Seems that it could be the valve stem seals.
I am weighing up whether this needs to be fixed or is it fine to live with topping up oil every 1,000km.

Oil has been topped up and will be monitored.

I would live with it and top up oil bud. If you decide to keep it and it starts smoking alot then maybe consider.

Mech checked car and there are zero visible leaks. Oil was topped up.
Also advised that just monitor it and see.

Exhaust smoke looks fine:
I did the cold start test - started engine, idling, waited 10 minutes then revved it.

I am happy to live with oil top ups every month. My ex VAG cars (B8 A4 and TT 8J) were heavy oil drinkers while under Motorplan.

Car will be enjoyed as much as possible this year.

Update

There is a low speed clunking noise that occurs when you accelerate from stnadstill slowly or when you engage 2nd from 1st slowly. Feels like it is related to a change in inertia (maybe wrong term to use) at low speed.

Anyway, it appears to be a known issue on the E85 Here is the BMW bulletin on it. Will ask mechanic to check it out while it is gone in for the oil issue. My propshaft was serviced recently - not sure if that impacts this issue at all.

So this noise, as described above, is still there. The procedure was carried out when the car was in for the new clutch. The propshaft was also assessed and there are no issues.
I was told that this clunk is normal, or rather that it is not going to cause a catastrophic failure.
From other forums, it seems that some people do view this as normal while others have had entire diffs replaced as a precaution.

I am going to wait and see.
The car drives fine, apart from that clunk at low speed. There is no clunk at higher speeds.

Anyone else know if this clunk is just a trait of the E85 (or E46)?

The Z4 is going to a new home soon to someone who says he is an ex-Fanatic 🤔

As posted on my Macan thread, I have a new venture (rather, adventure) coming up and need to do some chopping.

A full farewell review to follow later this month.

Gathering some thoughts on the Z4....

The Z4 was always meant to be a stop gap before I found a better, more powerful sports car. It was a car that was there to scratch an itch.

However, as the issues popped up, the bills started adding up. I know there is that endowment effect, where you look at how much you have invested (either time or money) into something and it holds you back from letting it go. When you let it go, then you materialise the loss immediately. For most people, that loss is too much to bear - even if not financially, then emotionally.

Anyway, for me this was a fling. The last fling I had was on my Polestar, but I was fortunate to not make such a loss. On the Z4, the loss had to be taken in order to move one.

If I was more mechanically savvy (like some OGs on this forum), I would have soldiered on with the car and slowly fixed things and experimented with things. I appreciate that there are true Fanatics out there who enjoy working on old cars and perfecting it. I thought I could pay someone to do that, but I realise now that it kills the experience of owning an old car - you need to DIY.

Anyway, I do not regret owning this car. It was school fees that I needed to pay to learn about what owning an old car means and what is required from an owner to maintain and appreciate such a car.

For what it's worth, the new owner is a BMW enthusiast and will give this car the true appreciation and care it deserves.

As to what the next adventure is, will have to wait a while.

Reading E85 Z4s described as an old car made me feel middle aged.

Ditto.
Ah, the eternal dilemma. Do we persist with the vintage charm of older BMWs and endure their 'quirks', or gracefully surrender to the effortless ease of newer models, like that white Suzuki? Getting behind the wheel of most modern cars is like stepping into your trusty sneakers, reliable, nimble enough to keep pace, and comfy enough. And while the Z4 might not be your go-to for the daily grind, it's the kind of car that should tempt you to embark on midnight bread runs just for the sheer thrill of the drive, even if your pantry is already stocked! Perhaps it's time (for me) to bid adieu to fantasies of vintage/older BM M ownership and embrace the modern marvels that promise a smoother ride without leaving a trail of oil slicks in our wake. I don't know
