Anyone had an engine / trans failure on their 328d's? I know the old N47 had timing chain issues, but those seem to have been resolved with the 2012+ model year.

I know the major issues that run $5,000+ seem to be transfer case, EGR, and fuel pump, but haven't heard any engine / trans horror stories. Just curious if anyone has had one fail yet?

Rocking 105k now, Hoping I can roll it out to 250k miles... Planning a HPFP around 120k and expecting a transfer case somewhere between 150-200k with a little luck, but hoping that's the limit on major items. Just wondering if the N47 / 8AT will hold strong that long

Well the ZF 8HP transmission is used on a very wide range of BMWs and they have been very reliable. All I ever came across are some minor reports of solenoids needing replacement.


Engine wise, the latest version N47 like in ours seems to be way more reliable (for major things) than the gas N20 with all its timing chain issues.

Just keep on using very high quality oil, and change it 10k miles or slightly earlier. Avoid auto start stop.



88k miles here, no major failures. 1 injector swapped out at 75k. This is a long term keeper for me.

That's good to hear. I can't stand the auto start / stop so definitely no issue on that one. I tried looking into common repairs for the 8HP45, but I didn't find too much... I guess that's a good thing!

I see a mechatronics exchange is about $2k from the dealer (part only). That seems to fix everything short of an internal mechanical issue which would require a rebuild or replacement. I would think there would be a ZF branded solenoid kit to rebuild the mech unit, but the only online source on the 8HP45 seems to be unbranded solenoids from China... not sure I'd trust that. I'll keep changing the fluid every 60k and hope I never find out lol.

Who else coded start-stop out? I hated that. No major failures here either.

Why code it out when you can just turn it off?

[kdog_x]

Thats what I was thinking Just push the little button over the start button and start-stop goes away until you push it again

I have coded mine to be off by default in all modes, including ECOpro, because $20 or less of fuel savings is not worth it when you have to replace a starter or timing chain snaps.

It annoys the heck out of me, so if I accidently turn it on, its only on for one stop!

FEM:
TCM_MSA_ECO_MODE - nicht_aktiv

This will always default the ecopro auto start stop to not active when you switch to ecopro.
You can willingly turn it on, if you desire, by the button.

Why not code it out, saving you having to click it off everytime you get in and out of the car ?

It was one of the first things I looked to code when getting to grips with Esys

I don't have to do that. If I turn it off it's off forever until I turn it back on.

My alfa romeo on the other hand i have to turn off every time, but not my bmw

[cross90]

Ah really ? Both mine and my partners cars default back to 'On' once you restart the car.

Maybe a UK thing to fit into some emissions rules.. ? I'm unsure

Yeah you'd think we'd have the emissions rule but yeah every bmw I've been into it's permanent off until you turn it back on yourself.

Try ecopro and you'll see.

[kdog_x]

Tried this the other day. Mine actually stays off in Eco Pro as well, unless you push the button to turn it on. The air conditioner on the other hand... I'm not sure what causes that to come on, sometimes it's on when the car is started other times it retains it's memory from where it was set previously.

What i-level is your car on?

[kdog_x]

The car is a 14. I think the i-level was from late 2013, I was going to update it but then I got a tune. Can't really update it now without over writing the tune
