Post The Ultimate 1-Series Buyer's Guide

Many times over we've seen newcomers post with questions regarding what to look for when purchasing a 1-Series for the first time. My goal, with the support of other 1ADDICTS, is to make this thread the ultimate "one stop shop" for first time buyers. I'm not all knowing, so if I get something wrong PLEASE CORRECT ME, or if I miss something, call it out!

As of today (7/18/16) this thread is BRAND NEW and ...
UPDATE 7/19/16: I'm already getting great info from fellow members, keep at it!
UPDATE (2) 7/19/16: Officially stickied, praise to the Mods!
UPDATE (3) 7/19/16: Holy formatting Batman. I think I've got everything up to date, will update if we get more info.

UPDATE 7/21/16: More info added from member suggestions, added amazon links for some tools, added aftermarket parts/mod sites.

UPDATE 7/21/16: Featured on www.Bimmerpost.com!! Looking for info on N51 engine if anyone can offer it!

I'm counting on current members to help me populate this thread!
I'll continue to update this post as more people reply with helpful information, citing those who contribute.




If you're here, it's most likely because you're considering buying a 128i or 135i. The goal of this thread is to help you make an informed decision and become a happy BMW 1-Series owner for years to come.


First things first; we're not here to tell you whether the 128 or 135 is better for you, or that it's better than another car on the market, that's up to you to decide.



So let's get started!



Let's start with a quick intro:
The first BMW 1 Series started production in 2004 with the E87, and was first brought to the US as 2008 models with the E82 (Coupe) and E88 (Convertible/Cabriolet) which started production in 2007. The most major revision year was 2011, which brought a new engine to the 135i as well as some interior and exterior changes. 2012 cars also saw a facelift, with new lights, and some changes to the interior and iDrive systems. In 2013 the 135is model was introduced and produced in very limited numbers. NOTE that some pre-2013 cars were marked as "135is" on their VIN-build sheets, this is not accurate, only 2013 cars are actually capable of being the 'is' model, we are not sure why it's listed on some earlier build sheets. 2013 was sadly the last year the 1-Series was produced, and they have now been replaced by the new 2-Series.

We'll focus on the E82 and E88 128i for now, keep scrolling down for info on the 135i.


2008-2013 E82 and E88 128i:

Specifications:
  • Power: 230BHP and 200 lb-ft of Torque
  • Engine: 3.0L 6-Cyl N52 (Naturally Aspirated)
  • MPG: Rated at 18city/28hwy
  • Curb Weight: 3,252 to 3,494 lbs depending on options

  2. Electric Water Pump Failure - Symptoms include: Car goes into limp mode, recommended to be replaced at 60k+ miles
  3. Thermostat
  4. Oil Filter Housing Gasket (OFHG) Failure - Symptoms include: Oil leak on front of engine around filter housing, losing oil over time, oil pooling on ground under car or on skid cover. Replace gasket for fix ($300-$900+ depending on shop, DIY possible for mech-inclined individuals)
  5. Windshield Washer Tank Leak - Symptoms include: Fluid runs low often, pool of fluid under car after filling tank. (Potential DIY?)

2008-2013 128i/N52 Maintenance Notes/Requirements/Parts:

Research Resources:

Things to look for when buying a used car, not necessarily specific to 1er's or BMW:
  • Rust! Check the body panels around creases, underneath wheel wells/arches, and check the frame/underbody.
  • Oil! Check the oil if possible, an oil analysis is best case scenario and can be done on the cheap.
  • Coolant - coolant should be one color and clear, if there's white mush/chunks, or if it looks thick, run!
  • Modifications - typically the fewer the better, unless you know the previous owner, try to get a stock (no mods) car.
  • Excessive wear - does the interior/exterior look like it has more "miles" than what's showing on the odometer? This could be a sign of abuse on the car.
  • Vehicle history report - often offered for free now, it's a great way to get some information on the car's history. HOWEVER it is NOT a complete history, and only shows what is reported to insurance. An accident not reported will remain hidden from the report.
  • Alignment - simple but important, if the wheel is tilted heavily to the left or right while going straight, this could be an indication of a past accident.
  • Mismatched paint/components - does a body panel look slightly different from the rest? Is one headlight noticably clearer than the other? All signs of a potential accident and should be investigated.


