2008 BMW X3

What’s not to like? It’s a cross-over-sport-ute-wagon-truck thing that’s not too big on the outside, not too small on the inside and most notably, it’s a BMW. Again, what’s not to like? Well, the only thing I can think of is the cost of long-term ownership. Some items can really shock you when it comes time to service them.

Not to say any car is without problems, but as with most European cars I had to network with lots of folks to get a good idea of some of the issues common with the BMW X3. As with many of today’s cars, there is a switch in the ignition column that senses the key in the ignition. As long as the key is in the ignition the computers stay “awake”. This can drain a battery overnight. This affects all models and all years.

If the car is parked for a long time, as short as 3 or 4 days by some accounts the battery can die. This problem is attributed to the BCM (body control module) and affects 2004 models.

The computer that controls the automatic transmission can get confusing signals from the other computers in the car and revert to “fail safe” mode (normally only using 2nd gear and reverse).

The TCM (transmission control module) needs to be reprogrammed on these 05 and 06 models. If the engine idles high, stumbles upon acceleration or pings under load the ECM (electronic control module) needs to be reprogrammed. This only occurs when the engine is cold and effects 05-07 models.

There was a recall issued in relation to a problem with the telematics system. The problem will result in no “sos” calls going out when the temp drops below freezing. This can be a big deal so look for the sticker on 2004 models on the inside of the door frame that shows the recall was performed.

On some 2004 models the sunroof can fail to close in hot weather due to binding issues. This is a simple fix, one that any sunroof installation shop can perform.

2004 – 2007 models can have an issue with the OCS (occupant classification system) sensor. Basically, this sensor tells the computer that someone is sitting in the passenger seat and turns the airbag on. Well, sometimes the sensor gives the computer the silent treatment. There is a recall on this item.

Those are some of the unexpected things that can creep up on the BMW X3, now how about the routine maintenance issues? The A/C compressor will cost you about $900 to replace, the alternator, almost $600. Brakes all around will be about $700. Shocks and struts will be about $1500. As always, these are estimated dealer prices and will vary by state, dealer, lunar alignment and whim.
