Great info for N20 BMW owner. I have replaced valve cover(include gasket), spark plug , oil filter housing for my 2015 X3 28i (manufactured in Nov 2014). Recently got multiple engine misfires and one Fuel Pressure too low codes. The error went away after the reset was told to replace fuel pump if the code comes back.
Folks, should be common sense. If are unable to afford repairs on thesw cars stay away from high end cars. Unless of xourse you are a experinced mechanic. You can buy used at a decent price but the maintence/repair cost require deep pockets. 😮😂
I have a 2018 320i just tuned to bm3 stage 1 81k miles. Planning it to keep it stock. should i be worried. i do oil changes every 5k miles with liqui moly
I bought a 2015 428i xdrive 70k miles ive owned for 1 year 106k nothing but problem's At 87k ive put a rebuilt head and gasket timing kit new aluminum valve cover complete tune up spark plugs ignition coils and oem thermostat Now at 106k its broke down thinking its water pump biggest money pit since owning And i went from a 2014 e550 4matic v8 biturbo to save $ on a daily The 428i coupe is a beautiful car always getting compliments
And the problem with your little engine is that there are two missing cylinders as well. Either get a 4 for economy or an 8 for power anything in-between is a joke.
Hi i bought a 2012 bmw 528i x drive for 11k lease it has warranty for enegine and transmission for 24 months the car has 106k miles the timing chain already been change should i worry ?
@@8020Media just adding that this is my first 4 cylinder BMW engine and I drive bimmers for the last 30 years. 6 cylinder are much better BMW engines. Not perfect but better.
Missed another big one. The mechanical vacuum pumps go bad and suck oil in to the vacuum system. Particularly problematic if you have the vacuum controlled wastegate.
i think the n20 is a great engine all timing chains on any car need to be inspected after 9 years any way so you might as well replace it then and what car isnt leaking a bit of oil after 100k km
Can i suggest you put a difficulty factor in the repair? I have had my Rocker cover gasket go and was advised to replaced the whole cover as they get brittle. I now need the sump gasket to be replaced. Good to hear the heads up on the timing chain however
I have had 1 replaced. If I knew then what I know now, I may not have had to replace it. Mine was the oil pump. I now have 100k on the new motor knowing what to look for. I change the oil more often than I should, plugs as well, and had the head gasket replaced at 50k out of caution. Runs like it did when I had it put in
@@gnt4l I would get these random low oil pressure warnings. They would appear, and then clear and not be seen for weeks, then return. This went on and off for nearly two years, and they could not figure it out. Finally it returned, and when it did it was different as this time the car started acting very odd and the temp shot up. As luck would have it, this time the shaft on the oil pump actually broke. Everything looked fine structurally from the outside as the belt and such were still attached and moving, but I believe the shaft broke very close to the impeller, so everything stayed in place and nothing leaked. Apparently they issued a TSB on this a few months later. Never were able to determine why it went intermittent for a couple of years before it went catastrophic.
It's simple - the valvetrain drive, which is the only serious problem can be replaced for around 1-1.5k$ while vehicles with this engine tend to cost 3-5k$ less than alternatives. I've made 140k miles in mine, 0 issues so far, but I'm planning to replace that valvetrain drive just in case.
Plastic drain plug on plastic oil pan not that it’s a bmw problem but an oil change is one of the most frequent things outside of pumping gas that an owner has to do and the average person is not going to BMW for an oil change which mean diy. Buying these parts from the local auto parts stores sometimes the plastic drain plug comes with the filter and it causes tons of problems leaks strip, it doesn’t fit right or you may over torque it. All of this is rare with your traditional oil, pan and drain plug.
I have a misfire that comes and goes and now the engine stumbles and seems like the turbo turned off…since there’s no power service sucks where Iam at any known problems cause a misfire like thy?
Troy - Do you have a Check Engine Light? We would advise getting an OBD2 code reader cause it will quickly help you diagnose the issue. From the sounds of it, it could be an ignition component (spark plug/ignition coil).
hi, the oil light came on on my 2013 N20 (328i) and temp gauge showed it was overheating so I added a quart of oil and all of a sudden white smoke was pouring out the exhaust and the engine won't stay running. Turns on then immediately dies. bmw mechanic said its a turbo problem but white vapor tells me head gasket. Would you have any thoughts please??
@@8020Media Yes likely HG, but I fail to see how it could possibly be turbo related!? Is there a seal failure in the turbo that could allow water vapor out the exhaust!? Thanks again for thoughts
N 20 is the worst engine bmw has eve made, that thing can jst fail while driving no warning light no nothing, I have about 8 engine um rebuilding nw , it's very hard to rebuild, it needs original Crankshaft bearings ,. If you use these after market Cranks you will never win
anyone has any idea why my f30 320 n20 car will go rough/growl during heavy rain or going through small water puddle? It's like the car cannot go fast and if i press gas, strange vibration, i had to drive 60kmh for quite some time until it went normal again. Strange no error. how do u fix it ? If it's dry or light rain no problem.
@@beaugator i see, i also noticed my coil plug had this rust, if this normal? Just changed all 4 coil plugs and 4 spark plug early this year. How water could enter the coil while i had cover on top of my engine, how do i prevent that? Also, bad news my 320i stage 2 , just went kaput on cylinder 4, 20psi , low compression. *Sad*
@@shahosj5023 Any rust should be treated and protect the connection against further corrosion with dielectric silicon. It will protect against water intrusion as well. The low cylinder pressure could possibly be from a too tight valve adjustment. you need to do a leakdown test to see if it's the rings or the valves leaking.
want to buy a n20b20 220i 2014 with stage 2 tune 278 hp 90 000km is it worth it or are the engine realy bad. Gonna use all my money dont got alot left for engine fix but can of course do normal maintance.
Erling - We aren't going to give advice on if you should buy it or not, especially given the budget constraints. But what we will say is if the maintenance has been kept up with, it may not be a bad buy.
I’m in the process of buying an f30 and getting a 320 or 330. Would it make sense to pay the extra money just to get a B48 to avoid the issues of the N20?
Chhem - Personally we prefer the B48 over the N20. Toyota uses the B48, with some slight changes, but that says a lot about the engine. However, make sure to abide by your financial situation.
Y - Nope! You should be good for many more miles before thinking about the timing chain. However, make sure you stay on top of maintenance. Lack of maintenance intensifies other potential problems.
