Hey Markie,

Does the vehicle crank but just won't start?

About two weeks ago on my 2007 X3 (111,000 miles) I had the problem where it would crank but just wouldn't start. I tried jumping it, but that didn't help either. I had it towed to the nearest BMW dealer, 90 miles away. They determined it was a bad fuel pump.

Once it was replaced, I was good.

If I had've known that it was the fuel pump, I could've replaced it myself for around $300.00. But since I had no clue if it was the fuel pump, a sensor, or several other random things, I really didn't have a choice but to tow it in. The final cost for the pump and labor was $820.00.

What's up with newbies not even saying hi :)

So what I get is that you turn the key and nothing happens, but you have power? My two guesses are starter or battery.


Hope this helps.

I will add 1 more less likely guess - the immobilizer.

Try the other key in case that one has suddenly lost its chip coding.

But could also be the system (EWS) that reads the key and communicates with the computer to signal that the starter (and fuel pump, etc.) can be energized.

However, starter motor is the prime suspect - failures in later model X3's are not unheard of.

These are the 3 things that will prevent a jump start from working, although for the battery to be the culprit it would have to have suddenly developed a complete internal breakdown.

timarnold 11-27-2012 09:23 AM

There is one other possibility. I had the problem on an intermittent basis where everything would power up, but the starter would not turn. I was fairly sure it was the immobilizer, but in fact it was the ignition switch.

Markie seems to have disappeared as quickly as he came.

Very hard to help people when they don't give you much to go on and don't let you know if and how it got resolved.

Interesting... my 07's battery died five years on the spot! Seems like a trend... :dunno:

Markie 11-27-2012 11:14 PM

Thanks guys for the info.. I tried using a different and it still won't start and it's not cranking up

Markie 11-27-2012 11:15 PM

I have an 05 3.0i. Mine had the same exact symptoms as you describe. Wife started it, then it instantly sputtered and died. Wouldn't start for a week. I checked the fuel pump, pressure, crank sensor etc. it was only flooded! 4 plugs were soaked. Dried them off and it started right up. My only concern is figuring out how it flooded. Anyway it drives fine now.

br7478 10-12-2016 12:00 AM

I have a 2007 x3 0si About once a month it will no crank no start, all the lights, windows, etc works. No sounds from starter. This is after driving awhile. I have new high amp battery. After about 1 hour it starts right up perfect. I would love your input. New to this site so my email is butchralston@gmail.com Hope I,m doing things right on here. thanks a bunch

How many miles are on the car? The starters on these cars can fail in stages, so if a jump isn't working starter diagnostics are next.

The starters on the N52 engine (2007- on) are really tough to swap.

The original thread is four years old, and the only ones who stick around that long are the ones too infirm to move, like me.

br7478 10-12-2016 12:23 PM

The car has 135k. I'am a retired mech. But not a BMW mechanic. I sure hope you can help me. Thank you!

I've got the same issue on a 2004 X3 (manual transmission). With the key in, dash lights up normally. Turn the key (2 different keys), and the headlights dim, but no sound at all. Battery shows 12.5V.
Am I correct in assuming that if I can push start it, then it probably is the starter, correct??

I have a 2007 BMW X3 3.0. I drove the car about 250 miles with a couple stops yesterday. As I got home, I tried the key to get into the back hatch. It would not work. I started trying other buttons on the key and they would not work. I tried starting the vehicle and everything was completely dead. I have tried re-setting the key an nothing has worked. Any Ideas?

esbaylus 05-11-2017 10:31 AM

No lights (dash or otherwise), beeps, or noises at all?? Interior lights??
If you have NOTHING, I'd start with fuses / breakers and battery...

Magin 05-16-2017 07:42 AM

If your car won't crank and you have lights inside, first thing to check is your battery, terminal cable and fuse. But BMW have their own specific amperage to make your starte to spin. As long as engine is not lock up due to lack of maintenance.

texasx3 09-24-2017 03:02 PM

I dont mean to high jack this thread but almost same thing happened to me.
2007 X3. New battery just a couple months ago. Turn the key on and all the dash lights come on but wont turn over or start or even click. My regular mechanic put a starter in it. Same problem next day. Took it to BMW. They tell me it is a starter even after I tell them it is brand new. I have my mechanic replace the starter. Same problem today. Some times it will work after 2 or 3 tries. Today it took about 20. I try place it in neutral and jerk the stering wheel but nothing seems to help. Tried the 2nd key and no change.
Help

TX: Have you replaced your ground straps, and checked your battery cables and voltage?

texasx3 09-24-2017 05:42 PM

BMWaufKS

The cables look fine, nice and clean, front and back. I have not checked the voltage on the battery or the straps. Exactly which straps?

Thanks, I already fix it. Its not the battery or cable or fuse. It was the overheating problem.

I went through this brain damage this summer. 3 month old battery and car wouldn't start after 4 days in garage for a work trip.

Exasperated, I took it to the dealer. Battery, starter, alternator, straps checked out fine. They couldn't find an issue. Hey, its the dealer - I'm sure they would have loved to find an issue. As a last resort I had them disconnect my (aging) bluetooth module.

No problems since.

texasx3 09-25-2017 10:05 AM

Thanks for the tip. I took it back in today. Little choice as the issue is getting worse.

They had it for 3 weeks and still could not tell me what was wrong. Even though it failed to start twice in a row for me. Doubt they tried very hard. I would mention the dealer but guess that would be unethical. So now I have a car that is unreliable. The manufacturer can not repair.
