01176 - Key
01176 - Key: Signal too Low
Possible Symptoms
- Malfunction Indicator Light (MIL) ON
Possible Causes
- Immobilizer
- Wiring and/or Connector(s) from/to Immobilizer Reader Coil faulty
- Immobilizer Reader Coil faulty
- Immobilizer Transponder in Key faulty OR incorrect Transponder in Key
- Remote Control
- Remote Control Battery low
- Remote Control faulty OR incorrect Remote Control used
Possible Solutions
- Immobilizer

Special Notes
- This Fault Code can be stored in due to Remote Control or Immobilizer Problems. On most Models these systems are separate and should therefor also be diagnosed separately.
- In case of Engine Starting Issues please make sure that you are really experiencing an Immobilizer related Problem! On most models using conventional keys, the Engine will still start cut out after 1-3 Seconds if an Immobilizer related Problem is the cause. However, on models using Kessy Systems and electronic keys, most systems in the car won't power up at all if if an Immobilizer related Problem is the cause. If you are NOT experiencing this behavior (e.g. instruments power up, and engine cranks but doesn't fire at all or engine won't crank) this is likely NOT Immobilizer related.
- When found in Audi A3 (8L), Audi A4 (8D), Audi A6 (4B) or Audi A8 (4D), check Wiring from Immobilizer Control Module to Immobilizer Reader Coil. A known issue would be the Length of the Wiring, an optimized Replacement Part may be available (8D0-972-275).
- May be stored in Combination with 17656/P1248/004680 - Engine Start Blocked by Immobilizer in Engine Control Module.