Recommended Tools for the Do-It-Yourself owners!
  • THE 1ADDICTS SEARCH TOOL!! Seriously, this forum has enough information to hurt your brain.
  • Carly App or other code reader, Carly also allows cool coding features to unlock your car's potential features
  • 3/8" metric hex bit set
  • 3/8" Male & female Torx set
  • Flexible 1/4" and 3/8" extensions
  • Extensions of all shapes and sizes (1/4", 3/8", long & short)
  • Universal joint socket connectors
  • BMW jack stand adapters (or just cut some wood to stuff into the jack points)
  • Quality torque wrench
  • Metric offset box wrench set
  • Oil Filter tool (Any Volvo/BMW 86mm/16 flute one will work)
  • Skinny Spark Plug Socket

ALL CARS Recommended Maintenance Intervals (Note that your car will also keep track):
  • Antifreeze: 60K
  • Brake fluid: 24K or every 2 years
  • Rear Differential fluid: 50K
  • Spark plugs: 80K
  • Manual gearbox fluid: 50K
  • Oil change: 5K
  • Power steering fluid: 24K or every 2 years

Other ALL CARS Notes:
  • Owners Manual and lots of great videos from BMW (this link is for 2011 135i, there are other pages for other years)
  • Amazing site with tons of DIY vids
  • The Bluetooth functionality in these cars is widely regarded as awful. Especially in the case of Android owners like myself, do not expect it to work right.
  • The general consensus for reliability is as follows: 128i > 2011+ 135i > 2008-10 135i
  • Parts can be EXPENSIVE. Just because you can afford to BUY the car does not mean you can afford to OWN it.
  • Whether or not an Extended Warranty is worth it or not is pretty subjective and your results will vary on the car and your own maintenance/driving tendencies.
  • If you buy a 135i and tune it, it is highly recommended to get a stronger charge pipe, as they are known to fail under increased boost.
  • You should only run Shell 93 Octane - anything else is for peasants

Nice thread. I would add Windshield washer tank leaks (definitely DIY fix for less than $100). Seems to be a fairly common issue and one that I'm experiencing right now.

Adding to the main post!

Great idea and thanks for the legwork! I'll try to contribute

N52 problems:
  • Valve cover gasket leaking/valve cover cracking. Symptoms: oil all around valve cover, spark plug threads oily,
  • Waterpump + thermostat
  • Oil Filter Housing Gasket
  • (Not sure if this is still a thing but earlier N52s experienced it) Hydraulic valve lifter tick

If you're planning on DIY, I'd recommend these tools (on top of normal tools you need to work on any other car [metric socket set, jack stands, breaker bars, etc.]):
  • 3/8" metric hex bit set
  • 3/8" Male & female torx set (maybe with a decent bunch of 1/4" stuff for those tough to reach bolts, like the oil filter housing under the manifold)
  • Flexible 1/4" and 3/8" extensions
  • Just a million extensions of all shapes and sizes (1/4", 3/8", long & short)
  • Universal joint socket connectors
  • BMW jack stand adapters (or just cut some wood to stuff into the jack points)
  • Quality torque wrench
  • Metric offset box wrench set

Air tools are fantastic too, my impact gets used quite a bit. Also an electric screwdriver (you'll thank me the first time you remove the engine/trans skid plate LOL)

128i maintenance req's:
  • Engine oil: ~6-7qts of BMW LL-01 Oil (honorable mention: Castrol 0w-40 euro blend)
  • Oil filter: Mann-Filter HU 816 X
  • Manual transmission: 2qts of GL-4 fluid (honorable mentions: Redline MTL, Redline D6 ATF)
  • Differential (manual trans) 1qt of GL-5 75w-90 fluid (honorable mention: Redline 75w90)
  • Spark plugs: NGK LZFR6AP11GS, NGK 6619 LFR6AIX-11
  • Air filter: Mann Filter C 27 114
  • Cabin air filter: Mann-Filter CUK 8430
  • Power steering fluid (CHECK YOUR RESEVOIR CAP) but most likely 1 liter of Pentosin CHF-11S
  • DOT4 brake fluid
  • Coolant: 1gal BMW coolant + 1gal distilled water, mixed 50/50

Still learning these animals, but I had thought the n55 was also a candidate for the intake valve issues? The core DI design is still the same, just changing the VANOS for Valvetronic or whatever that eliminated the throttle body? If I'm way off on theory or terminology here I'll edit this paragraph to either remove it or make it more accurate and keep this thread on target.

