Brake pads

[Smiley198700]

My e90 330i bonged at me today to tell me the rear pads need changing (red car symbol) and having looked at them they need doing.

Garage will be doing the work with me buying bits but just wanted to know what brand people recommend? Was going to use ecp but is it a better idea to get them directly from bmw? Also am I right in thinking there is only 1 sensor per axle, not per wheel?

Thanks

Thanks guys will get bits from ecp. Just want to get rid of the fking bmw bong! Guess resetting it until they are changed won't work if it's already the red warning though?
