welcome back everyone its mark with exotic art playplace standing in front
of the e60 m5 today is the next next video in the series of videos talking
about the top 10 things that you need to know about the e60 m5 and so at the end
of the video I'm gonna feature three things if you stick around long enough
I'm gonna show you a before and after startup so a cold start I'm gonna show
you the exhaust and the engine sound and a hot running engine and exhaust sound
so I'm going to show you both of that at the end as well I'm going to explain to
you the next video in the series which will be later this week of course I'm
gonna give you that little hint as to what's going on and as well I'm going to
give you the three things the three solutions to improving the sound if you
don't like the sound of the e60 m5 at cold start there's three things I'm
gonna throw in at you at the end and you stick around to the very end you'll find
out exactly what those things are but before we get rolling you make sure you
give my my channel a like thumbs up of course don't forget to share it with
your friends and most importantly if you're not already subscribed to the
channel make sure you do subscribe get onboard
follow lots of great East 60 content and a lot of great supercar content as you
probably already know I Drive Lambo I Drive this not any other anyway so
moving right along so for those of you who know the e60 m5 they make a lot of
interesting noises when they're very cold some cars start them a cold warm
they always sound the same that is not the case with the e60 m5 these cars put
out a very very peculiar sound almost a kind of noise that is puzzling and
worrying to a lot of owners especially if you've never heard it before and if
it's your first time starting one of these up you probably get a little
stressed out at first and I see a lot of the guys in the forums start asking the
questions they say hey I just bought my e60 m5 it's making these weird noises it
sounds like a diesel motor what's going on with that car well yes in fact and
you've probably seen Tiffany dal in some of his videos in fifth gear you've
probably seen some of the other guys and and critics talk about the cold start of
these cars so not only do they have a noisy exhaust note but they actually
sound like a diesel engine on the front and the diesel engine they get very
rockety and kind of make a lot of noise and that's like I said very disturbing
for some people so what causes this this really in essence is BMWs way of
regulating the fuel mixture to ensure that you get a faster more accelerated
heating of the catalytic converters so the car can heat up more quickly and be
more efficient in its performance of course so how does it do that well
primarily what's going on and there there's some timing things that are
happening there's a secondary injection air pump but more importantly the big
thing is actually the leaning of the fuel and if you're not sure if you're
aware of that or not when you rich enough fuel mixed you're
typically things cool down because if you'll believe it or not actually cools
if you lean the mixture what ends up happening is you you can create a
detonation situation now because the car is idling at cold you're not worried
about that but it leans it up so that it creates excess heat in the exhaust which
therefore transfers through the catalytic converter gets that heated up
and allows the car to run more efficiently now for those of you who are
worried that you know my car's making a lot of noise is this something I should
be worried about well trust me when I say with the e60 it is so full of
complex engine management systems that if anything was slightly out of kilter
or out awry the systems are very sensitive in these cars and what you'll
have is a case where the car actually spits out a code and it goes into limp
and dump mode so you'll know pretty quickly if there's something not really
firing there properly you'll know if you're running low or lean or you're
running basically missing cylinder firing orders or some kind of problem
like that you'll know about that in a hurry the car will spit that code out
for you okay so now here we go we're gonna fire it up you take a listen I'm
gonna sample the exhaust and sample the engine note and of course we're gonna do
that now and I will also give you back to back the sample of the warmed up car
and then I'll explain to you the three things that you can do to fix this
problem
the sample of the warmed up car
so the three things guys that you can do if you don't like the sound of these
cars on a cold start number one put a race exhaust system on there
then you don't hear it number two sell the car
I guess unfortunately that's the one of the things about these cars some people
love it and some people don't love it I'm pretty much used to it it doesn't
bother me I know some people I've heard on the forums that are embarrassed by it
and when there's somebody who doesn't understand the car they ask why is your
car making so much noise so I ultimately you can sell a car
that's an option another third option which I do not recommend I know it's an
option when you get those those tuners that you can adjust and make some code
changes within your computer you're able to actually do the cold-start delete on
this and you can actually wipe that out a logic altogether and let the car warm
up as it normally would in any other car now again I don't recommend that again
it's part of the protective system proud a part of the way to advance and help
the car move things along so I would always recommend leaving status quo on
that regard so everybody I hope you enjoyed that video you make sure you
give it a thumbs up like of course comment below I'd like to hear your
opinion on it don't forget to share with your friends and of course most
importantly if you're not already a subscriber be sure to hit that subscribe
button we'll talk to on the next one
oh and by the way the next video we're gonna be talking about the sliding
tachometer in these cars a very unique fun feature very few cars run but we
have that I'm gonna be talking a little bit more detail on that thanks again
everybody Marc you're signing out talk to that bye bye
