Looking at second hand diesels under 10k and some 535ds and a4 3.0 tdis are in my budget
What are anon's experiences with 6 cyl diesels, their reliability and fuel economy?

Preferably go for a 530d instead of a 535d. The 35d is twin turbo and they can be properly fast cars, but the turbo setup in them is a bit finicky and they had some issues.
530d is single turbo and they're million mile engines, not much to go wrong on them.
That is if we're talking about M57 powered 530 and 535d

The V6s are decent, it's the poor cylinders that struggle. My gf's parents have a diesel XF S that just refuses to die.
That said, the 6 cylinder diesels in general are just not as nice as the equivalent petrols. There was maybe a time around the late 2000s where they were a good option but not so much any more.
The supercharged V6 petrol in my XE is a far better engine than the diesel, it's the same with the B58 or the M-whatever it is Merc used in the C43.

Avoid all 35d (twin turbo N57) cars they are notorious for spinning bearings. My friend has a 435d and that needed an engine after 120k miles. My 2011 F11 530d has no engine or gearbox issues at 160k however everything else is slowly falling to bits.

>fuel economy
This really depends. If you rag them then you’ll get terrible economy, and most of the “performance” diesels have had a hard life in that end of the market because of it.
>reliability
See above. It always attracted strange buyers. It’s very “pub bore” type of people who owned them for the most part. If you are doing mega miles then just get a new diesel. If you aren’t, then buy the equivalent petrol. If you think you’re somehow getting the best of both worlds by buying a -35d you aren’t, because they’re not as fast as the petrols and because they are thrashed hard by the owners they usually need work. It doesn’t make sense as a purchase unless you are somehow:
>wealthy enough to regularly take a family on ski trips/centre parcs/etc
>but not wealthy enough for a Range Rover or equivalent
>performance minded that you want something fast
>but not too fast because why avoid the petrols?
>wants economy but ends up buying a used car with a hard life
>didn’t buy the new diesel performance because they are too expensive
You’re limiting yourself. It’s just a vortex of bad maths if you’re buying a used ~300hp diesel car because you clearly want something quick but mentally you want to “trick the system” by getting something that does 40+mpg. Which it never will, because you boot it everywhere trying to justify to yourself why you didn’t buy the equivalent petrol. Either buy the 3.0 petrol or if you must have a diesel get the one that’s actually economical and accept that it isn’t a racing car

im the same as you op, ecept with tripple the budget
>under 10k
>a4 3.0 tdis
as long as you have another 8k saved for the inevitable rebuild
b7 -> anemic
b8 -> trash gearbox, astronomic agr rate
b9 -> astronomic torque converter lag, DEF and agr issues
pick your poison
The last trouble free diesel was build in 07

This is absolutely correct. Modern 3.0 petrols aren't even bad on fuel. My XE S is on the thirstier side because it's supercharged and obviously Jag don't have the tech behind them that the Germans do, but it's still absolutely fine on longer journeys (40ish MPG, 400 miles to a tank).
It struggles with shorter trips and town driving or if I have a lead foot obviously, but so would a diesel. If I do put my foot down I get sharp throttle response, high revs and a nice supercharged petrol noise instead of sluggish response, no power beyond 4k and angry tractor noises

Never have there been more wrong opinions on diesels.
>significantly more reliable than the gas cars
>45mpg+/600 miles to a tank, youre not getting 40+mpg out of a gas car unless its 200hp to say otherwise is cope
>stupid quick with one simple trick and actually gains fuel economy/reliability when you do it.
Literally no other car can be a combination of as quick, practical, and cheap to run as a decent set up diesel. Perfect performance dailies.

claiming the type of fuel dictates whether something is "performance" or not means yorue a retard who doesnt know what they're talking about.
>>28851619
Even if we accept this as true, the diesel will be similarly fast and get significantly higher mileage.
>435d vs 440i
You know 440d's exist right? You dont even know what the BW R2S is yet youre trying to pretend you know what youre talking about.
>>
>>28851706
>similarly fast
But it isn’t. It’s a compromise. If your concern is fuel economy then why buy a performance car? You’re not buying a performance car at that point, you’re buying a compromise
When the 335d came out it was the car of choice for people who like to think they’re in the know, that they have an “in” that the rest of us don’t know about. “It’s just as fast as a 335i”. It wasn’t, it never was, and even if it was it was still a dull diesel with a rattle soundtrack that was out of ideas at 4.5k. It wasn’t as nice to drive as the petrol, didn’t make the power anywhere near as well as the petrol and was generally a nasty smelly diesel car for people that sold photocopiers
You’re doing exactly what all the first owners did. In your head you know something we don’t. You’re smart and you have a car that’s “just as fast” (it isn’t) but gets twice the fuel economy! What a winning manoeuvre. Except no one gives a fuck that you save £20 a week on fuel because it’s POCKET CHANGE and your car SMELLS LIKE A REFINERY and sounds like SHIT
>>
>>28851723
>But it isn’t. It’s a compromise
but it is, an M57 has similar stock turbo performance to an N54, & better than the N55. The M57 will get significantly better fuel mileage. An N54 will only make more power on stock turbos running ethanol in which case its going to get absolutely terrible mileage while the M57 sips pump diesel all day & is dead reliable ("reliable N54" lel)
Also whats wrong with compromises, or highly capable cars? I want to daily a fast car that gets great fuel mileage, is dead reliable, & is practical. A diesel BMW does all this very well. The equivalent gas BMW will absolutely fall short in one or multiple areas by comparison (fuel mileage & reliability namely)
>If your concern is fuel economy then why buy a performance car?
Because I want both, retard.
If a car is fast & gets good mileage, its not a compromise at all. You dont seem to know what a compromise is.
>It’s just as fast as a 335i”
Nobody has ever claimed this about stock cars. But a $100 JDB will make them similarly fast. With a tune and/or mods up to the limit of stock turbos the 335d IS as fast or faster than the 335i while being significantly more reliable. Except for aforementioned running corn on a N54 max turbo tune where youre getting 11mpg.
>it was still a dull diesel with a rattle soundtrack .... It wasn’t as nice to drive as the petrol
muh irrelevant wrenchlet europoor opinions lmao.
>that was out of ideas at 4.5k
thats fine because it shifts at 4750 & is out ahead of the more highly modified 335i
last run in this video is my buddies tuned N54 car with more mods than my "compromise" M57:

