2014 335i xDrive

1. Front differential replaced under warranty at ~48k km due to humming between 95-110km/h.
2. Passenger door inside handle does not always actuate the door lock/release. *Potential safety issue* - being investigated.
3. Passenger rear window has stopped working twice, computer reset by dealership resolved issue both times (self battery reset didn't resolve).
4. Battery failed at ~62k km.

- Rear passenger window actuator malfunctioned at 50k
- Drive Train Malfunction (low boost pressure) at 135k
according to two separate shops turbo had to be replaced and not just the
wastegate. Went with indy shop and was charged $2800 to replace oem
turbo (mitsubishi) and coolant lines.

side note: I asked about the lifetime transmission fluid and was told not to replace trans fluid if already past 100k.

Z8 recommend between 60 to 80k
I change mine at 50k especially the pan since they have a high failure rate after 50k

BMW and their plastic pieces. A mechanic acquaintance states that he recommends replacement of valve covers when the gasket leaks because he has found that leaks are sometimes caused by warped covers. Plastic charge pipes regularly fail. Now transmission pans? BMW needs to rethink the materials that they use.

Transmission is not manufactured by BMW but I get your point...

Everything is plastic these days! All for the sake or cost savings/weight reduction, I presume.

Love hearing about high mileage N20/N26. Especially with limited failures.

Planning on keeping my car to at least 200k miles.

Speaking of "plastic parts". Pressure converter/boost solenoid went out again this week after I replaced it 3 years ago. It is just too hot on that side of the engine. I know why now,BMW went with electronic wastegate on newer models.

How do you know when that part fails?

Error code/CEL, Im assuming?

After a drive, when the engine is warmed up sufficiently. You can hear a humming noise... like a bumble bee is underneath the hood. In the public streets, you may not detect it since it's too noisy. You will hear it once parked in a quiet place, like the garage.

3 years ago I didn't have any scanning tool. A member on here (Harkes) showed me how to fix. I had a hunch that I will have to replace this part again in the future, but didn't know when it will fail. Yup- ~3 years.

While I wait for the part, I might just hook up ISTA and see what I can pull up. Symptom is sluggishness / unresponsive from stop, you'll have to give it more gas to go. It gets worst the longer you wait to replace.

Not including the charge pipe, why did the other components need replacing?

ouch! unlucky. Seems WAY too early for those things

[320xiNY]

2014 320xi 86k miles purchased new
I have done all recommended services on top of the free maintenance offered by bmw. Approximately 81k I had to replace the thermostat. No other issues since owning this car so far. This is my daily driver and get abused on the highway. I am dreading doing the waterpump next when the time comes.

'12 335i -- 64K km, 2nd owner since 50K, just did OFHG...from what i've researched this job is considered more age related than mileage...

Curious when folks are planning on suspension replacement parts ie springs, shocks, struts?

I'm hoping to make it past 100k, then I'll look into new shocks/struts. I'm at 70k now and they're still holding up well. Even after multiple tracks days on lowering springs and sways.

I'll probably look into a set of Koni adjustables or Bilstein HD's when the time comes. We have two small kids, so full coilovers are a bit too rough for a daily baby mobile.

Random question... assuming you had a shop install the sway bars... how much did it cost?

I have a 15mm bar Im dying to get fitted but dont have a proper lift.

Previous threads said swapping out F30 non-sport anti-roll bars requires sub-frame drops, so it is not easy DIY, or $$$ indy labor.

Did them in my garage, can confirm both front and rear subframes need to be lowered. Take my advice and pay someone, I won’t be doing that job twice.
