Battery is good, replaced IBS. Was driving under engine malfunction then pulled over to read codes, this one keeps appearing. Car will not start.


Terminal 87_2 no voltage 332F

Any ideas?

Terminal 87_2 no voltage 332F
[WHAT about other 8 codes you show? Did they occur at same time/ mileage as "car will not start"? Did you Clear them without reading/saving FF Data? SIX (6) of the other codes relate to Short Circuits, so you probably blew multiple fuses related to the DME Relay powered "Power Supply" for the DME]
Any ideas?

IDEAS:
1) Answer the questions above, PLEASE.

1a) Bonus Question: Did you have some event under the hood just BEFORE all this happened, such as shredded Serpentine Belt taking out wiring?

2) See BMW Fault Code Lookup Definition below for FC 332F for your N55 Engine (I presume?):
N55 | P15ED | 332F | Terminal 87_2: No voltage | MEVD17KW

3) See BMW Fault Code Lookup Fault Information for Fault Code Description, basic identification of Relays & Terminals (Terminal 15, Terminal 87) and "Service Plan":
http://www.bmwfault.codes/XMLDiagVie...EAOAA5ADAANAA=

4) See TIS circuit diagrams for DME Power Supply, Valve Gear, & Oil Supply, Oil Pressure Control Valve (Y6384), showing multiple components for which short circuit codes are displayed:

Please let us know what you find or questions regarding testing, such as how to test circuits for shorts, WITHOUT blowing fuses to test (measure resistance instead -- near 0 resistance in reference to ground indicates short to ground).

I was driving and while sitting in traffic, the car triggered engine malfunction. Power reduced.

The car will crank, and start but stalls after a second or so, never idles.

The screenshot is the lines of codes that appeared after i pulled over. Before my trip i had no codes, i had checked.

All the other codes related to sensors re-appear when the car runs and stalls. When i reset the codes just terminal 87_2 no voltage, appears.

So i reviewed my engine, serpentine belt is good. The wiring that runs near the front of the engine by VANOS solenoids, near the water pump/thermostat were all wet and covered in coolant.

If I am correct, all the sensors that are shorting are on the same wire harness.

I am in the process of replacing the pump and thermostat i've had them on hand for some time.

Drying off the electrical connections and wiring too.

The DME diagram helps but don't see how it gets to X600003

Fuse 37 was blown.

15 amp

Late to the party but this post helped me. Did some work this weekend and after putting everything back together, no ignition. Had about 8 scary codes. Short circuit seemed to be the theme so I wasn't worried that I'd destroyed something, but I was worried that I would be tracking a wiring issue. Luckily, it was fuse 36, 15 amp. Replaced that and all good so far.
