P246E Exhaust Gas Temperature Sensor 4 Bank 1: Electrical Malfunction
- Power Loss/Limp mode
- MIL on
- Glow Plug Light on
- DPF Light on
- EGT sensor faulty
- EGT wiring faulty
- Check EGT sensor and wiring.
- Note, when found in RoW B8 chassis A4 (8K) models with Engine code CAGA which uses the UDS protocol:
- The Advanced Measuring Values for EGT sensors may not be labeled correctly! Make sure to check [*ENG106430*] Exhaust gas temperature before particulate filter even though this is the last (4th) sensor.
- Unplugging the suspect EGT sensor while re-checking the resulting fault codes and evaluating Advanced Measuring Values would be advised before replacing parts.
