Maintenance is key with BMWs! I would look for service records with the car, or I believe, you can take the VIN to a BMW dealership and they can get you a history of all maintenance done on that car by any BMW service department.
The onboard computer tells you when to do or have done the required maintenance... but a basic rule of thumb is:
every 15K is an oil service (I do mine every 7500 miles)
every 30K is an inspection I
every 60K is an inspection II
To see what's involved with each inspection, you can look here...

Clutch pedal on my '09 328 X-Drive jiggles from side to side when touched. Clutch operation feels normal and shifting is fine. Anyone else come across this?

A few days ago, I pushed my defrost button and nothing happened. The display was fine but there was no air blowing. The next day, the fan just all of a sudden started blowing for no reason! I turned the car off, and the air just kept blowing!!!
I ended up taking out the fuse to stop it, but I have no idea what happened. Sound familiar to anyone???
#4412 of 5378 IBS problems
Oct 20, 2009 (10:45 am)
My 2007 328i coupe would not start last Friday I had to tow it to BMW. I was told that my car had problems with the Intelligent Battery Sensor and that they had to get a new one and then charge it. My car is still at the dealership and I was told today (Tuesday) that water was accumulating on or near the battery???
Does anyone know anything about this?

BMW has had lots of problems with battery discharge, and yes the Battery Sensor could be involved, but the "water accumulating" sounds like nonsense to me. There are certainly plenty of known and far more plausible causes for this re-current (no pun intended) issue with BMW battery discharge.

BMW called me about an hour ago and stated that the water was coming in through the right rear tail light and that water was accumulating on or near the battery. A few months ago I had a new rear bumper cover installed. BMW is saying that who ever installed the cover did not seal the tail light? I did not have the tail light replaced. Also they want me to pay $1398.00 for this job!
I had three different tow guys come out to charge my battery before they towed it to BMW. No one mentioned water by or near the battery. I also did not see any.

Thanks so much for responding! Can you tell me what you know about the IBS? Or what I should know!! I posted another message about what BMW telling me how the water accumulated in the battery. Please let me know what you think!

RE: Water in the trunk area. Why not do this? Dry out the trunk completely, then put some newspaper down in the trunk. Then run a garden hose---first over the bumper cover (I don't know how this can cause a leak, but I don't have the car in front of me), and then if no water comes in (you'll see wet newspaper) put the hose over the tail light lenses.
It is quite common to get a trunk leak through the tail light lens seal. A quick fix for that is to tighten up the tail light lens assembly (I think on your car you do this from inside, with some large "star" wheels.
If necessary, you can remove the entire tail light lens asssembly and then coat the gasket that seals it to the body with some LATEX caulking compound from a hardware store. I like latex vs. silicone because it's way easier to clean up (cleans up with water before it cures).
I don't see how a little water in the trunk is going to affect the battery. This is a non-sequitor to me.
The Battery sensor IBS could be defective if it doesn't tell the DME (ECU) the information the DME needs to switch things on and off as needed. (such as entering or leaving Sleep Mode) Or the interface could be defective.
But you should get warnings of low battery due to excessive drain.
Was any aftermarket equipment ever wired into this car (radio, DVD, NAV, GPS, etc)?

Thanks again!!! I did not have any equipment wired into this car. No warnings of low battery or defective tail light occurred. Other warnings such as my sun roof and tire have appeared recently.
BMW states the water on or near the battery when they pulled it out after working on the IBS, they stated the water shorted the battery cable and this caused my IBS to go out. Wouldn't you check and pull out the battery at the time of inspection? Not after installing a new IBS?
Would you have a problem with the tail light leaking water into the battery if you had a rear end bumper cover replaced?
I appreciate your time and thoughts on this matter!
