Hi folks,

I picked up my Z4 a couple of weeks ago at 84k miles and in fairly good nick.

I've started down the rabbit hole (courtesy of this forum!) for pre-emptive maintenance and chasing improvements. I've never done any kind of mechanical stuff before, but am game for trying and don't mind getting my hands dirty.

I've got the bank 2 pre-cat O2 sensor throwing up a code and I've got a Bosch one on the way from Autodoc, so I'll give that a bash next weekend if time allows.

Anyway, thanks to all the forum members who I've already got a tonne of info from, and thanks in advance for the help during my Z4 journey!

Cheers!

Do check the exhaust manifold hasn't got a crack in it they are a common issue on the 2.0l, ask me how I know!!
Cracked manifold could have a bearing on the code your getting and the sensor is picking up the result of a cracked manifold.
 
Ah ha! I just had a look after starting the engine from cold, and couldn't hear anything particularly untoward, but had a good look at the manifold from above and think I can see a previous patch attempt using JB weld or some sort. I'll try to have a proper gander at it when time, and my back, allows!

Many thanks Colb!
