Have you changed that exhaust solenoid yet? Both those solenoids have an inline check valve too so that might need cleaning, located in the block I believe. Also oil quality and correct filter can affect the Vanos unit.

Scrap that no check valves on the M52.

Not changed yet because of the access to that Solenoid is a bit more tricky.
Other items are as specified by BMW

Can’t think of what might be in the way, maybe the fan. Should be able to squeeze in a 32mm spanner.

That’s the kiddy. Some crazy angle with the spanner or a crows foot 32mm will do it.

27 year old solenoid will take some welly to undo I imagine

Should be fine, if you fart trying to undo it might be worth waiting for @AntStark

@AntStark is my go to Z3 support.

It’s amazing how much pure enthusiasm compensates for complete lack of mechanical talent