Should injectors be mentioned here? I believe current rev is 12, and that they are available via rockauto, amazingly enough, as actual OEM parts for dirt cheap and distinctly easier to replace as a DIY than other DI engines out there- Speed6 injectors as an example

BMWhat (used to be Carly) has a used car check that can be run to get details on service history & mileage- compares data to be sure data points are listing expected values.

Suggest using a VIN decoder like bimmer.what to double check what's actually on/in the car.

Look for oil around the oil filter housing re: OFHG wear- I was looking at pics earlier today if needed for this thread

There's more, but it's dinner time......

Aren't the windshield washer fluid bottle and related parts shared between the 135i and 128i?

A few other things to note: N55 has Valvetronic, N54 does not. N54 uses problematic piezo injectors (which have been revised more than 10 times) and the N55 uses lower cost solenoid injectors.

Minor point as most people will double check before purchasing or installing, but, the plugs for the 128i are shown as NGK LZFR6AP11GS on RealOEM and NGK's catalog. (These are 95712.) Only reason I caught this is because I recently bought a set a very good price even though don't need them now.

You're right, but from what I've noticed is there's a decent debate on what NGK spark plug to actually use.

Quoted from an Amazon review (I know, not exactly the most credible source but it gets the point across):

"The NGK website lists [NGK 6619 LFR6AIX-11] as a recommended plug for the N52 engine. This is not the plug recommended by BWM, however; the Bentley manual says to use NGK ILZFR6D11. I believe that NGK has updated their plugs since BMW made its original recommendations. If you go through realoem.com, they show different spark plugs for different years in the life of the N52 engine. For an '09, it would probably be the NGK PLZFR6A11S, though neither BMW nor Bentley recommend that one either."

-C.A.M (2 years ago on https://www.amazon.com/product-revie...munity-reviews)


Multiple NGK plugs on Amazon have a bunch of positive reviews, all mentioning BMWs with N52s, all saying they run just fine. I honestly don't think it'll make that big of a difference. There's a bunch of threads accross 1Addicts, E90Post, etc. discussing various plugs.

All I know is I bought the NGK LFR6AIX-11 and I haven't had a single hiccup. Performance and gas mileage are great.

___

Some maintenance intervals I found a while ago

Antifreeze: 60K
Brake fluid: 24K or every 2 years
Rear Differential fluid: 50K
Spark plugs: 80K
Manual gearbox fluid: 50K
Oil change: 5K
Power steering fluid: 24K or every 2 years

Adding to the 128i N51/52 engines that the manifold gaskets commonly leak between 80-120k miles.

These cars do not support bluetooth music, only with third party adapters they are able to.

That's all I have since my 28k mile 128i N51 has been problem free.

Can you get injector part numbers for me? That would be amazeballs.

Multiple NGK plugs on Amazon have a bunch of positive reviews, all mentioning BMWs with N52s, all saying they run just fine. I honestly don't think it'll make that big of a difference. There's a bunch of threads accross 1Addicts, E90Post, etc. discussing various plugs.

All I know is I bought the NGK LFR6AIX-11 and I haven't had a single hiccup. Performance and gas mileage are great.

___

Some maintenance intervals I found a while ago

Antifreeze: 60K
Brake fluid: 24K or every 2 years
Rear Differential fluid: 50K
Spark plugs: 80K
Manual gearbox fluid: 50K
Oil change: 5K
Power steering fluid: 24K or every 2 years
Added!

That's all I have since my 28k mile 128i N51 has been problem free.
What manifold? Is this the valve cover you're talking about? That one was covered already. I'm going to note the bluetooth bit but haven't decided how yet. Overall the BT functionality (especially for Android) is just crap.

