A chafed wire in the PT-CAN (Powertrain CAN) or K-CAN (Body CAN) bus behind the dashboard can introduce resistance or short circuits. Mice chewing on wiring near the steering column or footwell modules is a known issue.
Success Rate: 90% (if hardware is bad) If software fixes fail:
If the fault code interpretation does not match your car, consider these edge cases: bmw 2ddd00
Given the fault mapping, these BMWs are the prime suspects:
| Chassis | Engine | Code Likelihood | |---------|--------|------------------| | F22 (2 Series 220d, 225d) | B47D20 | High (2DDD boost) | | F30/F31 320d/325d | N47T, B47 | High | | E90/E91 320d | N47 | Medium | | E82 1 Series 123d | N47S | Medium | | F87 M2 (N55/B58) | N55 | Low (2D00 throttle) | A chafed wire in the PT-CAN (Powertrain CAN)
If you own a BMW 2 Series (F22/F23) built between 2014-2021 with a diesel engine, you are the prime candidate for the 2ddd00 diagnostic trouble code.

You might not notice any drivability issues when this fault is stored. However, depending on the severity of the communication loss, the following symptoms can appear:
