Рет қаралды 194,602
Күн бұрын►The BMW N20 and N26 engine is the turbocharged 4-cylinder successor to the BMW N52 engine. BMW created an engine to match the N52's performance while being smaller and more efficient. Produced from 2011 through 2017, the N20 has been succeeded by the BMW B58 engine. During its production run, the N20 and N26 engine was shoehorned into an array of BMW models such as:
-BMW E84
-BMW E89
-BMW F10
-BMW F15
-BMW F22
-BMW F25
-BMW F26
-BMW F30
-BMW F32
-BMW F34
In our BMW N20 engine diagnostic guide, we cover some of the main points you need to look out for when buying or owning cars with these engines, including:
00:00 - Intro
01:04 -Timing chain & timing system components
05:06 -Waterpump & thermostat
06:29 -Ignition coils and sparkplugs
08:40 -Serpentine belt & belt tensioner
09:53 -Oil filter housing gasket & oil cooler gasket
11:38 -Fuel Injectors
13:38 -High-Pressure Fuel Pump
14:54 -Camshaft and crankshaft position sensors
17:00 -Engine cover & PCV
18:08 -Valve cover & valve cover gasket

Ppl tell me I'm nuts but I change oil every 5-6k km. Yes, km not miles. Had Subaru w/turbo prior to bmw, had almost 250k km with 4.5-5.5k km oil change intervals. Sold it to my friend, he had it until almost 300k km then sold it off. On original turbo. And I tell everyone with turbo engines, change your oil every 5k km. Great video, thank you!
@1Bigduff 3 жыл бұрын
thanks for giving me about 28 reasons to not sleep tonight :) great video. totally agree about oil change interval. I had a 2015 528 that blew the HPFP at 50K miles, plus an injector. that sucked! I also have a 428i and absolutely love the motor and car. I have really good BMW mechanics that keep up on maintenance. I'm fine working on my 1997 F-150, but not on this car. also too much plastic. but I love watching your channel and love your videos. wife has a 640i. runs like a freight train - or at least the way she drives it does :). not cheap cars to own, but I don't want to drive anything else. :).

Honestly, this is SOOOOO ridiculously helpful...really do appreciate it. I'm just learning about this engine (I have a 2013 X1) and I find all of this really fascinating. I just bought a basic diag tool also so I'm stoked to use it to help figure things out. There's something about at least having some rough knowledge about what's going that puts me at ease. Imma a little disappointed learning about the timing chain issue with my model year but still fairly low km's so hopefully I can figure something out...

Gareth, it would be great if you guys could cover an episode speaking about the the PCV valve and when to carry out this service. Mine failed and had a tough time figuring out where the whistling sound was coming from. Just got my valve cover and waiting to change this out.

Great so far. I've put 25k miles on it from the 50k it had when I bought it.Changed the plugs at 60k, just got brake fluid swap and new rear pads at 75k, no oil leaking, no coolant leaks. It's been as reliable as anything else I've had, and I've had over 20 different cars. What's most impressive is how solid everything feels. No rattles, no squeaks, just feels tight and runs great. I'm sure around 100k I'm gonna need an alternator and stuff like that will start going out, but it's paid off so it's worth it to repair because I really just enjoy driving the car.

The timing chain seems fine still, and I am going to do spark plugs when the weather gets warmer. I will definitely take your advice and shorten the oil change interval from 15k kms to 10k kms.

did your turbo quit? what were the symptoms of a bad turbo? 260k is well broken in lol. kinda makes one wonder about changing the oil earlier than bmw recommendaton. i have ax x1 and change the oil at 10K .

Did the belt and tensioner, have the plugs and coils on order. Planning on doing the ZF trans svc and diffs as well. Only 50k miles now, but recently retired so want it to last trouble-free as long as possible.

I have a March 2015 build 2015 BMW 328i xdrive (apparently ok for the timing chain bits as that was the cutoff time...). Although I do have new spark plugs and Eldor coils on standby as I’m at 81,xxx KM, I’ve only had to replace a slightly leaking fuel injector, front shock (most likely succumbed to a pothole lol), battery (yay Costco AGM!) and an axle seal for my drivers side this weekend. Oh and rear brakes and wear sensor. Bought it at 61,xxx KM and I’m still very happy with it. Knew there is typically more maintenance on luxury vehicles. All in all an amazing car (8 speed auto) with great acceleration numbers and the fact that I can get 5.8-6.0L/100KM or virtually 40MPG on the highway at the 110KM/HR over multiple hours of varied elevations at the speed limit at around 0* Celsius is awesome.

Been searching thr web for a full break down on how to maintaine the "N20" engine and I happen to land on this GOLD MINE! Outstanding video as always guys, very informative and keep up the astonishing work. 🤘🏾 Everytime I push that start button I can never tell if the chain is creating excessive noise or if it's just the direct injection valves opening and closing. Even after watching your short demo clip. I got the 2016 ix M sport with about 50,000kms, upon start up the engine is quite noisy... As stated it's unclear if it's the chain or the DI however after about 30sec the rpms falls below 1k and the noise is completely gone. Some say it sounds like a "dying cat or supercharger" when you rev an engine with chain problems but I'm not getting that sound. Would love your 2 cents in this. Much love from Canada! 😎

Great video! I had a ruptured breather diaphragm that was causing a squealing noise. Was able to replace it without the entire valve cover - $50 and 10 minutes. The turbo oil feed update was to fix blue smoke on startup after sitting for a few days. I had this issue (embarrassing) and the updated line solved it. The electronic wastegate actuator also failed, which I replaced at the same time. I am at 110K miles and otherwise (knock on wood) it's been a very reliable car. Still paranoid because of the timing chain issue and pending failure...