>You’re doing exactly what all the first owners did.
Youre doing what all the other sour grapes retard does & literally trying to invent reasons why diesels are bad because you personally dont like them. While having no actual clue about anything youre talking about
Post your car faggot, I bet you drive some 160hp fwd pile of shit lmao

i love my 5-cyl diesel volvo
it's not even that powerful (120kw 400Nm) but it just moves so effortlessly, like even somethinh ridiculous like 6th gear 1000rpm, it just pulls
diesel torque is something else
>>
>>28851870
I swapped from the 2.81:1 rear end to the 2.56:1 rear end from the DCT 335is because I made too many torks and 1st gear is ueaslessly short, plus I wanted lower cruising gear.
Now it turns ~1800rpm @80mph in 6th and will do over 60mph in 2nd and still will light up in 1st and 2nd without trying very hard.

Oh wait NONE of that is the case, never has been and never will be. No one wants a diesel corvette or a 911. There’s no diesel hill climb cars. Diesels aren’t desirable apart from among poor people who want to think they’ve got one over on people with a job making more than minimum wage
>>

>>28851336
Atleast in europe diesels dont make sense from economic side anymore.
Since some places do tax diesel cars more than petrol ones and in other places diesel is more expensive. So it makes economically sense to buy it only if you do long drives constantly

Also this is blatantly another poorfag busrider opinion feel free to prove me wrong with bread on hood of your car <|:^)

N57 aftermarket is coming up in the states. But I dont think it will ever match the big papa M57.

Its possible for there to be performance diesel enthusiasts in both the US and EUpooristan.
Its also possible for there simultaneously to be angry buttmad EUpooristanians who hate diesels while knowing nothing about them. As shown ITT.

My 330d was the least amount of time I've ever had a car (10 months)
It was nice but a very dull driving experience, it had a nice wedge of torque but never felt very fast and it was very agricultural.
To be fair the drivetrain was probably one of the better points about the car, the handling and steering feel in particular were shocking

My current 3.0 supercharged Jag is far better. Far faster across the rev range, much better throttle response, more refined and obviously sounds great in comparison

He's right, the American market is different. They have way more money, are way more consumerist, everyone mods their cars just for the hell of it. They are way less conservative when it comes to modifications, for example if you want steel pistons for the M57 you go to America. Europe might have better engineers in the OEM sector, in the aftermarket sector the US is probably the best in the world.

I have a 2010 A5 with the 3.0 TDI. I'd recommend it for a reliable engine. The main problem they have is the with EGR/DPF. The DPFs fill up and crack, leading to soot in the EGR which blocks off and overheats. Before you buy one check the ash oil level with an OBD reader. The max is around 700mL before replacement, but lower is obviously better. P0401 fault signifies a fault with this system but is very non-specific. Fortunately you can remove and clean the DPF and EGR in about a day from the top side of the car. There's no other way to fix it, ignore any of the snake oil additives etc. Also don't be tempted to remove the EGR, it helps the engine warm up quicker on short trips, I get to temp within about 10 minutes of driving which is pretty good for a diesel.
Fuel economy is excellent on the highway, I get just under 6L/100km. Around town it's still less than 10L/100km when I floor it absolutely everywhere (Audi driver).
Whether you want a traditional Quattro with the front-front engine is another question. I was also looking at a 530d and they seem like really nice cars.
>>
I have a 525d (2005) since 2010 and it still comfy as fuck. Zero regrets.
>reliability
I would say it's reliable. Even after these all years I can't really remember of a single instance where the car disappointed me.
>fuel economy
Mine is doing around 8-9L/100km.

luckily for Europeans, they add it at the pump. in America, they don't, so anything in the engine that expects lubricity additives will fail prematurely. Bosch CP4 fuel pumps in Fords is the best example of this.

not really. six pot too. cheap and accessible to everyone. most of the instances more reliable too with barely worse mpg. any diesel is a poorfag choice and youre coping buying a diesel bmw instead of a n54/n55/n58 or m car.
but hey, any premium german apparently is considered luxury in the us. in eu a bmw in our eyes is something like a nissan for you mutts.

M57 is a better stronger, faster choice than N54, N55 up to stock turbo flow capacity. Only exception is maybe an N54 on corn (hello 10mpg)
M57 will get better mileage stock and SUBSTANTIALLY better mileage modded for modded.
M57 will also be substantially more reliable modded
M57 is linearly the better motor choice stock up to around 450whp which is about the reasonable limit of power on the street.
If you want to make 600whp a single turbo N54 on corn is probably a better option but youre getting shit mileage on the edge of that motors bottom end strength with shit mileage. Plus you can just run a 150shot of nitrous on a M57 and it will take it all day and eat the N54's lunch.
There are very few practical situations where the gas alternative is objectively better. Mainly if all you care about is stock performance and are a wrenchlet that cant do a few simple mawds.
Also, nobody's claimed they are super luxurious cards retard. theyre just ebtter than the fwd 130hp shitboxes most euros drive and base their opinions of diesels on. Or the base model commuter spec one the retard here had:
