Your future just got less promising...
Mine (May 2011 build - VERY early N55) was just diagnosed with a failing HPFP. They're still diagnosing to confirm.
SO confused. Dealer says 13517616170 is latest/best part for my car. $860. ECS has that one, REMANUFACURED!, for $895, but says NEW $411 13517616446 is latest and greatest and most reliable. Tischer (GetBMWParts. I guess they're Silver Spring BMW now or some such thing) has the 446 for $300 but say IT's remanufactured. Want $628 for the 170 unit. They also say they're open 'till 6 online, but 5pm on voicemail. So no answer.

I have no idea how much my indy/mod/race shop wants for one yet. According to the DIY on N54Tech it's about a 45 minute job. We'll see.

They also mentioned my Oil Sensor is leaking into my wiring harness so the harness!?! will need replaced somewhere down the line. But didn't want to discuss replacing the sensor...

This thread is depressing. I'm going to do a little work, then read up on how much fun these things are to mod, and to drive! 'Cause they sure are.
I still wouldn't classify the amount of problems as "overwhelming", but I think they just reached the realm of worse than most cars out there. After 30,000 miles in my care (74,400 total on the clock) it's needed a brake sensor, the coolant reservoir, oil filter housing, and now HP fuel pump.
Flat caused by pothole and wiring harness splice caused by rat notwithstanding.

N54 Preventative Maintenance at/after 100k miles

I'm a relatively new 135is owner (almost 10 months) and I maybe should've done more research before purchasing an N54/E82 with 121k miles. Needless to say I'm far from disappointed. The car has been an absolute blast to drive, it's handling is unlike any car I've driven in my life so far. Life before BMW was dull. Due to the recent issues I'd say my 135 is not quite as reliable as I would like, but she's just over the 100k mile hump and almost 10 yrs. old.

Now at 130k miles I'm trying to be a preventative BMW owner and determine what else could go wrong; I've been in the shop every 1-2 months since purchasing and based off service history I don't know what might be problematic in the coming weeks or months. I'm aware that BMWs have major issues in 10 yr. increments, my BMW of Nashville rep. (Kevin Dittler) says that my catalytic converter will need replacing and possibly inhibit my passing emissions testing in my county (TN).

I'm seeking experienced BMW owner suggestions/insight for preventative maintenance for 135is over 130k miles?

Service History:

Jan. 2016: Ignition Coil REPLACEMENT (6)
May 2016: HPFP REPLACEMENT
Jan. 2017: Rear Brake Pad, Sensor, Rotor REPLACEMENT
Mar. 2017: OFHG and Cooler Gasket REPLACEMENT
June. 2017: Vanos Solenoid Valve REPLACEMENT
July 2017: Water Pump and thermostat bled system REPLACEMENT

*aside from oil/filter change in Dec. 2012 there is no service history per Carfax reporting.

You have a 135i not 135is, and it looks like you have done almost all of the maintenance you need. Only other things that may need attention are spark plugs (good for 60k miles) and belts/hoses (which may be good shape). For me, just brakes and tires alone make this a more expensive car to own but that should be much better for most drivers out there who drive normally.

For me, other than water pump I have had 0 issues with my '12 1er.

I realize it's more economical to buy used but I like to start with a clean sheet of paper.

I break them in properly and aggressively service them (1st oil change at 1200 miles, then 5K oil changes, etc). Professional detail a few times a year. I understand this costs me more but it's worth it to me. If my 1er was to get totaled today I'd probably buy a new M240i and keep it for as long as possible and treat it the same way.
Same philosophy here. Have a 09.135i: window issues early on, fixed under warranty. It didn't always open or close upon demand. One HPFP replaced. No other issues; however, I feel like it may just be a matter of time before other gremlins surface. Currently have ~46K miles. I'm torn between enjoying it more or getting rid of it. Sometimes it feels like playing 'German Roulette.'

I also have a 13.135is with 26K miles. No major issues, just a hood lever malfunction two weeks out of warranty--but they did the right thing and fixed it for free. Knock on wood. Again, I don't know when my luck will run out.

I have relatively low mileage on all my BMW's ( I also have a 98.mz3 with 67k miles: no issues--just worn parts) because I've always used another car for my daily driver. I've had a 'sacrificial' Taurus, and two Corollas for that purpose.

I'm thinking seriously of moving on to an M2 (fingers crossed for the GranCoupe version) in a few years and getting rid of the two 135's.

I've had my 135i for about a year now and did new turbos, all gaskets and seals on the motor, injectors, coils, and spark plugs. Everything ls been running perfectly since I've done the maintenance. Keep in mind, I've been FBO running 18 psi for the last 6 months and not one hiccup. If you buy one properly maintained, you should be fine.
