@WayToManyAssassins I've got a n46 engine and yeah it's not fast but I wouldn't say it's underpowered mine definitely doesn't have problems getting up to speed
@@diyonlinegarage I saw this video before and it doesn't allow for the thermostat to open nor does it show how to do the higher bleed screw beside the oil cooler housing. But thanks anyway.
@@dhalsim-1 There is a BMW TIS (technical information system) instruction but it isn't worth following it. The BMW original procedure is annoying! Just fill it up and let the engine run until the big coolant circuit opens. Then open the highest screw for bleeding until some water comes out. I think you maybe need to remove some housing for having access to the higher screw, i don't remember exactly. Then let the engine cool down and fill up the coolant to maximum again. Done.
Had the VVT problem, hard to figure out, also watchout for it's sensor and the gasket of the sensor. It's kind od poorly made, wasn't able to tighten mine and it leaked oil and threw out a code (system too lean on bank 1)
greetings, I own an e46 with N46 1.8 and 116 hp, I have never had a single problem, it has 305,000 km, it works perfectly, there is no smoke from the exhaust, the consumption is 7.3 liters. but I'm planning an e90 also with N46 2.0 and 129 hp, or maybe a diesel M47 with 122 hp.. please, stay with the e46 or which one should I choose between the two engines in the e90 that I mentioned? thank you
Have a N42 engine and some of the issues have come to the surface mentioned in the video. One thing these engines don't like is low quality oil and skipping timing chain replacements. Vanos systems go bad cause the spring inside the vanos unite will not retract and can lead to camshaft timing being out of alignment. At least the third generation valvetronic had the issues fixed that the first two suffered from. I may do a more detailed video since I now have tons of experience to share.
@@wonderwalls3565 it's a forum, not a mechanic's workshop, there people talk about things that happened, because they destroyed that engine themselves, I currently have 315,000 km, and I've never had a single problem with the n46, because I maintain it well.. oil change every 7000 km , all filters, the most normal driving, no mistreatment..
I think i have problems with Vanos Solenoid now. While driving seems like transmission and engine shaking bad. I got error for missfire on cyl. 2 and ignition solenoid 2. Is there other solenoid then vanos?
Short answer. dont buy anything with this engine, unless you dont have problems with putting money in it againand again and its not your primary drive.
@@diyonlinegarage How is it a good engine. Valevetronic issues. timing chain system issues. stem seal issues. seal leaking oils. water pump failures. thermostat failure. You could say the last 2 are generl maintenance things, but they are so hard to access on these engines.
BMW N42/N46 4 cylinder engines have no DISA . The DISA issue is present only in 6 cylinder engines ? ?
Yeah, another reason they are underpowered
🤷
🙂

@haydensteinz2268 It's underpowered in the E90 cars, it runs ok with higher octane fuel but still slower than most 4 cylinder engines out there
There's not one video on the entire internet about bleeding the cooling system on these engines

there is one.
Disa valve is not present in n42 and n46 engines...
Second gen n46 has DISA valve
@@Niko31101996 in my N46 1.8 ,115hp has no DISA valve..
👍👍👍
I own n46 and I have experienced 90% of these issues mentioned, including brakes vacuum pump, valve stem seals... poor engine indeed....
E46 or e90 ? Cuz I got a 2010 e90 bought it in 2011 but I changed a couple of gaskets , a servo pump , oil and filter and thats kinda it
@aixalexander5257 yeah a 2010 would be better with less issues
Yes🙂☹️

I have changed the sensor but still the same☹️
@@diyonlinegarage what code is your car throwing?
The most expensive issue on these is valve stem seals. and its bound to happen.
👍☹️
Clogged Pcv plus faulty oil level sensor can lose you an engine so look out for that.
👍

2.0 n46 is ok
👍👍👍
dont buy N46 engine. look at the forum where the people who know about BMWs talk. they say never buy N46/42 engines.

It is a pretty good engine but valvetronic seems to be poor ☹️
@@diyonlinegarage How is it a good engine.
Valevetronic issues.
timing chain system issues.
stem seal issues.
seal leaking oils.
water pump failures.
thermostat failure.
You could say the last 2 are generl maintenance things, but they are so hard to access on these engines.
forgot the oil filter housing gasket leaks. and ofcourse coolant leaks.
@@wonderwalls3565same issues what a m54/m52 has too so stop talking lmao (not valvetronic)
👍🏻
Why using A.I. generated voice 😀
I don’t need microphone 😀
🔝🔝🔝🔝….
This engine and DISA? Hmmm
🤷
