P0214 – Cold Start Injector 2 Malfunction (OBD2)

P0214 means "Cold Start Injector 2 Malfunction". Fuel injectors are electrically controlled valves that spray fuel into the engine; these codes mean the control unit has detected an electrical or balance fault in an injector circuit.

How fuel injectors and their circuits work

Each injector is opened by an electrical pulse from the engine control unit. Port-injection petrol engines use 12 V solenoid injectors; direct-injection petrol and common-rail diesel engines use high-voltage solenoid or piezo injectors controlled by special driver stages, sometimes in a separate injector control module.

The control unit monitors the current in each injector circuit. Codes P0200–P0212 report a general injector circuit fault for a cylinder, P0261–P0296 separate low and high faults per cylinder, and 'contribution/balance' codes mean that one cylinder contributes more or less power than the others, usually because the injector delivers the wrong quantity.

An injector circuit fault normally causes a misfire or rough running on that cylinder. Causes range from a damaged connector or wire to a failed injector coil or, on diesels, a worn injector that leaks or delivers the wrong amount. On direct-injection engines, injector work requires care because of the very high fuel pressure.

On VAG vehicles (VW, Audi, Škoda, Seat, Cupra), VCDS and older VAG testers can show this code as the five-digit VAG code 16598 (P0214). Both numbers mean the same fault.

Symptoms of P0214

  • Check Engine light on
  • Misfire or rough running on one cylinder
  • Loss of power, hesitation
  • Higher fuel consumption or smell of fuel
  • Smoke from the exhaust (diesel), hard starting

Most common causes of P0214 (most likely first)

Mechanic's Pro Tip

On diesels and direct-injection engines, always note the correction code printed on the new injector and enter it with the scan tool after fitting. An uncoded injector delivers the wrong quantity and can bring back the balance code – or cause smoke and rough running.

  1. 1.Damaged injector connector or wiring

    Most likely

    Heat and vibration crack connectors and wires on the injector harness.

  2. 2.Failed injector coil or piezo element

    The injector no longer opens correctly.

  3. 3.Clogged or leaking injector (balance faults)

    Deposits or wear change the delivered quantity; diesel injectors can also leak back too much fuel.

  4. 4.Fault in the injector driver or injector control module

    On some diesels the injectors are controlled by a separate module.

  5. 5.Low compression in the cylinder (balance faults)

    A mechanical problem makes the cylinder contribute less, which the control unit can misread as an injector fault.

Step-by-step diagnostic guide

  1. 1

    Read codes and misfire data

    Read all codes, note the cylinder and check for misfire codes or injector correction values in live data.

  2. 2

    Inspect connectors and wiring

    Inspect the injector connector and harness for damage, corrosion and chafing.

  3. 3

    Measure the injector

    Unplug the injector and measure its resistance; compare with a neighbouring injector and the specification.

    Multimeter: High-impedance port injectors: about 11–16 Ω. Low-impedance and many diesel solenoid injectors: around 0.2–3 Ω. Piezo injectors cannot be checked reliably with an ohmmeter – use the scan tool tests.

  4. 4

    Run injector tests

    Use the scan tool's injector balance, quantity correction or cylinder cut-out test. On diesels, a leak-off (return flow) test shows worn injectors.

  5. 5

    Repair and code

    Repair wiring or replace the injector. On many diesels and direct-injection engines, new injectors must be coded to the control unit with their correction code (IMA/IQA/C2I).

Frequently asked questions

Can I keep driving with P0214?

Only gently. An injector that does not open causes a misfire; one that stays open can flood the cylinder, wash oil off the cylinder wall and damage the catalytic converter. Have it checked promptly.

How much does it cost to fix P0214?

Typical repair costs are 20 € – 1500 €, depending on the cause and the vehicle. The most common fixes are: damaged injector connector or wiring; failed injector coil or piezo element; clogged or leaking injector (balance faults). Always confirm the cause with the tests above before buying parts.

Can I clean a faulty injector?

Port injectors can often be cleaned by a specialist with ultrasonic cleaning. Electrical faults and worn diesel or direct-injection injectors cannot be fixed by cleaning – they need repair or replacement.

What does 'contribution/balance fault' mean?

The control unit compares how much each cylinder speeds up the crankshaft. If one cylinder contributes much more or less than the others, it stores a balance fault – usually caused by an injector delivering the wrong quantity, sometimes by low compression.

What is the difference between P0214 and similar codes?

P0214 belongs to a group of codes for the same component that differ in the type or location of the fault: P0211 – Injector Circuit Malfunction - Cylinder 11; P0212 – Injector Circuit Malfunction - Cylinder 12; P0213 – Cold Start Injector 1 Malfunction; P0261 – Cylinder 1 Injector Circuit Low; P0262 – Cylinder 1 Injector Circuit High; P0263 – Cylinder 1 Contribution/Balance Fault. The tests on this page apply to the whole group; the type of fault tells you where to start.
