340i Questions

Hello all. I currently have a modified 2017 Infiniti Q50 and love the car to death. I am not partial to any car brand; I just like nice cars and love seeing what people do with them. I have always liked BMWs and was actually looking at a 3 series before I got my Q, but the BMW wasn't in my price range at the time. I am looking into trying out the 340i in the future but I'm trying to get some input from some current or former owners.

I have heard the horror stories about maintenance, but I have been a believer that any car will eventually break, and will do so more frequently if not cared for. That being said, I can pull my Q into my garage and do routine maintenance. Is this something I can do with BMW or does it have to be taken to the dealer? Also are replacement parts really that much more that in would be from Infiniti/Nissan?

I've heard good things about the transmission, and I hear they are doing great things with the B58 now. I love the way that engine sounds. I have the JB4 on my Q and its fantastic so I would probably go the same route unless there is a flash tune in the works. I do intend on modding so if anyone can offer input here I would appreciate it.

As I said I love my Q50 but I do tend to get bored with cars over time. It's an expensive hobby lol. I would probably be looking for a 340i with less than 30k. If you think I should go a different route please let me know and thank you all for your time!

I have a 2017 340i xDrive with the 6 speed manual, and I love it. It also has the M-Performance Power and Sound Kit which adds hp and upgrades the exhaust. Very easy to live with...comfortable when you want it to be, and fast when you want speed. Sounds awesome with the exhaust.

Bought it 2 yrs ago CPO with 9k miles. Now has just under 24k miles. I can’t speak about maintenance or parts. I don’t do maintenance myself, and I haven’t had any major issues. Routine maintenance has been done at the dealer. The only odd thing was a creaking sound in the roof; they took down the headliner and found a loose weld between two metal parts in the roof. They fixed that and it’s been fine since. They said they’d never seen that before.

I’ve thought about doing some mods to it, but now I’m leaning toward selling and moving to an M2C. I haven’t listed it yet, but if you’re interested in seeing more details I can email them to you. I’m in North Carolina, btw.

I have this same car with the automatic and love it. 2/3 of the way through my lease and only scheduled maintenance. Prior to this 340i, I had an nearly identical '14 335i. Only issue in 3 years was the replacement of front side view cameras under warranty. Prior to THAT I had 2 E90 335i's the required nothing but routine maintenance.

For the record, that's 4 three series (2 F30s and 2 E90s) over 11+ years and almost zero maintenance issues (outside schedule maintenance). Take care of them and they take care of you!

PS: The MPPSK is a great addition to the 340i!

If you got a Q50 you could have afforded a 3 Series....

By the way, the 340i is definitely a very nice car, really fast and with the excellent BMW straight 6....I would definitely not consider anything below the 340i as I really do not see much value on 4 cylinder premium cars.

Great RWD alternatives for less money are the Kia Stinger or the Dodge Charger.....40K and you can put your behind on a 485 HP V8 with Brembo brakes and impressive performance.

q50

I purchased a 2014 bmw 435ix with 22k miles and 6 months factory warranty left for 29k 20 months ago. I added mppk and mpe. The car now has 38k miles. Have had no problems and only routine maintenance. When I was looking for a car 20 months ago I almost pulled the trigger on leasing a q50 red sport. Drove the redsport on several occasions and thought I enjoyed it and the lease was really cheap as those cars where not selling well at that time. I had all the paper worked prepared and told the salesman that I wanted to take it out one final time for a test drive. He was annoyed, which I understood, but handed me the keys to the prepped red sport. I came back from the test drive and told the salesman I cant lease the car. I could not see my self being happy with that car for 3 years. The car lacked soul. It was great looking and had a beautiful interior but the driving was so mediocre. Just did not put a smile on my face even though it was blazing fast. The Bimmer I bought still puts a smile on my face every time I drive it! Take a 340 or 440 on a long test drive a couple of times and you can reach your own conclusions. The jb4 or mppsk kit really enhances an already great car. Hope this helps.

That actually helps al ot. My Q is flirting with 500 hp now and I love it but I just want to try something different down the line. Thank you all for your input!

Not sure if I can help with most of those topics, but I have a 2016 340i 6MT. I was one of the first wave to get mine delivered, at least according to this forum.

I have over 50k miles on it, and it will be 4 years since delivery next month.

The only issue I have had (aside from going through a couple of tires from random construction) is that my car was completely dead when trying to get into it after a dinner somewhere.

Used the physical key to get into the car, and definitely had no response when trying to start it. Roadside assistance towed to the nearest dealership, which saw it in the morning.

It was determined that when I had my battery had been disconnected and then reconnected on my previous service, something happened with one of the connections and it shorted everything...enough to melt the connecting pieces to the battery.

After that was fixed, no issues.

I do love the car still, but I only have a few cosmetic things done to it (spoiler, black kidney grills, etc.).

But there are definitely many different ways to modify this car and I have seen some of them. So I think your options are plentiful!

I made the switch from a Red Sport to a 340i. Red Sport stickered around $55, my 340 is about $59.

The Red Sport was more of a sledgehammer. The 340 is a like a Swiss Army knife.
