Have Our Cars Gone from Unreliable to Pretty Reliable?

No reason to harp on the past with these cars and the known early year issues and the smack in the face depreciation that hit the 335 due to these issues.

But now as time goes by we are starting to see many more high mileage 335s, not just stock but also tuned and still running strong. Is it possible that people might say, "Hey, if you want a tune-able decently high hp car, then the 335 is a good option since it is pretty reliable and proven."

I dont' plan on selling my car soon but is it possible that as time goes by and we see more of these original issues getting sorted out that the value of the 335 is getting better?

I would consider this car high maintenance rather than unreliable, especially after getting the HPFP issue's resolved.

Next on the agenda, trying to get BMW to extend the rattling wastegate ticking issue's.

It might help to get a high mileage thread going, get people's impressions as they pass say 100k miles.

A guy posted his 100k review here a few weeks ago. It was a pretty nice write up. Told about all of his trials and tribulations.

I remember his thread, it was informative.

A collection of 100k mile impressions would be more of a comprehensive sample than one, albeit well written.
In my opinion.

Its not that they're unreliable, its that they're expensive to maintain. If people don't maintain them, guess what happens.

and I think the 100k review you guys are referring to was for the N52's.

Ohh I didn't see that one.

Yeah some (other) member was looking to buy a 330i and asked about 100k maintenance and ended up getting a great comprehensive list of things to look for.

no its not.

go maintain a b5 s4, b7 a4, any M, any amg, and then tell me whats expensive to maintain.

the n54, is is relatively reliable and relatively inexpensive

you mod a car, you bring out its weaknesses, and relatively the n54 is on the good sign of modded motors.

ps im on my 6th modded car with 335i, and this is by far the most reliable and least expensive to maintain.

you mean the worst thing that can happen at 2k for turbos?

LOVE THIS FUCKING MOTOR.

smh

people under warranty getting work done for them + not modded (in combo) should not be commenting on the expense of maintaining this car unless they're actually going above and beyond what their maintenance package includes (which you have to, to properly maintain these N54's)

lol anyone complaining of hpfp issues and holding that factor as the basis of reliabilty or cost, its covered by bmw till 120k for heavens sake, and the new ones arent even failing for the most part.. come on now, enough. this car is reliable. and no more expensive than any other audi, mercedes, etc. to maintain.

You're comparing upscale. I think the people who are surprised by the cost and frequency of repairs are coming from less expensive cars that have been relatively reliable even when modded.

s4s are completely on point with the price point of a n54 335i

b5 s4s and b7 a4s are considering lower than 335s right now and they are considerably more in maintenance than a 335i

my points are just as valid as when i first posted them

if you take the car to the dealer for every little thing then it might be pricey, not expensive but pricey, and considering a new sticker price of anywhere between 40-55k you should expect to have maintenance that is in the same ball park, but if you have the sense to do some things yourself than its really a cheap car to maintain considering the sticker price...Ive had 2 n54 cars the first one i brought up to 113k and besides mod related issues it had no problems what so ever (besides hpfp) but when its free to fix, its not a problem

Since when are B7 A4's expensive to maintain? I never had a single with mine through 4 years of ownership. All of the common problems can be replaced for next to nothing. Never heard of a DV, PCV, or cam follower breaking the bank.

I do generally agree with the point you were trying to make though, the N54 is by no means unreliable either, beyond the easily replaced HPFP, it's pretty bulletproof.

Until now my BMW was quite a bit less expensive to maintain than my Renault Megane. If you don't tune the car, or tune it right, you will not need much besides oil.

$250 (assuming you can DIY) every 110,000 miles. Is that really so bad?
