OBD-II Code
P0293
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$400–$3,500
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
$400 (Mercedes M275 injector + coding at indie shop) to $3,500 (BMW N74 or Lambo V12 injector replacement at dealer with full coding and adaptation reset).
P0293 is the cylinder 11 injector circuit LOW fault — same failure mode as P0290 but on cylinder 11, which restricts the diagnosis to V12 engines almost exclusively (cylinder 11 doesn't exist on a V10).
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P0293 is the cylinder 11 injector circuit LOW fault — same failure mode as P0290 but on cylinder 11, which restricts the diagnosis to V12 engines almost exclusively (cylinder 11 doesn't exist on a V10). The PCM is commanding the cylinder 11 injector to open and seeing current ramp below the expected 0.5-1.5A peak threshold during the injection pulse, which means open winding, high-resistance harness, partial short, or PCM injector-driver failure on that channel.
Cheapest-first ladder
- Confirm cylinder 11's physical location from the FSM — on a BMW V12 (N73/N74, used in 7-Series and Rolls-Royce Phantom/Ghost/Wraith) cylinder 11 is on the right bank rear; on a Mercedes-Benz M275/M279 V12 biturbo (S600, SL600, CL600, S65 AMG) cylinder 11 is on the left bank near the rear; on a Lamborghini/Audi V12 (Aventador, A8 W12 if treated as V12) cylinder 11 is rear-bank.
- Pull the cylinder 11 injector connector and ohm out the winding — V12 saturated-driver injectors typically read 12-16 ohms; piezo direct-injection injectors on the Mercedes M279 and BMW N74 are NOT ohm-testable in the conventional sense and require an inductance-capacitance test with OEM-level scan tools.
- Probe the connector for battery voltage on the power side and use a noid light or scope to verify the PCM driver is pulsing ground on the signal side.
- Swap the injector with an adjacent same-bank cylinder (and re-code if direct-injection) and clear; if P0293 follows the injector, the injector is bad, if it stays on cylinder 11, the wiring or PCM is the cause. The expensive misdiagnosis: don't replace a BMW N74 or Mercedes M279 piezo injector based on an ohm reading alone — these injectors don't respond to conventional resistance tests and a swap-test with proper coding is the only valid diagnostic; condemning one based on a multimeter reading wastes a $1,200-2,200 part.

- 2009-2015BMW N74 6.0L V12 twin-turbo (760Li, Rolls-Royce Ghost/Wraith/Phantom) sets P0293 from piezo injector failure on the right-bank rear cylinders where the turbo heat soak is worst — these injectors are $1,400-2,200 each, must be coded to the DME, and there's a known BMW production cluster around 2010-2012 VINs that fails early.
- 2007-2014Mercedes-Benz M275/M279 V12 biturbo (S600, CL600, SL600, S65 AMG, S600 Maybach) sets P0293 from injector connector failure and from a sub-harness chafe under the engine cover at the rear of the left bank.
- 2011-2022Lamborghini Aventador 6.5L V12 sets P0293 from injector failure on the rear cylinders that share an exhaust-manifold heat path with the catalysts. Note that the Hemi 6.4 SRT, Ford 6.8 V10, and Audi R8 V10 do NOT have a cylinder 11 — if P0293 is being reported on those engines it's a scanner database error and the actual code should be re-pulled with a manufacturer-specific tool.
