering system. The capacitive steering wheel uses touch sensors to detect whether the driver’s hands are on the wheel for driver-assistance attention monitoring. The exact interpretation depends on the vehicle, control module, symptom code, and accompanying DTCs.

3. What system is affected?

Data bus communication is identified in the DTC description. In a separate Audi TSB context, U112300 with symptom code 2153 is associated with the capacitive steering wheel/driver-attention sensing system. A single affected system cannot be established from U112300 alone.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • A static DTC may not erase.
  • An intermittent DTC may erase but can be logged again when the conditions for it occur.
  • For the capacitive-steering TSB context, a malfunction of capacitive steering is identified; specific driver-observable symptoms are not established by the supplied evidence.

6. Possible causes

  • In specified Audi communications, certain U112300 entries are logged for design reasons.
  • For U112300 with symptom code 2153 in the capacitive-steering TSB context, Audi identifies a malfunction of the capacitive steering system.
  • Audi instructs inspection for exterior or mechanical steering-wheel damage, such as deep scratches, in that capacitive-steering context. No broader cause can be established from the supplied evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Record the complete scan result, including the control module, symptom code, and any accompanying DTCs.
  • Do not assume that clearing an intermittent U112300 resolves the underlying condition; verified Audi information states it may return when its conditions recur.
  • Arrange diagnosis by an Audi-qualified service provider when U112300 is accompanied by steering-wheel or driver-assistance concerns.
  • Do not perform airbag, steering-wheel, or high-voltage system work yourself.

10. Step-by-step troubleshooting

  1. Confirm whether U112300 is static or intermittent and record its symptom code.
  2. Check for accompanying DTCs. In one Audi communication context, U112200 and U012700 may also be present; this does not establish that they are present on every vehicle.
  3. For the capacitive-steering context identified by symptom code 2153, Audi directs service personnel to inspect the steering wheel for exterior or mechanical damage, such as deep scratches.
  4. Further diagnostic and repair steps are not established by the supplied verified evidence.

11. When to contact service

Contact an Audi dealer or qualified Audi service provider, particularly if the code has symptom code 2153 or is associated with steering-wheel/driver-assistance concerns. Provide the full scan report and vehicle identification details.

12. What the service center may check

  • Identify the module that stored U112300, its symptom code, and whether the entry is static or intermittent.
  • Review accompanying DTCs.
  • For the symptom-code-2153 capacitive-steering context, inspect the steering wheel for exterior or mechanical damage as directed in Audi manufacturer communications.
  • Audi service documentation may require airbag removal in the capacitive-steering procedure; this is professional service work and should not be performed by the vehicle owner.

13. Possible repair or resolution

  • For design-related DTC entries described in the cited Audi communications, the static DTC may remain stored and an intermittent DTC may recur when conditions return.
  • For the capacitive-steering context, the supplied evidence establishes that Audi has a service procedure, but it does not provide enough verified detail here to state a specific repair outcome.

19. Frequently asked questions

What does Audi U112300 mean?

The verified description is “Data bus error value received.” Its diagnostic significance varies by context, symptom code, and control module.

Why will U112300 not erase?

Audi communications state that static DTCs in the cited diagnostic context cannot be erased. This does not establish that every U112300 entry on every Audi is non-erasable.

Can an intermittent U112300 return after clearing?

Yes. The cited Audi communications state that intermittent DTCs can be erased but will be logged again when the conditions for them occur.

Does U112300 always indicate a failed part?

No. In one verified Audi communication context, the relevant DTCs are logged for design reasons. In another context, U112300 with symptom code 2153 points to a capacitive-steering malfunction.

Is U112300 related to the steering wheel?

It can be. Audi communications identify U112300 with symptom code 2153 as pointing to a capacitive-steering malfunction. U112300 alone does not establish a steering-wheel issue.

Is it safe to drive or charge with U112300?

Not yet established by verified evidence.