Thank you! This thread is invaluable - I wish I saw it when I was looking to buy.

And you could say it doesn't support AD2P (I'm pretty sure that's what the bluetooth protocol for streaming music is called).

Also 1 thing to add in the DIY section: an oil filter tool. Any Volvo/BMW 86mm/16 flute one will work.

And to Amazon as my parts store (guilty, I love my 2 day shipping), you can find damn near everything there.

Well hopefully people in the same boat will now have a place to look

Added these points as well and yes good call on the BT protocol that's a good way to nail it down. Thank you!

Update: hmmm can't seem to tag any more people in the list, Jason is there a limit to this?

RE: Fuel injector details-
Reading further into this it seems RockAuto has some issues getting more than just one or two in stock at a time, and they appear to sell pretty much instantly. For their pricing it's worth checking them out, but don't be surprised if they aren't available or they don't have enough in stock to meet your needs.

So, I pulled some data from ECS to provide a baseline for pricing and part numbers. I'd encourage shopping around and if you can find a better price from a place you are comfortable giving your credit card details to, then by all means get em!

And, I'm a noob here still. This info should be correct- hell, it's what I'm filing away for my own use. That said, if I've borked something up please PLEASE speak up so correct data can be had!

N54 Fuel Injectior Replacement
Reference Prices and part numbers gathered on 2016-07-19 from ECS
https://www.ecstuning.com/BMW-E92-33...L/Engine/Fuel/

N54 Fuel Injector
Mfg Part # 13538616079
**Previous #'s: 13537565138 13537537317 13537585261
Price each - $245.49 (BMW Cost- $300.24)

N54 Decoupling Element
Mfg Part # 13537564751
Price each - $8.81

N54 Injector Seal
Mfg Part # 13537584315
Price each - $2.43

It is recommended to replace all six instead of mixing and matching. Vehicles with old injector 7585261 will need to inspect their existing injectors to determine if these can be replaced individually. With an index of 11 or greater, injectors may be replaced individually with a new injector. If the index is 10 or less, all 6 injectors must be replaced. See pic below for index number location.

Replacement also requires 13537564751 for each injector.

In the pic below the index is found after the part number. In this example the index number is 11 (13537585261-11)


ECS offers a N54 Fuel Injector Replacement Kit with 6 injectors, seals, and decoupling rings
Mfg Part # 13538616079KT
Price - $1540.38

The N55 platform doesn't seem to have the same injector issues that the N54 does, but with these prices it doesn't really matter.

Good work! And is this just for the N54 or N55? Or both?

Darn good question!

As a noob I'm still getting a handle on things n54, I haven't yet had the luxury of expanding & cross-referencing what I've learned to the 55 platform.

I'm sure others here will be able to provide that info? I hope?.....

Hats off, Matt. This will be a great resource for new guys AND a wonderful repository of useful information for all existing 1-Series owners. We have a similar set up on the Yamaha FJRForum.com called the Bin o' Facts. It is set up by Generation, as there have been three distinct Generations of this wonderful Yamaha motorcycle. I am inclined to suggest similar divisions for our Ones, but that might result in too much repetition, so I will leave that up to you and the other major contributors.

Also, you may want to include a technical section for each Oner. This could include the following:
Torque specifications for common fasteners
Gear ratios for different tranny setups
Links to maintenance and upgrade videos
Tire recommendations
Aftermarket parts sources
Best OEM parts sources
Group Buys on common upgrades, e.g., exhaust, suspension, wheels
Accuracy of onboard metrics, e.g., speedometer, tach, temp, etc
Dyno test results for common mods, e.g., Dinan, etc.
Paint codes?
Recall histories of each model
Aftermarket lighting alternatives

That's all I can think of at the moment. Hope this helps. Thanks again for working so hard on this!

Perhaps these pdf's will help. I think you should also make a list of all the recalls that effect 135i's and maybe the more common service actions too.

You need to add the N51 engine for the 128i.

Describing what came in options like the Sport or M-Sport package would be helpful.
