OBD-II trouble code
U0467: Invalid Data Received From Fuel Additive Control Module
A module is receiving messages from the fuel additive control module, but the data inside them is implausible or out of range. The link is alive; the content is wrong. Found on diesels that dose additive for DPF regeneration; the car drives normally, but emissions health is at stake.

What does U0467 mean?
The fuel additive control module manages a system found mainly on certain diesel vehicles: it calculates how much fuel-borne catalyst additive to inject into the fuel (typically into the tank when you refuel) and controls when that injection happens. The additive lowers the temperature at which soot burns off in the diesel particulate filter (DPF), so regeneration completes reliably. The module tracks additive tank level, fuel added at each fill-up, and dosing history, and shares all of it over the network with the engine controller. U0467 sets when a receiving module is still hearing from the fuel additive control module, but the data in its messages is invalid — a dose quantity, tank level, or status value that's out of range or contradicts what other modules report. The link is alive; the content can't be trusted, which is what separates this from a lost-communication code, where the module goes silent.
The vehicle remains driveable — the engine starts and runs normally, because the additive system supports emissions equipment rather than combustion itself. The real stakes are downstream: if dosing stops or goes wrong while the fault persists, the DPF regenerates less effectively, soot accumulates faster, and over time you invite DPF-loading warnings, forced regenerations, or an expensively clogged filter. That's why this code deserves attention soon even though nothing feels wrong from the driver's seat. An empty additive reservoir is also worth ruling out early — on many systems the additive is a scheduled service item, and a depleted tank can surface alongside implausible level data.
Causes follow the invalid-data pattern: low system voltage or a poor ground; corroded, loose, or damaged connectors (the module and its pump/injector hardware often live near the fuel tank, exposed to road spray and corrosion); chafed or damaged bus wiring; a faulty additive level sensor or dosing pump feeding the module readings it passes along; software or configuration problems, including a module not coded correctly after replacement or after additive-tank service; and an internal module fault.
Common causes
- Corroded, loose, or damaged connectors at the module or dosing hardware (often tank-mounted, exposed to road spray)
- Low system voltage, a weak battery, or a poor ground at the module
- Chafed or damaged bus wiring corrupting messages in transit
- Faulty additive tank level sensor or dosing pump feeding implausible readings
- Additive reservoir empty or not refilled/reset correctly at service
- Module not configured or coded correctly after replacement or additive-system service
- Outdated, corrupted, or mismatched module software
- Internal fuel additive control module fault
Symptoms
- Check engine or diesel emissions/DPF warning lamp on
- More frequent, longer, or failed DPF regenerations over time
- Additive system warning or service message on the driver display
- Companion DPF, additive-system, or network-communication codes stored alongside U0467
- Engine starts and drives normally — the effect builds in the emissions system, not the driving feel
Diagnostic steps
- 1.Read all stored codes and note companions — DPF-loading or additive-system codes alongside U0467 sharpen the picture.
- 2.Check the additive reservoir level and service history; an empty or recently serviced tank that wasn't reset correctly is a common, cheap finding.
- 3.Load-test the battery and verify charging voltage and the module's grounds.
- 4.Inspect the connectors at the additive module and dosing pump for corrosion, looseness, and bent pins — these often live near the fuel tank in a harsh environment.
- 5.Check bus wiring to the module for chafing and damage.
- 6.With a capable scan tool, compare the module's reported tank level and dosing data for plausibility, and verify configuration/coding if the module or tank was recently serviced.
- 7.If power, wiring, level data, and coding check out, suspect an internal module fault and confirm with service data before replacing.
Repair cost
$100 – $700
Cost depends on the cause. Repairing a connector, ground, or wiring fault typically runs $100-$300. An additive refill service (where scheduled) commonly runs $150-$400 including the fluid. Level-sensor or dosing-pump repairs land in a similar range. Module replacement with coding is the top end at roughly $300-$700. Ignoring the code risks a clogged DPF, which costs far more.

DIY vs shop
This is an advanced DIY job. It typically requires specialty tools, scan-tool access, lifting equipment, or careful sequencing to avoid causing new failures. Plan for extended downtime and have a backup vehicle. Most owners are better served by a shop that has done this repair before.
