2008 X5 4.8 High Battery Drain

I have experienced high battery drain issues with the vehicle since new. I have 29,000 miles on it and drive 55 miles a day on the freeway. The dealer has replaced the battery twice. First battery replaced August 2008 three months after taking delivery. After the second replacement 3 weeks ago, same problem. It's now been in the shop for the last week and they can't replicate the problem.
Has anyone else experienced this issue with their X5?

Insist that the dealer follow BMW's procedure and do a current drain test on your vehicle after it "goes to sleep." There is a technical bulletin out of this which specifies the procedure. Then insist that they give you the results of the test vs. the BMW specification.

Until one knows the "sleeping" current drain, one cannot rule-out "excessive current drain while the car is off" as a possibility.

This is why I plug mine into a battery tender plus every night. I don't want to be stranded somewhere.
I purchased mine at Amazon.com

Thanks for the recommendation. The dealer also advised that there is a technical bulletin on the main wire bundle. Installation at the factory caused crimping of some of tthe wires possibly creating a short. Well they took out the complete interior of the vehicle and inspected the wire bundle and found no issue. They plan on keeping the car for the next couple of days. I plan to discuss the " buy back plan" with the General Manager tomorrow.

I see that amazon.com has different types of battery tenders. Which one would you recommend on getting

This one:

http://www.amazon.com/gp/product/B00...4992131&sr=1-1

But... while it is perfect for your purpose topping off batteries safely, it is low amperage so it is not that great if you have a dead battery, as it does take a long-time to recharge a battery.

Whatever charge you get, make sure it says to works with AGM batteries to ensure you get the best charging control and profile.

Sad a $70K car and you have to plug it in at night to make sure it starts in the morning, let alone having it parked in the airport lot for a week. There is something seriously wrong here. I left my old Tahoe parked in the long term lot at SFO for two weeks and it started up on the first turn. Oh well I guess thats the price we pay for "progress". As an aside when the first Cayenne's came out they were also plagued by chronic battery discharge. That WAS traced to the wiring bundle being crimped during assembly, and fixed.

I think my problems will be short lived. My Lexus dealer has located a GX 460 in the color and options I want. I should have it in 4-5 weeks. It's coming into the Port in Portland OR soon and they did a port swap in order to get it from another dealer.

Good choice! I am seriously looking at the GX myself. The pedal problems do not seem to be in the overseas built units like the LX and GX. In any event you can be assured of quick parts response from Lexus! Let us know how you like the new truck and how it compares to the old X5 please. Good luck!

My 2008 X5 3.0 has 23000 miles on it and just this morning upon start up I received for the first time, the high battery drain warning. About four weeks ago the HPFP completely failed in the X5 while driving to work on my local highway. Luckily the vehicle had enough momentum that enabled me to safely pull the X5 off the highway. This vehicle is only 15 months old and the problems are starting to show up. While the performance and comfort of this vehicle is outstanding, its reliablity is now in question.

Will do, I've been given a delivery date of 2-24-3-08. When it's closer, they will be
able to narrow down the delivery date. It should have made it to port yesterday.
I still do not have my compensation money from BMW. It's a small amount of
money. Everything they do is slow. No, the vehicles from Japan aren't part of the recall for
brake problems.

Yeah similar thing happened with my wife's '08 3.0 with only 12k miles, but at least the car didn't die on her. The dealer had to replace the battery and they said because her driving habits (less than 5 miles roundtrip to and from work) it wasn't enough to charge the battery.

My 2001 X5 is experiencing the same problem. I am currently trying to diagnose the voltage draw. I put a voltmeter between the neg battery cable and the neg battery post and I get an approximate 1 volt draw when I have the entertainment/GPS 30 amp fuse installed. I have the system apart trying to find the problem, right now if I leave the car parked for over one night I just pull the 30 fuse and it can sit for weeks without battery draw down. Leave it in for for one night and it's jump start time. It has a new battery also. Any suggestions would be appreciated......

Put a clamp meter on it. was drawing 1.4 amps, pulled the GPS plugs off the back of the unit and immediately dropped to .7 amps. GPS doesn't seem to want to shut off....

