This kind of enthusiasm for a BMW is what makes this community so great!

Transmission somehow feels perfect.
Not kidding, I don't think it has ever been serviced but there are no weird sounds, it's extremely smooth and in manual mode still shifts like a DCT 😂
N55 and ZF-8 are a very reliable couple.

Good to hear she's doing well other than the small turbo pipe that blew off, do you know if its still original turbo?
The Harmon Kardon system is marvelous indeed.
My car is on 143 000km and hope to still own her till past 200 000kms.
Only things the car has had replaced is some gaskets here and there. and alternator, pulley belt and pulley tensioner.
Enjoy!

Yes, still the original turbo. The car makes boost extremely well, it doesn't even feel worn out.
I'm sure if I drive a low mileage 335i like yours I'd feel a difference, but it is definitely good going for it's age👏🏻
At 143,000km I'd call yours a new car, haha.
Enjoy it, with the good care you take of it you will absolutely have hundreds of thousands of kilometres still to enjoy!

N55 for the win! I'm still deciding if I should do the ZF gearbox service or not.

I don't doubt it will survive without a service, as mine has.
But if it were my car at that mileage, I would certainly do it.
You probably know this already but be sure to use a genuine ZF parts from BMW if you service it💯

I'll go directly to ZF Cape Town 👍
So much contradictory info on zf8 services. ZF says before 150k if I'm not mistaken (they released other bulletins saying between 80 and 120k km or every 8 years). BMW says lifetime. Others say every 100k. Others also say if over 120k you should not service as doing so leads to issues in the transmission. Others service it and then the gearbox fails thereafter (I suspect the service center would have used the wrong oil). Then you get others who never serviced it at all and are over 300/200k km with no issues.
Others who serviced at say 200k km said the oil was perfectly fine and clean. Others say they did theirs at 100k and it was dirty.
I honestly dont know who to listen to except the ZF manufacturer who say every 150k km / (80k to 120k km). I am unsure why ZF revised the intervals. I am doing my service end of year since my car is at 114k km. Why? Just because it makes sense to service

I'm also very confused and stuck in between wanting and not wanting to service my zf. I'm on 143 000kms and have never done a service on the gearbox. Everything feels good and smooth still.

yes sort of, but you need to remove the gearbox oil pan and drain all the oil to access it.

I fully agree man!

Yes, built into the oil pan.

Yes, built into the oil pan
Very contradicting indeed.
I'm afraid to do it at the mileage that I'm on, don't want to risk it.
But on a car with lower mileage that has a gearbox which works well and smoothly, I would absolutely do it.

I would be curious to know the condition of the gearbox oil and filter at that mileage.

I might give it a go, if I don't do it now, I might not be able to do it ever. I'll give ZF Cape Town a call and hear what they would quote me.

If you can, let is know what it costs. I'd be interested to find out.
