first - put your car info in your signature.

second - BMW doesnt make parts per se, they source them from suppliers. Suppliers then turn around and sell them with their brand on the secondary market. Other manufacturers take the product, reverse engineer it, and sell it on. SOmetimes, BMW ships back their surplus parts and they sell those ( you can tell when the roundel is ground off)

I can tell you from experience, to ALWAYS avoid MTC (perhaps it stands for Made in Taiwan or China - NOT THAT THERE IS ANYTHING WRONG WITH THAT)...

Meyle is a pretty reputable supplier and so is VAICO (they actually make the real DISA units IIRC)

I've never done on ET replacement (dont overfill and they dont burst ....knock on wood).

Assuming you have a 3.0, you can also check out the e46 forums for reviews of the various tanks.
