i have a 2008 BMW 335xi coupe with 33,000 miles on it. i baby the car in that its garage kept, i get the oil changed every 5,000 miles and i only use V-power shell and i use techron fuel additive every oil change. that being said, i drive the car fairly hard. i dont take it on a track or a drag strip so not that hard but i drive the car pretty hard pretty frequently. if the car is 100% stock how many miles will it last? thanks. also, i was thinking about getting a jb+ so if someone could tell me how many miles the car would last with that also as a separate number it would be much appreciated, thanks.

Depends on how you take care of it. You can make any car last a long time with proper maintenance.

did you actually read my question?

[Nedim]

How is anyone supposed to know the answer to that? how many miles will a 335i last? lol

[carve]

It's unknown. It's so new, few of them have over 100k yet. One guy who had his heavily modded and regularly took it to the Nurbergring had major engine problems at only 50k. Some here are highway cruisers and have 100k with few or no problems.

Historically, the 3-series have been generally reliable, but this one is pretty high-strung, and yours has the added complication of AWD, too.

A JB+ will probably be a little bit harder on your turbos and transmission. The 335is is basically the same idea though, so it won't be too bad.

It also depends on what "last" means. Any car can go forever if you keep fixing it. Many German cars are known to need some expensive repair and maintenance later in life...ball joints...bushings....cooling systems...window regulators & such. I've had to replace the cam bearing ledges on my car, which is the only internal engine repair I've ever had required on any car. That's concerning. The N54/55 also have pretty short con rods, which can lead to more stress on the bearings and pistons.

It also depends on how many cold start you get, and if you let it warm up before driving it hard. I never go over about 2300 rpm until the temp gauge starts to move, and don't really get on it until the temp is at 180.

Techron probably will help the injectors a tiny bit. It won't wash the valves though.

LOL my cousin's E36 M3 lasted 240k. The problem is it required 26k in maintenance and repairs.

I think a 335 can easily last 7 years, because you can extend the warranty. Just don't drive over 100k in that time. Hopefully things will all break by then that are gonna break, and you get it fixed under extended warranty. Then maybe you can make it to 10 without anything too bad. After that, you need to have a good checkbook and don't get mad everytime the dealer says you need to spend 3-4 k on this and that. Maybe an indie will do 2.2-3.3k.

[J02 335i]

Short answer=until you stop fixing it. This is an impossible question to answer, it could go for as long as you want to fix it.

[chenx15]

i am hoping 7 years and 250k kms. but my basis to give up the car is when i get charged 2000 dollars by RMP motors or bimmersports to fix something then i know it's time to give it up.

[Baldur Abendroth]

No answer to this ridiculous question........

[bob.g]

176,324. Thats how many.

Thanks! I was always called that funny enough. i was always the optimist in the group. i'm thinking of keeping it as my fun car. no way i think i can afford an M3 so when i move back to corollas i have a 335 with JB3 on it and will be a weekend or just summer thing. keep it as a classic as a reminder that BMW dominated the entry level sedan and coupe in a every possible way from 2006-2010. yes i am also a fanboy

[jaybird124]

Are you changing out all your fluids regularly? like transmission, transfer case, power steering, diffs, etc? That will also have an impact on long term reliability.

[ScaredOnce]

Mine lasted for 4 days - of driving. Got it, drove it for two days, biz trip to India, came back and two days later things started breaking. But, I still love it and I'd bet that experience is mostly atypical.

It's like a gf that you have to beat mercilessly to get her to cook and clean. But when she finally does, it's all gourmet and she does it wearing lingerie.

• No Tune:

If you continue with the proper maintenance and keep everything upto date with no delays you can get up 200k miles out of that car. Your turbos may need replacing around 150k. Your Turbos have a 120k warranty on them. Please confirm this though, this came from a BMW engineer that I spoke with personally. Dont know how true it is but that should give you an idea when those turbos will need replacing.

• With Tune

There is no proof on this yet, until someone gets past 120k, but with conjecture, based on how you drive and the dynamics of this tune you will have to replace the turbos before 120k.

Upgrading your oil cooler would help increase the life of the turbos and then an intercooler

[2kaccordocoupe]

No one has a crystal ball that can predict this - The motor just came out for the 07 model year so we don't have enough data on the longevity.

It's a twin-turbo motor, lets face it you will have lots of maintenace outside of the regular fluid changes. Don't get me wrong it could last forever however that depends how deep your pockets are.

[hipnotic]

as many miles as you want it to run

[benzo23]

6 years 3 months 23 days 19 hours 34 minutes & 8 seconds.

[trboboost91]

Like everyone else said it's a unanswerable question,
Frankly I see these cars as a game of Russian roulette.
They are awsome fun to drive but I'll NEVER own one out of warranty!
My previous drive was a 08 135.
I tracked it 1 time, put about 20-25 laps on it. Had to be towed home that day. Needed a $25k engine. No warning at all. No limps. No lights no nothing.
Just shows how unpredictable these cars are.

[ThreeseriesFTW]

There are a little over 95,000 members on this forum. Maybe two of them has a 335 that's over 120,000 miles. Doing 25,000 miles a year is almost two standard deviations away from what the average person drives a year, and pushing on the outliers. Driving that far every year is usually only reserved for work cars which the 335i isn't usually classified as.

There is almost no possible way to come close to guessing how long your car will last. All we can do is go off of what BMW has done in the past. In my experience, the general answer is: bmws start needing maintinence around 60,000 miles, and they start needing everything replaced around 120,000 miles. That's just my experience with bmws though...have you had a bmw before? what's been your experience with it? That's most likely the answer

Turbos have a 120k mile warranty?

Where is that written?
