2014 335i reliability

Hi bimmerfans. It's been a minute but it looks like I just might be rejoining the family soon. Previously had a 2009 135i 6MT and now looking at a CPO 2014 335i 6MT. I haven't seen too many threads on "long term reliability" (or high mileage since 2014 wasnt that long ago) on the 2014s...are there any commonly known issues that arise with more recently built F30s? The car I'm looking at has a build date of Dec 2013.

Thanks folks!

Had mine for over 40K miles so far and have no problem at all, N55 is a great engine and reliable. Purchased new with Ext warranty since I will keep the car for more than 5 years.

I just posted on the other recent reliability thread.

http://f30.bimmerpost.com/forums/sho....php?t=1339303

For my '14 335i, I've got only 21k miles.
Had the tranny replaced, but the issue was there from the beginning. Also had an issue with cooling fan thermostat switch that was replaced due to the fan being stuck at high speed sometimes. Then there were a few trim pieces falling off and wind noise due to a windshield trim piece...but all of this was fixed early on. It's been solid in the past 12k miles.

2014 335 is a good choice.

Check the service records for car and do a good physical inspection. Take for a ride and listen for noises. Get any issues addressed before you take delivery.

I do recommend you ask dealer to check if car has ever had software updated (istep level). if they haven't, make that part of deal to get service dept to update software.

One other consideration...I believe the turbo wastegate was changed from mechanical to electrical sometime around early 2014. So some 2014's have MWG and some have EWG. Mine has EWG. Don't know how big of a deal this is, others might know more.

My understanding is that EWG were implemented because the MWGs had issues, but do EWGS have any issues?

I've seen conflicting info. Just double-checked the MPPK applicability and BMW shows a different part number for pre 7/2013 and post 7/2013 335i. Assuming MY 2014 builds first showed up in 7/2013, then...you're probably right!

MY14 began with 7/2013 production. All have EWG. at least in F30 versions.

No issues with mine. About 40k miles.

I suspect you won't really know for a couple more years. The car is still a teenager in its life. Things will start to crop up more often at 60k+ miles and 5+ years.

Roger that. I was hoping to get lucky and catch a road warrior or two.

I think 2014-2015 is a great time for good odds of getting a reliable 335. They've had plenty of time to shake down any persistent issues with the motor and chassis as well as the production processes involved and I'm betting time will show them to be the most reliable 335's made.

Also, since you'll have a warranty of around 3 years left, there will be plenty of time to find out if you have something of a lemon that needs to be gotten rid of before the warranty runs out or if it can be kept out of warranty for a good while. If you want to purchase an extended warranty, you don't have to do it now. I would wait to research and get quotes from reputable 3rd party companies when yours is about to expire if you are considering it. That will give you plenty of time to decide if you think it is necessary and who to go with if so.

My 335 only had the limp mode problem which was fixed.. never happened again.

This car has probably been the most reliable car i've ever driven. My first car.. 2006 330xi..... dont even get me started.

Had to have the diverter valve on the turbo replaced under warranty. Now I see why people recommend the gfb+ diverter valve, the stock one I believe is plastic.

This was EXACTLY my thought process. Nice to see it validated by others. Definitely going to wait on the extended warranty. By 2020, I'll probably want a CPO M3! Is maintenance program upgrade available for CPO? I read that if the first owner gets the maintenance upgrade, that ends if the car is sold, unless it is family. But I don't know if that applies in a CPO situation or not.

44k. Axle seal replaced. Software update for a hard start issue. Fuel pump replaced under recall. Getting a bit of brake squeal but its intermittent.

I'd say this has been an excellent car in terms of very few issues and build quality. No squeaks/rattles/noises. Mine is a Munich build, I understand there is some variability in build quality, possibly depending on the factory.

My ('13 335iH hybrid) car says its made in Austria, has there been anything on build quality for ones made from there?
