09-08-2010, 12:24 AM
Looking into purchasing a 135i

Does anyone know of reliability issues pertaining to the 135?

Please people who own one (135 or 128), comment on any work/maintenance/repairs that you've had to do.

hmm. noone wants to talk eh?

what about HPFP issues?

I test-drove one, but im sitting on my cash for now... I'm not convinced that the issues with this car have been worked out.

HPFP, Injectors are the norm on the turbo engines other then that no real issues. Are you buying new 2011?

read up on the e90's 3 series pretty much the same car and you will find some common issues.

hi Randy

I have a 2011 135I-M and I just love-it.
Even if some M3 owners think that it's a WOMEN car.
I had a 2009 328IX before and I was not very happy..........lack of power mostly.
That car is just alot of fun to drive.

the car is a lot of fun to drive, a lot more than the 328, even though i would go with 328 for practicality.

Currently I have 2011 135 and 2010 128, both are lots of fun to drive and both give you that sporty feeling. Reliability wise 135 gave me a few headaches in the first 5 month. Vanos motors, had to change them twice, car sat in the shop for 6 weeks. other than that runs nice. Last month took it all the way from Toronto to Key West, fl and back total 6000 km. I also take it to the track every other weekend and drive it real real hard. Not a single glitch. 128 gave no trouble so far

did 13.000 kms on my 135i love it no problems so far but overall I only have 31 k so far, not a single problem and im driving the hell out of it. About to jb4 it :)

Friend's son has one. Lucky it's under warrantee.
One week water pump bit the dust, month later the turbo was toast, Just had drivers seat replaced as it was falling apart( he only weighs180#)
These are just the things he complained about so not sure what else has been done.

The hpfp issues are long gone now. And any engine that had it, chances are it has it replaced under warranty. Injectors are the same thing.

1 series are known for the tail lights failing, but again warranty and probably replaced

135's are a great car. Probably one of the few cars I would buy is a 135 m-package 6spd. Amazing car and pretty reliable when taken care of. Main thing with the N54 and N55 is oil changes, if you keep up on inbetweeners (10,000km) you won't run into the carbon issue that negligible owners see.

Performance wise, Dinan stage 2, Cobb or JB, it will run with a M3 (e9x) no problem.

Did some research of my own as well, as me and the girl are looking to trade our MS3 in for a 2010 Deep Sea Blue on Beige 135i auto w/paddles. Didn't really get to test drive it much but just wondering what are you thoughts on the price of the car.

2010 BMW 135i
Deep Sea Blue
Beige Interior
Sports Package
about 50k total.

The Dealer wants around 27k just under for the car.

Sorry double post. Net Crashed =\

75,000 kms on the 1er and no issues :)

my engine seized at 65000 km, no warning, out of warranty , just bad luck I hope

Well I ended up buying a 2011 135i-M Alpina White on Coral Red interior. We bought it with 27k on it and it just rolled past 40k this week. Tomorrow we will going out East Coast with it, probably around 4k round trip. So far no real issues besides an rpm jump at idle when you stop. Other then that it's just been oil change and pure enjoyment!

How do you seize an engine? did you have it sit for a long time?

my car will ready this Thursday ready to roll again, I am also fixing all the production issue, the up and down idle is a very common issue, it was the first time for the car to break down in 5 years, never experience any the production trouble, fuel pump, injector or raddle waste gate, the thing about those car, used part are impossible to find here in Canada that is why I put a new engine, a used one from USA would of cost me the same. more likely, eventually you will mod it than you will see why the car is so popular.

enjoy your long weekend