Apologies for adding to this two years later, but so it happens that I managed to get myself two N20-based cars in the meanwhile. One 28i-245hp and one 18i-156hp version. Both had same fail mode which is worth mentioning: failed resistor in thermostat. On US spec cars, I understand this leads to a check engine light and some limp mode as this feature is part of emission controls. On EU spec cars (which mine are) you only get a "MAP thermostat open circuit" code. And your fuel consumption goes through the roof, while the engine is probably in some limp mode - half asleep. No other warnings. On the 28i-245hp - an X3 mostly driven in heavy city traffic this drove mileage down from 17 -18mpg down to even 11mpg (13 l/100km to 19l/100km). Pretty easy fix and with immediate return on better mileage. As far as I can tell, without the thermostat resistor, the mixture is never allowed to be lean. Oil temps never jump above 100degC when fault is present

we have a n52, good engine besides the leaks BUT the mpg are trash vs the n20... n25 is 25% better @ a minimum

Great video, jump stumbled upon your channel. Awesome content, subbed! Got a 428i with N20 from 2014 (tuned stage2). Absolutely loving it. Planning to keep it for some years still, I am not very technical myself, but this video gave me some good insights on what preventative maintenance to plan for. Provides me with some background to talk to the BMW specialist shop. Cars got almost 150K kms now. Based on your suggestions I'm thinking on asking some quotes for the 4 main things I distilled from your video: timing chain/oil pump chain, serpentine belt+tensioner, oil filter housing gasket+oil cooler gasket and possibly a valve cover. Doing it all at once should save some labor hours right. Anything I should add while doing this at once? Any rough estimation on total labor hours this could take? Thanks again for the vid, great stuff!

Took my 13 328i xdrive to the dealer since I believe the noise is from the timing chains and was told that it isn’t. Kinda odd since it sounds just like the short video you posted. Just rolled over 89,000 miles.

Ohhh...just got a 228i...so pretty much all the issues of earlier 6's and some new ones with turbocharging and plastic materials...but at least with compact design and improved room in the engine bay our hands won't get much scrapes....well thx for that at least .. BMW

Good video. I purchased the valves cover gasket from you guys and ready to replace it soon. It arrived fast and on time. Thanks. Just need a little bit of idea that, my idle issue. When I crusing on the road. The RPM will drop down to 1100rom. When I want to accelerate the car. The sounds like accelerate from the wrong gear. I was thinking, is it the coil issue or fuel pump issue or something else? When I use manual shift gears. There is no problem, because the rpm stay higher. Just need some light. Thanks

Thanks for the video. Is it possible to replace the vacuum pump seal along, without detaching the valve cover? Our local BMW dealer said that replacing the seal must be done along with the cylinder cover detaching. I have a F10 with N20 engine you are explaining in the video. Please show me a tip for this. Thanks in advance.

My 2015 228i just turned 100,000 miles. Only problems were a battery replacement (expected) the negative terminal cable with chip (disappointing and a suprisingly expensive part!) and a wheel sensor tripping a code (frightening but easy diy replacement) BUT suddenly i have an oil pan replacement lined up. (Cant diy that. Paying $1200 for aluminum "upgrade", hopefully) I discovered the valve cover is leaking when i just replaced my coils and plugs. Plugs and coils, routine and expected. OEM valve cover coming from FCP, and will tackle that thanks to KZfaqrs. Will probably do the oil filter gasket as it will most likely leak soon if not already. Now terrified about the timing chain. Will watch the diy videos for chain replacement. Conclusions from 8 years of ownership? Fun and reliable car if you can afford to buy and replace in warranty. OR buy if you are diy savy and have a ton of tools and time. I'll definitely be going to Lexus/Asian in the future. OR EV once the next generation solid state batteries are routine and recharge time shortened range increased. ICE engines have just become too complicated and hitech as many mechanics/dealerships increase rates to $200/hr plus.

Have an N26 in our 2016 428 F36 GC and its been terrific. I have taken over the maintenance including 7500 mile interval oil changes with LM Molygen. I did have a limp mode resulting from plugs/coils around 60k but replaced with OEM Bosch. It has been running great since and just topped 80k. The timing chain issue seems to have been fixed post February 2015 from what I have gathered and you can determine this by opening the oil filler cap and visually inspecting the chain guide-I believe orange is pre 2/15 and white is post 2/15.

I had a 2014 328 with almost 150k miles on the original timing chain before it got totaled. I learned about the timing chain issues after I bought the car I miss the car and I’m looking to get into another bmw I’ve been trying to convince myself on getting a n20 again. The only issue I’ve ever had with that car was the charge pipe broke at the joint near the air filter and the damn turn signal socket otherwise it was a great car

@faresbotros9884 2 жыл бұрын
What should the hpfp pressure be? My diagnostic tool also shows 98 psi for the hpfp and 7.57 mPa for the fuel rail pressure (that translates to 1099 psi !) It's running rich; I suspect it's the hpfp. I can't tell if it's leaking fuel in the crankcase. I've already replaced the MAF and both MAP sensors without luck. Thanks
