Car will not start, new battery, not starter
Yesterday, after I left work and returned to wait on a coworker, and left the car on accessory to listen to the radio as I waited. After 30ish minutes I go to start the car and the starter goes but the engine won't turn over. Got a new battery but still nothing. Others have said it sounds like the engine was not getting any fuel and my MHD is giving:
2A61 - Ignition relay and injectors, supply voltage, fuel injection: line disconnection 2DB6 - Valvetronic relay, activation: line disconnection 371E - Relay, ignition and injection systems, activation: line disconnection Thinking it's a wiring issue but I'm not that experienced in wiring issues or problems of this kind at all. Nothing out of the ordinary happened before the issue to hint that there was a problem. It's a 2012 BMW 135i and is only has a CP and MHD Stage 1+ Flash Car also makes a clicking noise that sound like it's coming from the dash or rear engine bay when I attempt to start it. Thanks in advance |

This is now a couple weeks old but I haven't noticed it. You may have resolved it but I will comment. The way the starting circuit works is there is a relay, I think it's on the starter for our cars but sometimes it is in the engine compartment, that is triggered when you push the start button. The relay has to handle the large current flow necessary for the starter to work. The relay has a power feed direct off the battery that it switched to turn over the starter. It sounds like you are getting the click from the relay but not the actual rotation of the starter. It could be that you jumped the car and did not get a good enough connection to flow the current the starter requires. If you replaced the battery, then either the electrical connection to the starter relay is bad or the starter is bad. You can jump directly to the starter relay to eliminate that possibility. If you do this, you can also jump across the two lower power contacts that are engaged by the push button on the dash to see if the starter will turn the motor over. Be sure it will not cause damage, however, if the engine turns over or starts - no hands in the way and car well supported, not on a jack.

Okay, so I took it to a trusted mechanic (Euro-Sports in Spartanburg, SC) and it ended up being the distributor box. The ebox in the engine bay was only getting 2v and now it works just fine.

Odd but makes sense. Strange coincidence with it going with listening to the radio for a while. Thanks for the followup - so many threads go unsolved!

It is very odd but in the colder months my car would have long starts, and sometimes stall so maybe that was the issue for that as well? And you're welcome, I wanted to hopefully help someone in the same predicament.

Sorry I didn't see this post earlier, I had a similar issue and it was the relay that is adjacent to the fuses under the glovebox. That's what I traced the clicking noise to and replaced.

Old Guy (64) with Wifes 328i 2008 starting issues
I reviewed some of these answers and I am going to try to fix the car. I live quite a ways from any kind of repair shop or BMW shop.
I have a similar issue as with this post. The car has been sitting up for a couple years now. I had replaced the battery new once to see if she will start. It will only "turn" but never start. I noticed the fuse box in the passenger glove box has corroded. I was going to see about getting a part from somewhere like eBay or other. I most like will have to pump out the old gas and put new gas in it. I was going to go and replace the passenger relay box first. Is this hard to remove out? The next step is someone commented about a Distro box in the engine bay. What and where is this and then how to remove it? Are there any other suggestions I can try? |
