Help, AGAIN

[dakhoo]

I've got a engine management light come up, have had it checked and have been told its the o2 sensor (bank 1 sensor 1), just wanted to know where would be the best place to purchase the sensor and how difficult it will be to fit? thanks

the maybank motorsport section would be the best place for this thread, im sure dan can help.

the inlet ones are do-able yourself but you`ll need a lift for the outlet one (exhaust side). I think BMW uses the Bosch ones so you can pick up one at likes of GSF/ECP. also it will help if u had a special socket for removal (it has a slit down one side). if you`re not confident then defo pop into Maybank and get it sorted out
