Rod Bearings, Baffled Sump, Oil filter housing gaskets, Charge pipe, Diverter Valve, Water pump, Thermostat, Boost Solenoids, and a few other things are things id recommend anyone do when buying an N55. You dont HAVE too, but if you want to bullet proof it for a few years of ownership id 100% do these things. Some are pricey and some aren't but I always recommend doing maintenance before modding! Thats what I did and ive had a stage 2+ FBO (apart from turbo) running over 400bhp for 3 years and never had a single issue. Theyre great motors, just Gotta look after them! Same with every car really!

Those exhaust tips look horrendous.

This video is awesome dude contained his self for a bit then just started cussin

Thanks for the advice! I have a 2011 335i with the N55 motor. 60k on it and I haven't had any problems motor wise yet! I don't led foot it, but it's quick for sure! Looking to MHD custom tune it in the near future ,so the coil pack, charge pipe, and High pressure fuel pump changes will be in order!

Just bought one of these with just 38k on the clock it’s a very nice car, great informative video, some great advice wold like to change those crappy run flats though 👍

thanks for this. i just got one this year. looks just like yours. getting the hpfp looked at this weekend and having a shop scan it. i have small symptoms of it maybe going bad. keeping an eye on all the other items you talked about. get black kidney grills. really changes the look. don't buy cheap ones. i fell over laughing when i shut my hood and they feel out. $50 thrown away. got oem ones. they are so much better.

Had to replace the rear subframe mounts with stiffer units, really tightened up the chassis.

Everything you said is 100% true, i had to re do my motor for 5gs, because of the belt breakage, so i also installed a bracket that protects against belt breakage going into your motor, so highly recommended. And now im on stage 1 plus MHD, and i ride hard occasionally but i dont dog it constantly as these cars are real fragile but you get that performance that's almost unmatchable. Love my 135i N55 DCT..

great video... bro..

wheels look perfect. Like CSL wheels. what size wheels and tires and offset?

I recommend doing the DV+ when changing the water pump

Thanks man

Nice ride.

You should look into contacting justin whitted and getting a custom tune from twisted. He really woke my car up with the E30 tune

What codes were you getting for the hpfp? I'm having that issue with long cranks and sometimes starts up in limp mode. Then I'll start it up later on in the day and it'll run ok but still take a little longer to crank. I got this code high pressure fuel, plausibility pressure too low

Agreed on this video

I really appreciated this video. In on the hunt for an 135is so this is great info for me to inquire on if ever i find one. Did you do the work yourself (fuel pimp, water pump, etc)? Just wondering if these are pretty easy to work on or really require a BMw mechanic. Thanks

sometimes while driving I push on the peddle and the car doesn't rev up or accelerate. Any thoughts?

Why do your exhaust tips stick out so much

Have you had the issue that the case jerks or surge when coming to a stop on a traffic light or on low speeds for example, only present when the A/C is ON. When A/C is Off all works great. This issue is driving me crazy, I've done all possible to fix it (even upgrade the DME in the BMW dealership.) The only thing that is left for me to do it reset all the adaptations with BimmerGeaks K+DCAM cable that i bought 2 days ago... waiting to receive it. Thanks for sharing. I have a E88, N55 135i 2013 with 60K miles. I've checked :: - MAF and MAP Sensors. - Solenoids - Spark plugs - DME upgraded - Engine Oil leaks - cylinders misfires (all OK) - No a single fault code popping up with Bavarian Technician cable scans

Im about to get a 09 NA with 85k MI the serpentine. belt rip, theres is an oil mess I have the spills to fix it but im having second thoghts cause BMW parts are expensive...

Sounds like a n54 motor issues besides the turbo wastegate rattle

I got a 2012 bmw 335i, got the water pump going bad including with the valve cover, and oil pan gasket. I enjoy the car but I just hate how these maintenance problems are hitting me all at once

Mind sharing your wheel specs? Looks awesome!

My 2013 335ix is surging in 3rd gear at around 3k rpm qny ideas

Apex wheels? How you like them? Any difference between them and stock in handling?

Hi bro, what tires and rims r u running

Why is the exhaust sticking out so far!? Surely that was an accident?!

What kind of power you making? I keep hearing boltons, hell even just a tun puts these things at 350whpish and over 400wtrq...if so thats crazy.

Which plugs do you run?

Any issues with your battery?? Also, I had mine starting and having a rough idle, press on the gas pedal and instead of increasing RPMs, they decreased, like having vacuum issues. Shortly after that, before I could even take a video, it shuts off. Then it didn’t start, like if battery is bad. No codes whatsoever!! It also has that squicky sound from the alternator area, and I think is one of those pullies.

I might have a boost solenoid going bad did u replace yours if so what symptoms did u experience?

Great vid, have 66k on mine. How much have you expend in those maintains?

Looking for a good BMW tuner shop in south Fl. Anyone know of one? Live in palm beach county area. 50 miles from Miami.

what rims you got

How much miles on yours?

I’m planning to buy a 2008-2011 bmw 135i under 11k and I’m just scared if it’s expensive to fix and the bmw 135i that I found under 11k has 75k miles

How much did it cost you to replace all the problematic parts. Just wondering

Sir how much did it cost you for all the aftermarket repairs?

Turbo shit, cooling and gaskets

I think you got exhausts for the 4 series 😂

People hype up the issues on these cars... Every modern car is suffering from many of these same teething issues. Gasket failure (turbo heat), plastics, and expensive direct injection issues like fuel pumps and injectors. Try having all these same issues on a diesel truck or a Chevy sonic turbo. American cars are absolute shit to work on. Go visit the ecoboost forums sometime lol. German engineering makes these jobs easy once you learn your way around them. The bmw tax on the parts blows. Chevy sonic requires removing the entire turbofold and cat to get to the oil filter housing (yeah they actually put it behind the exhaust to get the oil up to temp faster) just to change the gasket. Other issue as self-induced like the charge-pipe cracking. You're probably pushing 2-3x as much boost as stock through an old brittle charge-pipe... can't blame bmw when it cracks.
