If your car is doing nothing when you turn the key:

The biggest and most obvious and most common thing is the battery. Don't think just cause you've got dome lights, your battery is good. E46 is really picky i've learned and requires a big whoppin fully charged battery. I once had my neighbors dead battery E46 on jumper cables with My e46 running AND REVVED and his engine wouldn't even BUDGE. Nothing. Even after 5 minutes and multiple tries. After 10 min, his engine barely (BARELY) turned over. And he limped over to pep boys to get a new battery. all was fine. ive experienced this with other E46s as well. being picky and requiring lots of time and needing full voltage. My cables were fairly thick too.

The second likely culprit is the starter. could be in a bad spot on its rotation. or could just be completely dead.

third culprit (rare) is you have a mechanical jam (mango patent pending term) that means you locked up your engine some how, fast and furious shifting, broke a connecting rod, someone threw metal gummy bears in the spark plug hole. that kinda thing.

seriously try a jump. if you start, get a new battery (you should anyway) and i suppose you could push start the engine.

if not, consider a starter (another "you should anyway")

98% of the time, these cars are not mysterious. people post walls of text and theories, requests for readings this and that.

my opinion is F all that. just maintain the most obvious and simple things and you'll never experience a breakdown/no start. 7 BMWs and 250k driving miles and i never have! GL OP!

So believe it or not I baby this car and put TONS of money into it on a monthly basis. Have done the cooling overhaul, suspension, regular oil changes, replaced the battery with a brand new one less than 2 years ago, o rings, air filter, oil pan gasket, etc etc.

TBH all of my problems started when I got the avin avant 2 installed (android head unit). Started draining my battery. My car was pulling a full amp with engine off (after 20 minute rest period.) Thats when i replaced the battery, then my alternator died out on me and i got that replaced with a higher voltage alt.

In the days leading up to this (even before topping up the oil) the car would crank slugglishly but still start. When it failed to start i was so sure it was the battery but the very first thing i did was to get the car boosted and with cables connected got nothing. Lights were a bit brighter indicating that the battery was problably low because of the head unit (car always turns over sluggishly when I dont do a hard shutdown on the headunit before turning the car off) but ultimately i stopped hearing any clicking and i get basically all dashboard lights on when i try to start the car. the fact that the boost didnt work this time is whats lead me to believe it was the overfill but honestly, I'd love to be wrong. I just want my damn car back

heres a video of latest attempt:

Did your alternator die AFTER you replaced your battery? That's the thing with that, it's a vicious cycle/circle. You can get a new battery due to a failing alternator and that alternator can then kill that new battery. And vise versa if your battery is low. Both can kill eachother if one is weak, and you replace ONE thinking its the problem.

The main thing to do is check your resting voltage. I believe 11.5+ V is what you want when starting your car. Ideally 12-12.3. If you're below that, you either have a charging or parasitic draw problem.

Test battery, test alternator (you can view voltage while running 14.4) and last make sure that HU isn't drawing when car is off.

yea it did...bullocks.

thats what my mechanic mentioned...parasitic draw. he said hed have to test where it was coming from but that my car was definitely drawing way more than it should be in a resting state..don't remember the exact figures.

If this were a battery issue though wouldnt the boost get the car started?

If your mobile mechanic wants some ideas, this might help him. But then again it might cut down on his fee. http://forum.e46fanatics.com/showthr...eplacement+diy
BTW, the starter is under the cabin filter, near the fire wall, not the airbox.

I just said **** it and enrolled with CAA Premium and will get it towed out to my mechanic in Mississauga most likely whos always done good by me

Start at the bottom holding the key in the start position and slowly push the lever up to park.

The starter sits on top of the engine near the middle of the block, pretty much under the intake manifold.

I hope before you mechanic changes the starter he tries to turn the crank with a socket and breaker bar. The red oil light isn't a good sign.

i will ask him to. what are you thinking the red light could indicate? i know it means pressure issue but dont those dash lights always act wonky when there are power issues? e.g the parking brake light is on but the brake is down.
