P1514–P1515 Intake Manifold Change-Over Valve 2 (N261) - Short to Ground
A wire in this circuit is touching the car's metal body, so current escapes to earth instead of reaching the part.

Which code is which
Same fault, different cylinder or bank — diagnosed the same way. Several set together usually means one shared cause.

P1515 | Intake Manifold Change-Over Valve (N156) - Short to Ground | Investigate soon |
The definition
P1514: Intake Manifold Change-Over Valve 2 (N261) - Short to Ground.
P1514 is a manufacturer-specific powertrain code (the engine or gearbox). Its meaning is set by the carmaker rather than by the SAE standard, so a generic OBD-II reader will often show it as an unknown code or misread it.
What to check first
Cheapest and fastest checks first:
- Unplug the connector at the part and measure resistance from each signal pin to a good earth. A healthy circuit reads open, not a few ohms.
- Follow the loom for chafe points - where it crosses a bracket, passes an edge, or flexes near a hinge or the engine mounts.
- Look for water or corrosion in the connector. A wet plug shorts pins to each other and to the body.
What actually causes this on a VAG
Some VAG engines use two intake manifold change-over valves - either because the manifold has two stages, or because a V engine has one per bank. N261 is that second valve, a small vacuum solenoid that moves the flap inside the inlet manifold. "Short to ground" means the ECU sees the valve's circuit pulled to earth, which is either a damaged wire touching metal somewhere or a shorted winding inside the solenoid. Like the first valve, expect a small dent in low-down or top-end pull rather than anything dramatic.
Most likely causes, in order
- Chafed wire touching earth. The classic cause. Look anywhere the loom is pulled tight over a bracket, a manifold stud, an engine mount or a coolant pipe, and anywhere it has been disturbed at a previous service. Wiggle the loom in sections with the ignition on and the fault memory being watched - the section that makes the fault reappear is the section to open up.
- Water or corrosion in the connector. These plugs sit in the engine bay where they get sprayed from below and steamed from above. Unplug it and look for green corrosion on the pins or a seal that has perished and let water in. A corroded pin can bridge to the adjacent one and read as a dead short.
- Solenoid winding shorted internally. The valve's coil can break down and short to its own body. Confirm it with the unplug test below rather than by replacing the part speculatively.
Worth knowing: There is a free test that separates the valve from the wiring: unplug the valve, clear the fault memory, and run the engine briefly. If the short to earth is still reported with the valve disconnected, the fault is in the loom or the connector and a new valve will not fix it. You should expect a different, open-circuit style fault to appear while it is unplugged - that is normal and simply means the ECU can see the valve is missing.
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 every module in a VW, Audi, Skoda or SEAT — not just the engine — shows the live measuring blocks behind this fault, gives you the freeze-frame conditions it was logged under, and clears it once you have fixed it. It also does what a generic OBD reader cannot on a VAG: service resets, coding, adaptations, and Stage 1–3 flashing with your original file saved first.
