There were a number of alternative 'translations' for this code, all dealing with a short circuit to ground.

If you don't have a good led flashlight, I'd get one. And although I have a multimeter, I never really took the time to learn how to use it for other than reading voltage, but you can get one for $20 and spend some time learning/hunting.

Also...other than reading a code, what symptoms does your car have? Is your cel on? Is it running poorly?

Simple rule when it comes to BMWs.

If you have to ask what a fault code means, then you are over your head.

Have a professional deal with it.

Super helpful response there...Him simply asking what it means is not the same as him asking how to fix it. If he wants to try to educate himself so that when/if he does have to take it to the dealer he can have a better understanding of what is required to fix, and an idea of what the cost may be to do that repair. Isn't that kind of the point of these forums?

Par for the course.

A simple Google search would have provided an answer to what the fault meant without a delay of half a day from his posting.

His wording of the stealership further defines his level of expertise.

We all have to start somewhere, dude. I'm sure there was a point where you weren't as well versed in all things BMW as you are now.

1 big difference.

I was willing to use a simple forum search and Google, both which return results on the initial question.

I wasn't waiting for someone to spoon feed me.

Furthermore, if one reads the code meaning and what it applies to, it's nothing a newbie should be dealing with unless you want to destroy your DME.

So it actually was the correct answer.

yes you are right I dont know much I do have other codes and I would love to be able to fix it myself however I cant and am going to the dealership today and dont want to get robbed. if I pay for the diagnosis do they have show me it ?

there are short cut to ground codes.

battery is good.
vanos soleniod inlet and outlet show short circuit to ground or earth.

auc sensor as well

like I said just want to make sure l have an idea of what's going on.

thought it might be a relay
or a wire.

Google doesn't tell you everything I have been reading lots of searches on everyrhing related. not sure why you mentioned a flashlight.
car still starts bur shows drivetrain malfunction. I also tried to install ista+ into an old laptop but it didnt work to see it I could fix the issue. so yes I'm biting the bullet. and taking her into the dealer today. at 1. thanks for the responses.

I'm not asking you to spoon feed. me. I learn a lot from these forums. I also see the arrogance in people as well.. feel free to google it. it took me lots of searches to find out the code for 15n short circuit into ground could be as simple as ignition being an issue. you may think I'm trying to be spoon fed the answers however I research this stuff all the time and I love my car and would fix it myself If I could. when I ask a question. and say any help would be appreciated that's all I'm asking for. believe me I have downloaded pdfs and mechanical guides for the N20. and fear the timing. chain guide curse happening for these engines. you have your opinions I have mine. regardless of my mechanical skills.

If you have really read these forums, you find weekly threads from people who have turned a minor issue (or no issue) into a major issue by thinking they can code their car.

When you get to the DME coding, that is far beyond most members.

And if you cannot find the error code meaning, is well beyond your abilities unless you want to make your costs exploded like the Covid19 infection rate.

[dmaxdmax]

OP, I agree you (or most of us) shouldn't be messing with the DME, but I mentioned flashlight so you could look to see if there are any wires you can see that are broken or rubbing against something.

Often, not always, voltage issues can come down to a loose/corroded connection. Or, if this fault showed shortly after you did something else on the car, it can narrow your search down...and sometimes you find something even if you don't know anything about cars.

Good luck at dealer. Let us know what it turned out to be.

only codes done to it where bimmcode codes for mirrors. and unlocks I wanted insta+ for diagnosis only not insta p. rhis all happened after thermostat housing was changed and the oil was changed. a week later the drivetrain malfunction showed up. I just miss my car. if we didnt love these cars we wouldn't be on here.

lol to the covid 19 reference. I have to get my notifications setup on here so I can respond more promptly.

Not to mention the link I provided right before that pertaining to a similar issue/resolution in the F10 forums.

Also, I don't consider 22 hours beforehand to be "immediately prior".

the tech noted "need to start with the integrated supply module. if that does not fix the issue it could need dme as well . then they told me how my timing chain will need to he replaced and a possible bill of 9k US dollars to fix the whole thing. the service manager was not enough to show me the location of both parts. what a day.

[dmaxdmax]

Just know what the warning signs of a timing chain going are and don't worry about that bill just yet...and the 'integrated supply module' sounds like a battery.

Not sure if you're familiar with realoem.com and I'm sure you can get to the dme supply module with help from the TIS. I think shops will frighten you into saying 'DME' so you're then grateful when it's only $500 to replace a hard to get to $50 battery.

ok do you mean battery in dme ? as for as the battery itself for car it's good. I'm looking into my gfs mechanic eventually doing the timing stuff cause the body is in awesome shape. and as mentioned before I am a rookie. but if I can fix it I will. tg i have a Silverado I can drive as well.

I'm 'guessing' that the supply module is a fancy name for a battery, but it might be some sort of transformer? See if something comes up in realoem under engine electronics.

Here's 'a' supply module under vehicle electric (in my car, not yours)...but I bet you have something comparable.

Not sure how pricey it is to 'guess' that the tech's guess might be right...but hope this gets you closer to finding out.

this is the part. and if this doesnt work they say its DME. they wanted 385 alone. to replace that $123.00 part.

well different dealer said it was a bad ground wire. and then three days later when their tech came back to work on my car they called me and told me there is a hard fault in the icm. so after 2 hours Alberto diagnose. its going to be 2650 to replace icm. and problems should all go away.

Did you find what the problem was?
I have the same issue doesn’t say anything
