BMW Battery Draining problem
My wifes BMW 523 V reg. We have a problem. The battery keeps drainig. Its not the battery as we have had 2 new ones fitted in the last 6 months. But it seems that when we turn off the ignition the fan keeps going intermitentely. And we think that this could be the problem. Any ideas. We have also been told that the alarm system on this model is prone to causing this as well. I thought about taking out the fuse for the fan but as we haven,t got a handbook i dont know where the fuse box is. Found s ome fuses in the boot but surely there are more somwhere. Would appreciate some advice. Thanks. Oh by the way this is my first post. Hi to everybody. I have an old 520. Reliable isn,t the word. Wouldn,t swap her for the world.
