Electrical issue in my M3...any advice?

So my only mods are angel eyes, an air filter (drop in) and LED taillights. nothing major.

the other night i was late to my gig, my car wouldn’t start, and i had to get a jump. i smelled something burning, pop the hood, and the lead going to the battery terminal was MELTING. so i turned the car off…pulled the fuse
for the angel eyes, and resumed, got the car home. no problems.

today i get up and i’m like alright time to figure this shit out. i go outside, pop the lead off the terminal with a hex wrench, shit is melted - the wire is brutal. the angel eyes work real simply, the battery terminal lead goes to the fuse (which didn’t blow?) and to a relay, while a wire heads to the ECU to tell it to turn on with the car. that’s a wire tapped, nothing crazy. the wires then head to the eyes themselves, located inside the headlights of course.

so yeah, then i pop my trunk to check to see if my battery is fucked. sure enough, my battery is leaking now. car drives fine but i don’t want to fuck anything up. i called bmw, my car’s a CPO for another whopping month (ha). i have full coverage down to the wiper blades. i have no idea how, but last time i went in there the lady did everything short of a handjob for me - excellent service.

so…should i just hide the wires for the eyes, and tell them my battery randomly popped? they noticed the eyes last time because i asked them about my xenon ignitor that sometimes gets pissy and won’t ignite, but short of that, i don’t see why that’d be a problem. worse case, csl battery.

edit: i realize the wire melted because of drawing too much current for that gauge wire. does that mean the battery maybe overheated or something? the angel eye kit shouldn’t fail…it’s been on the car since i bought it pretty much…

advice?

if you buy a “csl battery” i will kick you in the nuts next time i see you…

You just buy a mini cooper S battery if you want a smaller/lighter one… it saves MAYBE 8 lbs…

I run an optima red top… i love it

What kind of angel eyes do you have? most of the kits have garbage ignitors that do dumb shit like this all the time…

i was gonna say check your ignitors, because this sounds like exactly what would happen if it went bad. Just fixed this on a customer’s A8. One ignitor went and started melting the harness wreaking havoc on the headlights. We simply pulled the kit and put stock bulbs in and all was well.

orion V2s…led halos…with no ignitor. i explained the signal path above. my stock HID ignitor is “slow” though - sometimes i have to turn my headlights on/off a few times to get my drivers side headlight on…been like that since day 1. think that would do it?

csl battery = cooper S battery…no need to kick me in the balls that’s what i meant…same shit essentially

I duno if the slow ignitor would do it, but it seems odd… mine has never been slow… may want to pull the angel eyes completly and take it into get the ignitor changed before warranty is up

yeah when I took it in the service advisor said the “tech noted aftermarket wiring” but will replace the ignitor if it fails completely as long as the eyes aren’t a part of it - they could not reproduce the problem, go figure haha…it’s very selective about when it does it haha.

Def a good idea. There should be no major time difference between them and having to move the switch a few times was exactly what the A8 was doing. every now and then he could get them both to come on. Stock swap and off to the dealer would be my plan of attack.

alright. fuck man. that shit was a pain in the ass to put in, with this cold ass weather.

try redoing the grounds on the battery and stuff and see if that cures it…

it also may be the bulb… when HID bulbs start to die they take a while to come on if at all… my audi did that… thought it was the ignitor, turned out to be just the bulb… try switching bulbs from one side to the other and see if the problem follows

I switched the bulb when I first got the car. It’s certainly the ignitor.

common issue with any Umnitza products… pull that shit off and stop with the angel eyes crap… there are cases of them starting the car on fire search M3forum for the threads

yeah, thats probably the best advice. garbage products…fuck. i spent like 140 bucks for something to start my car on fire and kill my battery. phenomenal.

on another note… i have 0 problems with my ebay angel eyes/ballasts and custom wiring…

i called umnitza and the guy was like “CHECK YOUR INSTALL THESE PRODUCTS HAVE NO FAULTS”

i took pics, and needless to say it’s not hard to wire two wires up. i’m thinking about mailing these fuckers back, getting my money back and buying a cooper S battery. i doubt these assholes will give me a refund.

If you have pics of the properly installed kit and then pics to prove the carnage, Id say you have a good case.

he wont, he is famous for pulling this shit…

have fun, post this on M3forum…

EDIT: There have been multiple threads, they magically disappear…

alright. fuck this internet drama shit…lol

omg dont even try to deal with them douche bags at umnitza. its never there deffective shitty product.:banghead:

habbie and matt are the worse pieces of shit ever. I hope they die in a fire from a defective igniter.

I have read countless stories just like this on e46fanatics, ditch the angel eyes.

if a wire is melting and not blowing a fuse, something is wired wrong, or you have a bad fuse…
