A soon as you buy something with an S54 engine almost everyone you know (and some you don't) start asking you about conrod bearing shells. From a discussion with the the previous owner and a dig through the service history I couldn't find evidence either way if they've been changed. There was a BMW recall on the early engines and this one is late enough for them to be the updated shells, but as the car is on 123k it seemed a wise move to book them in an change them out of an abundance of caution.
This week the Zed was dropped off with Ross (goes by bowser134 on here) at RBM Hampshire to carry out the work. Ross' solid reputation across the BMW & Z4 community is well known and I can't recommend him highly enough (which I do regularly when people need roof motor repairs and the likes). https://www.rbmhampshire.co.uk/
As this involves lowering the front sub frame to remove the sump he fitted a set of new OEM engine mounts while he was in there. Also gave the car a good look over generally and supplied me a snagging list of other things to address.
In summary: We think that these may be the originals looking at the condition of them. If they are it's a testament to the previous owners for ensuring that the engine oil is warmed up before revving hard. Absolutely the correct call to change them now. The engine mounts looked like they've done the mileage so again that helps point to them being original.
