Overview
The control module stored C1250 because it detected a problem with: ABS Inlet Valve Coil LR Circuit Failure.
C1250 relates to ABS Inlet Valve Coil LR Circuit Failure. Use a quality scan tool, follow wiring diagrams for your vehicle, and confirm tests before replacing expensive parts.
What does the C1250 code mean?
When C1250 is set, the vehicle’s diagnostics detected an issue described as: ABS Inlet Valve Coil LR Circuit Failure. In practice, the ECM/PCM (and related modules) compare sensor inputs, commanded outputs, and self-tests for that subsystem. The exact repair depends on whether the fault is wiring-related, component-related, or a rationality/performance issue for this circuit or system.
Common symptoms of C1250
- Misfire felt at idle or load
- Poor fuel economy
- Flashing MIL under load
- Hard start
- Check engine light
- Power loss
Possible causes
- Fault affecting ABS Inlet Valve Coil LR Circuit Failure (wiring, connector, or component)
- Component failure in the described system
- Control module strategy or calibration issue
- Electrical fault in the monitored circuit
- Control module or software calibration issue (less common—verify tests first)
- Past repairs or aftermarket parts causing out-of-spec operation
How to diagnose C1250
- Scan for C1250 and review freeze frame / pending codes for related faults
- Inspect connectors and wiring related to: ABS Inlet Valve Coil LR Circuit Failure
- Compare live data and commanded vs actual values for the affected system (per service information)
- Perform circuit tests appropriate to the fault type (continuity, voltage, resistance) before replacing parts
- Confirm power and ground integrity at the relevant module or sensor
- After repair, clear DTCs and verify under the conditions that originally set C1250
Tip: Use a scan tool that shows live data and freeze frame for the conditions when the code set.
Severity of code C1250
Moderate: Have this code diagnosed soon; ignoring it can lead to worse fuel economy, repeat failures, or secondary damage.
Can you drive with C1250?
Short trips may be okay if the vehicle feels normal, but have it diagnosed—especially if performance, safety warnings, or overheating are present.
Avoid heavy acceleration, towing, or long highway drives until the cause of C1250 is confirmed and repaired.
How to fix it (step-by-step)
- Start with visual inspection and connector cleaning/tightening where needed
- Confirm failure mode with testing—avoid swapping parts without evidence
- Repair wiring or replace the failed component per manufacturer procedure
- Clear faults, run relearns if required, and road test to confirm
Repair & fix options
- Inspect connectors and wiring first
- Test component against service limits
- Clear codes and verify with drive cycle
- Clear codes and verify repair with a drive cycle and readiness where applicable
- Reinspect related monitors if the code returns after repair
Typical repair cost
$100 – $2,000+ depending on cause

How to help prevent C1250 in the future
- Fix new codes early before secondary damage or catalyst stress
- Keep connectors clean and secure; address rodent or water intrusion in harnesses
- Use the correct fluids/parts for your vehicle and service intervals
- Avoid ignoring pending codes after battery work or repairs
When to see a mechanic
Schedule diagnosis if the check engine light is on, drivability is worse, or you notice new noises, smells, or warning lamps. For safety-related (SRS/ABS) or overheating symptoms, prioritize a qualified shop immediately.
Common mistakes when diagnosing C1250
- Replacing sensors/modules without verifying wiring and reference voltages
- Ignoring related codes that identify the real root cause
- Clearing codes without a verification drive cycle
Common vehicles & notes for C1250
- Volkswagen / BMW models (common examples—verify for your vehicle)
- Mercedes-Benz / Audi applications vary by engine and model year
- Many other makes—this is a standardized OBD-II definition: ABS Inlet Valve Coil LR Circuit Failure
C1250 is reported across many platforms including Volkswagen, BMW, Mercedes-Benz, Audi. Always use VIN-specific service information for testing limits and calibration steps.
Frequently asked questions
What does C1250 mean?
C1250 indicates a fault involving ABS Inlet Valve Coil LR Circuit Failure, based on what the control module detected during self-tests or live monitoring.
Is it safe to drive with C1250?
If the vehicle runs normally and no warning lights are flashing, short trips may be reasonable—but avoid ignoring symptoms like misfire, overheating, ABS/SRS warnings, or major loss of power.
How much does it cost to fix C1250?
Typical repairs often fall in the ranges shown on this page, but final cost depends on labor rate, parts quality, and whether the issue is wiring vs. a major component.
What is the most common cause of C1250?
Most shops start with wiring/connectors and the directly monitored component for “ABS Inlet Valve Coil LR Circuit Failure,” then expand testing if the fault returns.
Will C1250 clear itself?
It may become intermittent, but if the underlying fault remains, the code will usually return—especially after a drive cycle.
Can a weak battery cause C1250?
Low system voltage can cause odd sensor/module behavior, but you should still validate the actual DTC and perform normal circuit/component tests.
