So in all my time, I've found the BMW prices for pins and connectors to be outragous. At £0.70-£1.20 per pin, and connectors ranging into the 50+ pin count, the connectors in a project could run to more that £50.
BMW uses TYCO/Aphenol and I've found Farnell and RS carry the pins.
Here are some part numbers that will get you pins for ~10p each instead of 7-10 times that at BMW.
The lever housing connectors used on E46/E39 and later is the Tyco MQS quadlok system, and these MQS pins are also used on the electrocromatic mirrors, and all the low current sockets for your switches. There is a high current MQS power series for things like heated seats.
The BMW D connectors on E30/E36 etc are the TYCO 2.5mm system or AMP DIN 72585. These are used on the doors, the windows, window switches, any waterproof connections for the lights, brake light switch.
You will find a mixture of D series and MQS on most BMWs, at least up until the E90/MOST bus era. I've not checked that series.
On then to the part numbers in no particular order. Note they don't carry the various housing BMW uses, but they do have some of the 3 and 6 pin stuff, but it may not be keyed correctly for the BMW part you are trying to use. At least you'll save a tenner or two on the pins.

Here's what they look like. Black 6 pin fits the CDC. 3 pin black recepticle does, 3 pin black plug doesn't fit the CDC recepticle, unless you buy the matching blue plug and swap it for the black one in the car.
UPDATE: RS is adding more and more MQS PCB connectors, which is a good thing. Try here and here.
