OBD-II trouble code
P0289: Cylinder 10 Injector Circuit High
SAE J2012 APR2002: cylinder 10 injector circuit high. The VAG list says short to positive on injector 10-N300. The M5 page read for this cylinder is the low code. The printed pair is one injector if the chart replaces the valve.

What does P0289 mean?
SAE J2012 APR2002 names P0289 Cylinder 10 Injector Circuit High. A VAG-group list prints 16673 P0289 as injector 10-N300, short to positive. The line above it, 16672, is P0288, the same N300 designator, short-circuit to ground. Two labels, one designator, opposite directions. The list does not say which pin is the driver and which pin is the supply.
The only BMW M5 S85 page read for cylinder 10 is the 2009 document 2770 - P0288. Memory there is a short circuit to ground, effect line 3500 rpm. That is the low code. It is not a source for P0289's memory line, rpm limit, or hex. A P0289 chart title did not come back in the S85 search, so none of those fields is filled in from a neighboring cylinder. Other M5 high-code pages that were read, such as 2008 P0274 and 2010 P0280, do say short to B+ and 5000 rpm, and they name their own cylinders. Copying that pair of facts onto cylinder 10 would be the generalization those pages do not authorize.
G3 terminals, G8 timing, and the 6.0L current split are engines that do not have this code in the procedures read. On the M5 pages that were opened, the plug and harness are checked before the valve is replaced. That sequence was not read on a P0289 page and has to be confirmed there. Cylinder 10 is whichever injector the numbering diagram marks as 10.
Common causes
- On the VAG-group list, a short to positive on injector 10-N300
Symptoms
- P0289 stored
- P0288 stored, which has the 2009 M5 page and the 3500 rpm line
- No speed limit is given for P0289, because that effect line was not read
Diagnostic steps
- 1.Keep P0289 off the 2770 page. That page is short to ground, 3500 rpm, P0288.
- 2.Number the cylinders from the diagram before a connector is opened.
- 3.Follow this vehicle's injector-circuit chart for a circuit-high test. Do not import G3 pin 1, the G8 2.6–4.6 volt pull-up, or the 6.0L high-current rule.
- 4.Where the opened M5 pages apply, the harness is step 1 and the valve is step 2. Confirm that split on the P0289 document. It was not in the set read for this pass.
- 5.Depressurize before a valve comes out. The printed pair is one injector when the chart calls for the valve. Wiring stays outside the pair.
Repair cost
$768 – $953 (one fuel injector replacement, parts and labor, only when this vehicle's chart replaces the valve after the harness test; the 2009 M5 page read was P0288, and wiring is outside this pair)
The RepairPal national injector total of 3 September 2026 is $768–$953, labor $304–$446, parts $464–$507. It is printed for a valve the vehicle chart actually replaces. The 2770 procedure that was read replaces a valve for P0288, not for this code, so the pair is not described as that page's step 2. Wiring and a DME are outside. Diagnosis is $125–$183, separate. The 2026 F-150 line at $1,130–$1,415 is not the national average.

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.