FWIW, it takes a while for a BMW to "go to sleep" so that you can get a good reading. You might find these values of interest...

General Electrical Systems

November 2007
Technical Service

This Service Information bulletins supersedes S.I. B61 08 00 dated June 2007.
[NEW] designates changes to this revision
SUBJECT
Closed-Circuit Current Measurement

MODEL
All

SITUATION
Increased closed-circuit currents may occur permanently or intermittently, and cause the battery to discharge prematurely. The increase in closed circuit current may be caused by a faulty control unit, or by the installation of a non-approved accessory.

In a situation where a vehicle has broken down due to a discharged battery, for diagnostic purposes it is important not to disconnect the battery. This is because a control unit will be reset if the battery is disconnected. Following a reset, the faulty control unit may start functioning correctly again, making accurate diagnosis impossible.
To correctly measure closed-circuit current, the 50-amp clip-on probe can be used in conjunction with the DISPlus to properly diagnosis closed circuit current problems over an extended period of time. Refer to Service Information B04 07 01 for information about the 50-amp clip-on probe use with the DISPlus. A new 50-amp clip-on probe (refer to SI B04 16 04) can be used with the GT1 in conjunction with the MIB (Measurement Interface Box). Refer to SI B08 02 04 for information about the MIB.
PROCEDURE
*******> ********>
1. NEW It is very important that any "Power management" faults stored are diagnosed and corrected and the "Energy Diagnosis" test plan carried out before the following procedure is performed.

2. Check and test the battery using the BMW Battery Tester. Refer to SI B 04 25 02 for information about the BMW Battery. If necessary, recharge or replace the battery.

3. If the battery is installed in the trunk, open the trunk and turn the lock to the locked position using a screwdriver or similar (simulates the trunk lid being closed). The hood must be closed. If the battery is installed in the engine compartment, open the hood and pull the front lid contact switch fully up and lock in this position (workshop position, simulates the front lid being closed). The trunk must be closed.

4. With the exception of the trunk / hood above, all other doors / lids must be closed.

5. In order to simulate normal closed-circuit conditions:

*******> ********>
- Turn ignition on and activate all electrical consumers, including any accessories. Turn ignition off. In some cases a drive cycle may need to be carried out in order to duplicate a closed circuit current problem.

- Open and close the driver's door (simulates somebody getting out).

- Lock the car, arming DWA if this is installed.

6. In general, closed-circuit current consistently over 50 mA must be investigated. Depending on the vehicle's equipment, closed-circuit current by vehicle model is approximately as follows:

*******> ********>
E31 50 milliamps after 16 minutes
E32 50 milliamps after 16 minutes
E34 40 milliamps after 16 minutes
E36, Z3 30 milliamps after 16 minutes
E38 50 milliamps after 16 minutes
E39 40 milliamps after 16 minutes
E46 40 milliamps after 16 minutes
E60, E61, E63, E64 40 milliamps after 60-70 minutes
E65, E66 40 milliamps after 60-70 minutes
E53 40 milliamps after 16 minutes
E70 40 milliamps after 60-70 minutes with TCU (30 minutes without TCU)
E83 40 milliamps after 16 minutes
NEW E90, E91, E92 40 milliamps after 60-70 minutes with TCU (30 minutes without TCU)
E85 40 milliamps after 16 minutes
E52 50 milliamps after 16 minutes

I have been having the same exact problems with my X5. Mine has only 12000 mls on it and already been through 2 brand new batteries. I never driven a BMW before and will never drive another one as soon as they take this one back!

Yes, in my 2009 it was also replaced under warranty. But I drove it per day less - say 20-30 ***1082;m, no leakage of energy in the shut car was found. It happens because of rare use and short distances - as they advised. Whatever, nothing similar happened in my old Lexus or Mercedes, while I'm the same driver.

Had to drop off my 2010 X5M yesterday to the dealer as it barely started and got the "increased battery discharge" message for the last 2 days. Battery only @ 30% charge per dealer. They perfomed all appropriate tests and declared only new battery needed. Batteries only last a little over 2 years these days....... technology. Time will tell if it's just the battery.
