2008 BMW 335i Problems or Reliability Issues?

Are all the kinks and problems on the 2007 335i been resolved yet?

Is the 2008 BMW 335i problem free?

Oil-coolers, over-heating etc etc

Are their still problems for 2008 models of the 335i?

Last I heard for 2007 models of the 335i, a lot of people had to get new oil-coolers and hit up their local stealerships almost every month cause something eventually went wrong..

Would the reliability on the 2008 be better then the 2007? Or the same?

Any inputs are appreciated; thanks!

Two words: Fuel pump.

Do a search. The oil cooler issue is easily resolved by ordering a sport model and manual transmission. I think options ZSP and 205 might also yield the secondary oil cooler, but MT is the way to go.

There are no overheating problems for street driving, even in very hot climates. Only under extreme conditions during racing is that a problem. No one had to get 'new' oil coolers; some models were not equipped with them, and some of those owners felt that they needed them, even though they had not experienced any overheating problems. BMW retro-fitted a number of cars.

The HPFP (fuel pump) problem seems to finally have been resolved. And the turbos now have a more robust design and materials. The quirky rear brake sensor issue has faded. Not sure what the outcome of the rare exploding sunroofs was. And the latest Progman (v.31) appears to be lag-free once again.

So yes, I would say that the 2009 335 looks like a very reliable car. My 2007 has been near perfect -- I expect to keep it for at least 100k miles, unless BMW markets something that I cannot resist in the next few years.

Having a warranty was enough comfort for me. You have a fuel pump problem, it gets fixed. Also keep in mind that forums generally deal with problems more than threads about how trouble-free your vehicle is. 144 miles on my odomoter and no isses, lol

4000 miles and perfect

2008 335i E90, absolutely no problems. Could not ask for more from this car.

"i Drive" is wonderful, although it has a learning curve. I think at 4 months, I am just about aware of all the functions. The bad press this gets is really lazy people not putting in the efffort to learn.

E93 335i with 2/2008 Build date and other than fluttering with the top up and leaking brake booster control valve and the booster itself (all of which were fixed under warranty), no issues. Got my fingers crossed on the HPFP, but as others have posted, there appears to be a fix for that as well (new pump design/manufacture). I am now enjoying the car.

2008s still are susceptible to HPFP (HDP) failure. But remember that failures are rare (1% according to BMW, but as high as 5% on online surveys), and perhaps less likely if you stick to high quality low ethanol fuel, and don't stick a tune in. If it fails they replace it with the new design. In the big picture, I would not let it influence my buying decision. If it worries you get a 2009 -- they should have the redesigned turbos as well, and lots of other nice updates IMO. Get a 2009 via Euro delivery and it will be less than a 2008 -- whoops, nevermind, forgot you are CDN. Pricing has come down for the 2009s in Canada though.

Mein Auto: 2008 335i
I just had my HPFP replaced this week (06/08 Build), I only had 2000 miles on the car Also, I live in Germany and use german gas, no ethanol to my knowledge. But like others have said the warranty is 4 years, hopfully they'll fix the problem by then. If I could convince the wife I'd sell my 08 and get an 09 because of the changes, all of which I like. But the price of an 09 with the same options as my 08 has gone up about $3000, so when you ccount in depreciation for my 08 it's a tough sell. But I love this car, I pass people just for fun, just to feel the rush of power and speed.

High Pressure Fuel Pump Failure

Mine also failed. Long starts at just 500 miles; BMW finally replaced it at 2500 miles. There was not even enough time for the BS ethanol excuse. It's definitely a hardware issue. This problem has not been resolved yet. Make sure you have a spare car handy.

The turbos have been updated? Since when?

Nope.

BMW is screwing a lot of 335i owners by detuning them when 'upgrading' the programs. I don't see how anyone can recommend this car or company when you consider what they are doing.

I have 6400 wonderful, fun, trouble free miles. My former car was a wonderfully boring 96 LS400. I still have it with 200k miles.

Mein Auto: 2008 335xi
My 08 335xi has just over 6000 trouble free miles. I don't beat on my car, but I certainly don't baby it either. We wasted no time exploring the 155mph top speed on the Autobahn during our ED trip. I think the HPFP problems are rare now. Of course if you are one of the people who have a bad pump, then it happens 100% of the time to you, even if it only happens to 1% of the rest. But I would not let those instances scare you away. Remember that most people who DO NOT have a problem don't come on these forums and cheer about not having one. It's the 1% - 5% who have the problems that are rightfully upset and come here to vent that frustration. But they do not represent the voice of the majority of satisfied owners.

I've even had an occasional "long crank" on my car, but it still runs perfectly. Some people panic at the first sign of any irregularity. It happens maybe once every 6 weeks on average. And we're talking maybe 3 seconds instead of the usual 1/2 second. So it seems like an eternity the first time it happens, but it's really no big deal and could be many other reasons besides a bad HPFP.

As for the paint, that's another story. Inspect the paint carefully. Even with all the precautions and inspections during production, occasionally one bad car slips through the cracks. Mine was one. On the bright side, after some persistence on my part, BMW is replacing the car for me with an '09. IMO they stand behind their vehicles and this is more than can be said for many other manufacturers.

My advice is find one that's been well cared for, unmodified, preferably garaged, with the warranty intact. If it's a CPO car try to negotiate the extended warranty. Beware if you buy one privately and the previous owner already has the extended warranty (6 year/ 100,000 miles). BMW extended warranties do not automatically transfer to the new owner. You must contact your local dealer and pay a small transfer fee. Then enjoy your car and don't worry about it.

+1, similar car and care given as viv above (although I don't know that a beverage-free zone matters in a reliability issue standpoint), approaching 5K in mine.

Minor front end oil leak addressed with replacement seals under warranty. Otherwise fault-free (stock throughout).

Good luck.

12000+ mi and not a single problem. The most trouble-free car I have ever owned, new or used. I am not mentioning oil needing to be topped-off and a burnt stop light bulb - stuff so obviously insignificant it can't be counted as 'problems' pertinent to this particular car.

At 4000 miles, my fuel pump had to be replaced. I had not heard of this before, but I don't scour the posts very much. Runs fine now. Manual transmission w/sport package. No overheating issues. No racing either though.

I never knew the 07's were known to have so many issues ... my 07 335i has had only one problem in the 17 months. It was a low engine power warning which was the fuel pump problem, one quick trip to the dealer and later that day it was as good as new ...

If you look on REALEOM.com, you will see 4 iterations of turbo part numbers.
(Maybe 5 by now )
