18057 (P1649) Data Bus Powertrain: Missing Message from ABS Control Module
This module has stopped talking on the car's data network, so nothing else can hear it.
Can you drive it? This affects a system that helps you stop or stay straight. Assume ABS and stability control are reduced or switched off until it is fixed.
The definition
18057 (P1649): Data Bus Powertrain: Missing Message from ABS Control Module.
The same fault, the other numbering
The same fault carries two numbers:
- OBD-II P-code equivalent:
P1649
What to check first
Cheapest and fastest checks first:
- Read the freeze-frame data stored with the fault - engine speed, load and temperature at the moment it logged tell you whether this happens cold, hot or under load.
- Check the connector at the part for corrosion, and that it is fully seated.
- Clear the code and see whether it returns, and under what conditions.
Reading the code is the easy part
A code names the circuit that complained. What tells you why is watching the sensor behind it while the engine runs — and that is where a code reader stops and a diagnostic tool starts.
VAGPULSE reads your engine ECU's fault codes and the live measuring blocks behind them, and clears the codes once you have fixed the fault. On the engine it also does what a generic OBD reader cannot on a VAG: coding, adaptations, and Stage 1–3 flashing on Bosch ME7 petrol ECUs, with a backup saved every time it reads your ECU.
