Hey what's up guys Cristian here from Vehicle Virals, I thought I'd do something different today with this video
I'm gonna be talking about my own personal vehicle the 2008 BMW
335i
We're gonna be talking about some of the reliability issues and some problems you might encounter in fact any of the n54 engine variants
So it doesn't necessarily have to be the 2008 BMW 335i. If you haven't already subscribed make sure and subscribe
For weekly automotive content, let's go ahead and hop in the car and begin this video
Alright guys so the first problem you might encounter with the n54 engines similar to the ones in my car the 2008 335i
Is the high pressure fuel pump that's probably one of the most common issues
That happen in the BMW the high pressure fuel pump is responsible for injecting fuel into the engine
If the fuel pump fails, then your engine won't get the proper fuel offer it to run properly
It's a very common issue
among the n54 engine
BMWs there's some good news
And there's some bad news associated with the high pressure fuel pump of it wherever to fail on you
Let's go ahead and start with the good news so
BMW acknowledged that it did have a faulty high pressure fuel pump that
Prematurely fails, so they decided to recall the part they also extended the warranty once they recalled it
The warranty for the high pressure fuel pump is up to
120,000 miles and 10 years with the quick thought you might think man, that's a great deal
cars coverage for a while so if you had a car
That's within the 10 years in the 120 thousand mile warranty, and your high-pressure fuel pump was to give up well guess well
you're covered you can pop into any BMW dealer and
get that fixed at no cost so this is where the bad news is let's say you were to buy a
2007 BMW
335i you're pretty much out of that window assuming that the recall
hasn't been done in that car yet and
It just happens to fail when you purchase it
Then you're you're pretty much already outside of the window for the recall so they won't replace it if it fails at that point this
Is the thing with my observation I've noticed that most people that do own
BMW 335i eyes they're high pressure fuel pump was already you know replaced back in their early stages at twenty thirty thousand miles
So if you were to find one right now, let's say with higher
There's a very big chance that that recall has already been done in the high pressure fuel pump
so it shouldn't be that big of an issue the price for the high pressure fuel pump is around four hundred and fifty bucks and
That's not even including the labor ouch, but like I said
It's very rare to find a BMW that already hasn't had that part service in the past because of the recall
So it shouldn't be that big of an issue
So how do you know if your high-pressure fuel pump is bad here are some symptoms?
Long cranking when you try to stop the car
Let's say it takes five six or seven seconds to start the car that might be because of a faulty high-pressure fuel pump
Also your car can shake let's say you're just driving normally and your car just starts to shake and it starts to lose power
In my case when I went through this I would try to floor the gas
And it just wouldn't go anywhere the car would just shake
I floored it
The car goes into like this limp mode the safety mode that it's trying to protect itself from further damaging in itself
That can be a symptom as well, so if you have you experience any of that?
it could be that your high-pressure fuel pump is bad the next problem is experience with the
335i is the electric water pump the electric water pump, which is another fragile part
Which is responsible for pumping water or coolant into?
The radiator in order to cool the engine um both the water pump in the radiator are very important parts to your
Cooling system from others that I've talked to there water pump gave out around. Let's say 70 or 80 thousand miles
My personal experience my water pump gave out at around 61 thousand miles
I remember paying almost a thousand dollars to get it fixed
Obviously not going to the dealer the dealer would probably cost me fourteen fifteen hundred dollars to get it changed including parts and labor
I went over to like this European shop
and they charged me close to $1,000 dollars to
Repair that, but what happens is when you replace the water pump on one of these cars you have to also replace the thermostat
And that's where the added cost comes in some symptoms that you might get to know that your water pump is bad
Your car starts to overheat if you look at the temperature meter. That's on the cluster. They're
typically anything over 250 degrees Fahrenheit
It's it's not normal, so I would definitely get it looked at another symptom
Is that your car gets into like this lint mode like I said previously you lose power
This slows down you also get a warning light that tells you a bunch of temperature as well
I remember when I first went through it my car. Just decided to just
lose all of its power and
Then I had the warning that I was reaching unsafe temperatures, and then the car showed up
And it does that like like I said before it does that to protect themselves
There's really no shortcut to fix this problem
You just have to buy the part make sure you buy the OEM part don't take any shortcuts
when it comes to this particular issue
so
the third problem you might experience with a
335i that is pretty common as well is oil leaks from the valve cover. There's two reasons
why your valve cover can be leak and it can be either the
Gasket or the cover itself when it comes to the gasket there
They're prone to degrade and pretty fast and the valve cover is made out of plastic which is very prone to cracking
Because of the high heats that the turbo engines produce so the biggest issue here
With that problem is that you don't get any fault codes or any kind of warnings
That you are leaking oil from your valve cover
That's one of the things where you would kind of have to observe it some of the symptoms
You might get from the oil leak from the valve cover is
May be a possible
Burning oil smell coming from the engine bay
Also, you might get a warning that you're low on oil
Depending on how much is leaking if it's leaking a lot or a little bit at a time if it's the gasket
It's not too bad of an issue it's only thirty two dollars to replace, but if it's the cover
You could only imagine how expensive that and if you change the cover you're gonna have to change the gasket as well
So I think if you get the combo for both the gasket and the cover you're paying anywhere around
450 bucks
Whoo and that does not include the labor so the fourth and last common problem you might experience with
BMW 335i with the n54 engine is
It's probably the worst one in this list and about worst. I mean it's the most expensive one to
Repair and that is turbocharger failure and westgate rattle and
typically when you have this issue
It requires you to get two brand new turbos so the function of the westgate is to is to control the maximum boost
created by the turbos to protect both the
Engine and the turbochargers some of the symptoms
You might get is your hair rattling and coming from the from the engine almost like something inside of a tin can especially when you
Hit the gas and breath you'll get loss of power
So you'll be able to tell that your performance is not as optimized what it normally is aka limp mode
You might even get smoke coming from the exhaust because you got oil leaking from the turbo seals
I'll tell you this if this issue were to happen to you. It's almost just better to get brand new turbos
Upgraded turbos not the OEM ones you're already gonna be spending over a thousand dollars for the turbos
And it's ridiculously expensive to - for the labor
I think it takes anywhere around 16 hours to replace those turbos
So if you're gonna go ahead and spend that you might as well pay an extra a little extra and get some aftermarket
Bigger turbos get some performance out of it, anyways guys that was a video. Hope you guys liked it
Hope you guys found it informative. It did hit the like button
Don't forget to subscribe. I'm thinking of reviewing at this specific car
I want to get into car reviews in general, and I think I'll start with this car so if you don't want to miss that
Hit the subscribe button and don't let this list make you not want to buy this car
This is just worst case scenario
And if you did have to change these parts on you wouldn't have to change them again for a very long time in my scenario
I've owned it for three years the positives outweigh the negatives
In my opinion. Hope you guys have a good day. Thanks for watching until next time
