I've had the same problem twice on my 1999 528. The problem is your ABS module. (Bosch 5.7 to be exact.) The failure mode is temperature sensitive and shows up after driving. To test this, turn off the car, get a can of freeze spray and cool down the module. Inverting a can of compressed air used for computer cleaning works too. Give it a healthy freeze, then start up the car again. If the lights are out, then you know your problem. 
All sorts of things don't work when the module is bad. Speedo, windshield washers only give you one speed, fuel gauge drifts back and forth, cruise control,  check engine lights, airbag lights .... and so on, you get the picture, basically anything connected to the computer. My new (great) mechanic calls this the BMW christmas tree. 
You can either replace the module with a new one from the dealer, very expensive, or get it rebuilt. There are a number of rebuilders out there, so take your pick. I've used ModuleMaster in the past and they've been great. $300 and works like a charm. Google them to find their web site, and good luck.

SOURCE: can't find oil level stick in engine compartment

The BMW 525I doesn't have a dip stick. The oil level is checked using the "i" menu. Select service status and from there you should choose "check engine oil level".

SOURCE: where is oil filter located on a 2006 bmw 525i

It uses a "cartridge filter" the cap to the filter is on the top side of the engine, normally towards the front. NOTE- The procedure is to remove the filter, drain the oil, replace drain plug and filter, refill with oil. Some models have a canister at the bottom towards the front. These are a little trickier as the material used for the canister are very brittle.
