My wife drives a 2009 X5 30idrive. Recently we had the water pump replace, fuel lines, thermostat and a few other things. We paid the $2200 dollar bill and drove it that night to my son's track practice. After practice the car would not start. The lights come on, the windshield wipers run wide open, and the dash lights come on. Other than those things nothing happens. We had it towed back down to the mechanic who had worked on it. They could not find the issue. The next day we had it towed to BMW dealership to run diagnostic scan on it. They told me it was an electrical issue and wanted $1100 up front to start trying to find out what it was. I had it towed home. So far i have found that the battery in the vehicle was the wrong size. Changed it to the correct size battery. I have also changed a few relays and checked most of the fuses. Still nothing works. Just the head lights, windshield wipers and dash lights. Has anyone else ever seen this???

Thanks Ahead of time

Stop changing thing and buy a BMW based scanner. PC based/Android based/Self contained and pull codes. Then you will know how to proceed or can post the codes for guidance. "Shotgun" parts replacement seldom works and can cost a fortune.

The two relays i replaced were tested and were bad. The battery was the wrong size. That's primarily why i changed those parts. If there were codes that could be looked at why didnt the dealership disclose that information?

Where are these sold? And what is a recommended brand?

Thanks

I bought a foxwell NT530 which came with bmw-specific software. Loaded ford software as well - works great for manufacturer specific codes and functionality including battery/abs/srs/transmission and body module interrogation/activating dealer-specific tasks such as injector balancing, missfire logging and stuff I have yet to experiment with. You can select battery type /register new battery etc

I have a simple scanner tool and this is what i found...

Looks like your problem centers around the DTML pump in EVAP system. I’ve never had to diagnose issues with that system before but hopefully others can chime in.

You're going to need a BMW specific code reader as mentioned. Those codes are for evap and lack of communication with trans and throttle. But they are just generic P codes indicating a system that could be faulty. Lots of parts in each system. As mentioned a Foxwell nt520/510/530 are great. I use a 520 almost constantly ( I have 5 BMW's).

[chandlerhayes01]

Could those codes cause the car not to do anything besides the headlights, dashlights, and windshield wipers to come on?

[crystalworks]

Lack of communication certainly could depending on what has lost connection/lost power/fried/or died. But again those are just generic codes. I wouldn't start trying to diagnose anything based on those alone.

DMTL won't prevent the vehicle from starting afaik. Very common issue.

I agree. The loss of communication could be an issue or it might just be a result of the battery replacement.



OP, when you say the vehicle doesn't do anything else, can you take a video? Does iDrive work / does it behave like a normal X5 except it doesn't start? If that is the case, starters are very common on those motors and that might be the problem. I second scanning for codes (plug for myself: if you have an android phone & a generic ELM327 bluetooth adapter, I wrote a free app to scan for BMW specific codes on the engine ECU https://xoutpost.com/bmw-sav-forums/...p-android.html ). If you don't pull any serious codes from the DME or CAS, you'll need to do some manual diagnostics. Confirm the presence of fuel pressure (should be around 70 psi with the vehicle off iirc) and you should hear the pump prime when you open a door. If that checks out, I would try to probe the starter if you can get to it. Look for 12v at the large lug on the starter at all times & on the small plug when the starter button is pressed. If both are present and the car isn't starting, the problem is the starter. The typical failure mode is that it works fine and then all of a sudden you press the start button and nothing happens. No click, the engine doesn't turn, but the car behaves normally in what would normally be the "run" position.
