How much does P0280 cost to fix?

One fuel injector is $768 – $953 (one fuel injector replacement, parts and labor, after the 2010 M5 plug-and-harness step or the 2007 E-350 6.0L high-current result; the short, the DME, and a FICM are outside this pair). RepairPal's 3 September 2026 national average is parts and labor after the M5 plug and harness check or after the 6.0L high-current result. The short, the DME, and a FICM are not in the pair. Diagnosis is $125–$183 and is separate.

Why do two M5 pages share hex 276D?

The 2008 page is P0279, short to ground, 3500 rpm. The 2010 page is P0280, short to B+, 5000 rpm. The hex identifies the cylinder slot on those pages. The SAE code and the memory line identify the fault.

Should I ohm the injector to 12–16 ohms?

The 276D page does not print that range. 12–16 ohms is the 2008 G8 coil test, and that chart does not include cylinder 7.

A 6.0L stored P0280. Is that a short to B+?

Not on the 2007 E-350 6.0L FICM fault list. There P0280 is cylinder 7 injector circuit high, high current from a shorted coil or a short to ground. The short-to-B+ memory line is the 2010 M5. The 'ie' high-code examples are not a list that omits cylinder 7.

Can I drive with P0280?

The badge allows a short trip. The 2010 effect line includes a 5000 rpm limit and reduced power. Depressurize before the valve is removed.

OBD-II trouble code

P0280: Cylinder 7 Injector Circuit High

SAE J2012 APR2002: cylinder 7 injector circuit high. The 2010 M5 S85 stores a short to B+ under hex 276D. On the 2007 E-350 6.0L the FICM fault list files a short to ground. The printed pair is one injector after the harness step.

What does P0280 mean?

SAE J2012 APR2002 names P0280 Cylinder 7 Injector Circuit High. A VAG-group list prints 16664 P0280 as injector 7-N85, short to positive. The G8 chart does not list P0280. P0279 is the circuit-low code.

The 2010 BMW M5 (E60) S85 page files 276D - P0280, electrical diagnosis of cylinder 7's fuel injector. Conditions: driver info present, terminal 15 on, battery voltage above K_ED_PlusMin. Memory: the driver info includes a short circuit to B+. The action is still two steps, in order. Check the plug and the wiring harness on the injection valve. Then check the valve and replace as indicated. The breakdown line is rough idle, engine speed limited to 5000 rpm, power reduction, and the MIL after the engine runs twice.

The 2008 M5 page uses the same hex 276D for P0279. That memory line is a short circuit to ground, and the speed limit printed there is 3500 rpm. Using the 2008 page on a 2010 car, or the reverse, swaps the fault direction and the rpm figure. The 2007 E-350 6.0L FICM fault list names P0280 Cylinder 7 Injector Circuit High under short to ground and high current: a shorted coil or a short to ground. The 'ie' line, from P0262 and P0265 through P0283, is only examples of that group. That mapping is the 6.0L V8, and the list stops at cylinder 8, so cylinders 9, 11, and 12 stay off it. It is not the 2010 M5 memory line, which is a short to B+. Do not use the diesel current test on the M5, or the M5 B+ sentence on the 6.0L.

No resistance spec is printed on 276D. A coil measurement without the car's own limit is not a pass or a fail.

Common causes

On the 2010 M5, a short circuit to B+ in cylinder 7's injector driver info, fault 276D
A short to B+ in that injection valve's plug or harness
On the 2007 E-350 6.0L, a shorted coil or a short to ground, the high current the FICM fault list files as P0280

Symptoms

P0280 stored
On the 2010 M5 page, engine speed limited to 5000 rpm
Rough idle and a power reduction on that same effect line
MIL after the engine runs twice
P0279 stored, which is the other year's use of hex 276D

Diagnostic steps

1.Match the model year. 2010 and hex 276D is this short-to-B+ code. 2008 and hex 276D is P0279.
2.With terminal 15 on and voltage above K_ED_PlusMin, inspect the plug and the harness on cylinder 7's injection valve. Repair what that inspection finds before the valve is discussed.
3.Replace the valve only as the page's second step indicates. The 5000 rpm figure is the fault effect, not a road-test target.
4.On a 2007 E-350 6.0L, P0280 is high current from a shorted coil or a short to ground. Do not run that current test on the M5. The 2008 page for hex 276D is P0279. The G8 chart does not list P0280. The 6.0L fault list stops at cylinder 8.
5.Depressurize before the valve comes out. The printed pair is one injector. The B+ short and the DME are outside it.

Repair cost

$768 – $953 (one fuel injector replacement, parts and labor, after the 2010 M5 plug-and-harness step or the 2007 E-350 6.0L high-current result; the short, the DME, and a FICM are outside this pair)

The national RepairPal injector job updated 3 September 2026 is $768–$953, of which labor is $304–$446 and parts are $464–$507. Printed here as the valve the 2010 page replaces as indicated, not as a diagnosis and not as a DME. The 2026 F-150 injector line at $1,130–$1,415 sits outside the national pair. Diagnosis at $125–$183 is labor only and is separate. No separate M5 injector total was found on that estimator.

DIY vs shop

Leave this one to a qualified shop. The barrier here is high-pressure fuel components, where residual pressure remains after shutdown and escaping fuel can penetrate skin. DIY attempts often produce a more expensive problem than the original code.
