Such a waste... More trash, more dirty manufacturing, more problems.
It's even worse with modern cars. Peugeots have a life of 4-6 years, or 150000km. More than that and they start breaking down. You can get turbocharger failures before you hit 100000km. It's not just them, Mercedes have a partnership with Renault and Nissan and use their crappy engine in their small cars. Reputation destroyed.
15 years ago a Mercedes could do up to a million kilometers without a major overhaul, nowadays I assume they are only slightly better than the frenchies...
I was having turbo problems on my 2002 1.9 TDI Skoda recently. Acceleration in general wasn't very nippy, and going up a hill resulted in things sorta bogging down and the engine not being willing to get above 2,000 rpm.
I'm sure that if I'd been stupid enough to take it to a garage, they would have told me the turbo needed to be replaced, and the price of that would be more than the value of the car. (It has sentimental value to me, though, so I'm reluctant to scrap it.)
When I looked into the symptoms, I decided that it sounded like the variable vanes on the turbo were blocked with soot and exhaust crud, and I came across some YouTube videos where people demonstrated how to fix the problem very cheaply. You spray oven cleaning foam (the stuff with sodium hydroxide in it) into the exhaust side of the turbo, let it sit for a couple of hours, manually work the turbo actuator as much as you can every ten minutes or so, top it up with more foam when the stuff subsides, and then take the car out for a hard drive to blow all the loosened crap out.
I gave it a shot, and it actually worked. There's a fairly long hill near our home that I wasn't able to get over 40mph on before, but on the clearing out drive the car hit 70mph on the way up and it was still accelerating as it approached the crest. I wouldn't say the car has the same acceleration it did when it was new 140,000 miles ago, but it's a whole lot better than it was, and my OBD reader doesn't show an overboost error any more.
Of course, if a turbo fails due to oil leaks or fucked bearings, then you really are screwed.
The thing about turbocharged cars is that a lot of people don't know how to use them properly. A turbo loves higher revs and wide open throttle.
Before VGTs, turbos only worked in a small rpm range. You had lots of lag where nothing happened at lower revs, sudden burst of acceleration you weren't ready for and more nothing near redline. (One reason I want to buy a Saab 99 Turbo)
But modern VGTs work from idle up to redline. Hell, Mercedes even use compressed air from the turbo to start. Any damage to the turbo, or a ripped turbo hose and car will not start on the first try. And if you baby a turbocharged car, only change gear at low revs and generally drive slowly, or in the city, sooth builds up. You have to get rid of it.
This is where the "Italian tune up" comes in... Older turbos had the same problems, but more often. The solution is to drive flat out, or at high boost as often as possible to keep the temperature high enough to burn away sooth.
This technique still applies to modern cars. I like to do a top speed run, or at least a 150+ kmh drive on the Autobahn/ quiet road nearby once a month to burn away carbon deposits.
Hell, I had to clean both turbos in my E420 after I bought it, cause the doctor who owned it before me drove it like an undertaker. DPF was clogged (got rid of it), error codes on the EGR (also cleaned) and insufficient boost.
Had the dealership (friends) take off the turbos, so I could take them home and clean them. Access to V8 turbos is a bitch and a half.
After cleaning I applied a bit of high temperature resistant lubricant to the turbines themselves.
Had them installed back in the car and let it idle for 10 minutes after I started the engine.
Car runs like new. 400hp and 950Nm after tuning, she'll smoke the tires until she reaches 100kmh.
But yeah, if it's bearings, or bad quality turbine - you're screwed. Tends to happen a lot with frenchies... best to avoid French cars.
Yeah, I'm guilty of habitually babying that car, so it isn't surprising at all that there was lots of crud in the turbo. Something else that doesn't help is that when I bought it, I did a fair amount of motorway driving every week, but over the last few years it's mainly been short, local trips.
That's the main reason I went for a petrol car when I recently had the funds to do it. Got a 2019 Skoda Superb 1.5 DSG, and I find it quite interesting seeing what sort of revs the computer chooses to run it at. I know petrol engines always rev higher than diesels, but the difference is quite startling. Not that it's really noticeable, of course, since it's so much quieter and smoother than the ancient 1.9 TDI.
Petrol is good for a city daily/ short trip car. Diesel is better for longer distances. Or in my case, if you want to jump start a small sun, or have enough torque to be able to destroy your gearbox...
7G-tronics are rated up to 800Nm, I'm pushing 950.
I can't push my E-class too much, or I'll get a very expensive repair bill.
But yeah, engines have gotten a lot quieter over the past few years. My dad has a 2018 VW Touareg diesel and it's much quieter than my E-class, even before I modded it and made it louder.
Also I like the new design of the Superb, it's a mix between Audi A4/A6 and VW Passat.
I wonder, what kind of MPGs do you get in your Superb. I'd like to compare them to my hybrid C350e...
Mercedes claim I should be getting 2.2l/100km (128MPG), but I struggle to reach 4.7l/100km (60MPG).
I have no idea what MPG value I could reasonably claim on the Superb, since we've only had it a few weeks, and we've not been driving much.
I'm sure it's much less than what Skoda claims, and a helluva lot worse than the 2002 1.9 TDI Octavia gave me when it was in its prime. Back then, I could easily do 650 miles at motorway speeds before I got the tank low warning light, so that's something like 55 MPG in the real world. Not only is the Superb petrol, it's also considerably bigger and heavier than the Octavia, so I wouldn't be surprised if its MPG isn't much better than half that.
As much as I appreciate the need for reducing the consumption of oil, the whole official MPG thing is a little ridiculous. Something that annoyed me was that the Superb didn't come with a spare as standard (it has the well for one, but I assume the standard fitting is one of those stupid inflation kits), and I strongly suspect that was primarily a weight-reduction measure in order to improve the MPG.
My 7-year-old Samsung washer just shit itself.

Yep...
Goddamn...
Fucking...turbo charger failures ....so sick of my turbo charger failing. I told it to charge in a turbular fashion. Did it charge turbularly?
No.
Piece of shit.
