Doesn't it seem ludicrous to you that a company capable of producing a car like the F10 M5 would intentionally do something that stupid?

The F10 5-series shares a platform with the 7-series, which was specifically designed to be quiet (among other things). There would be no way around that without significant (read: expensive) re-engineering. On top of that, the F10 M5 uses turbos, which makes the engine even quieter. BMW M tried all sorts of ducts to bring the engine sound into the cabin but couldn't achieve the effect they wanted, so they added a relatively simple program to the car's audio system instead.

I find it laughable that they had to go that route, too. I think it's one of the biggest strikes against the car, honestly. Let's just try to keep it real.

I'm not either, just as I am not a fan of water-cooled alternators as are in some BMWs.

IMO, the new CTS-V is exceptionally refined in everyday driving compared to the M5, IF we're talking about the last generation.

The new M5 is a techno bomb just waiting to explode! It even has water cooled PCM'S. Ludicrous complexity.

Unt ze name ist Stefan to you!

Nein, I can not endorse complexity that simply adds more complexity.

Having owned 4 BMWs over the last 14 years and an Audi for the last 6, I can say the BMW is mostly easier to work on.

The BMWs don't use timing belts, have much simper suspensions, and are generally assembled in layers that are straight forward if time-consuming.

But the Audi has fewer oil leaks to contend with, no goofy VANOs seals to replace, and have better interiors.

It's worth noting that many of the underhood components are exactly the same. The current e46 and A6 have the same alternator, electrical parts, even the exact same transmissions.

What's weird to me is that I get severely irritated when I have to work on American or Japanese cars. They aren't put together logically! It's like they just threw a bunch of [censored] under the hood and called it a day. Maybe they require less work, but performing the work just isn't satisfying. Under German hoods things are laid out logically, using a consistent language that is predictable.
 
Be careful when you hear someone lump all German cars together. My VW was [censored] to work on and parts were impossible to find whereas my BMW has been the simplest vehicle to wrench on I've ever owned and parts are always easy to find. From everything I've heard this still holds true: while BMWs have gotten more complicated just like cars in general Audis are monstrous to work on.

ETA: The V8 powered 530i is even easier to work on than my old 351 powered F150. COP and no smog system or EGR means there's actually more room to work around the M60 than the Windsor. How much this applies to a nearly new BMW I have no idea but take it FWIW.

I believe the question has been answered: BMW. I've owned 5 BMW's and do all the work myself. But I have older ones. 2000 M5 is my newest and then the 98 M3. So I'm guessing the newer ones are going to be more complicated...especially if you are looking at the Dual-turbo 335. My thoughts.

Not quite. He's looking at a 2010 model year. Neither the 3-series nor the A4 has an oil dipstick these days, but at least the A4 has a dipstick tube so that the use of an oil extractor is still possible.

You'd be unusually lucky to have a cooling system still intact by 125K miles in a modern BMW. Most start having issues by 80K or so.
 
Yea, all the plastic cooling parts and after run coolant pumps. I just never liked that they used a o-ring seal instead of a normal hose clamp for coolant hose connections.
 
The good news about both cars is that most of the failure points are widely known, and are very consistent.

So a new owner can do some research and PREVENT the problems that usually create the "nightmare" ownership experience.

We know that BMW expansion tanks, thermostat housings, and such all fail. So just change them before they fail and there will be no problem. It's a proactive philosophy, but it's kept my cars problem-free for a long time.
 
I absolutely love German cars! Always have. But they are like that one girlfriend that you still dream about sometimes. The passion and excitement was fantastic............but my god!! When they threw a fit, it was almost impossible to fix. High maintenence, and expensive to make it last.

In the last 5 years, I've become a Japanese car guy. Always there and very dependable. I like my new girlfriends now.
 
BMW. Audi's at their heart are VW's and VW does some really stupid stuff in terms of having to fix things.

I prefer working on good German cars, once you understand how they think they are cake to repair. BMW, Mercedes, and Porsche are all nice to work on. VW's and Audi's do their own thing and generally are not much better than GM.

So far my system has worked well for me.

It makes me wonder why you are considering BMW and Audi instead of Honda or Toyota.
German cars seem to have great engineering for the bits you see and feel and less than great in the places you don't normally see, while the Japanese cars are good but also consistent throughout.

I love BMWs but after 3 I think they are way too complicated and problematic when they get old.


Because they drive better.

An Accord can't hold a candle to a 3 or 5 series if you care about the driving experience.

No they aren't.

German cars are typically the exact opposite of that.

They'll use 3 different fasteners and two styles (ie: 2 different sizes torx and phillips) on one assembly. Blind assemblies one way fasteners made of ultra brittle plastics...etc... For a nationality that prides itself in manufacturing efficiency, one has to wonder what they were thinking. It took three tools to assemble this simple cover.

Then there is the indecipherable labeling. Is this the component I'm looking for? It's marked with an exclamation point and a schwa. What that's supposed to mean?

That being said, from a mobile electronics installer point of view, BMW and the Porsche 911 are the most "normal" (ie: most like Japanese and US manufacturers except the Porsche's ignition switch is on the wrong side of the steering wheel) Most Mercedes Benzes are fairly easy to run things underhood on. (amplifier power, starter cut...) Just remove the fuse box and pull out the plastic garbage bag full of sponges. You can stick your whole arm through that hole. Volkswagen and Audi tend to be a mess. The previously mentioned 2 different torx and various other fastener assemblies. Everything is wrapped in this greasy black fabric tape that will not stick to anything once unraveled. It will stain everything it touches but it won't stick to anything. And seems like every wire on a VW or Audi is multiplexed now. IIRC, they've had some problems with that with horns and stuff.

Lexus can be complex, but everything seems to be assembled and wired logically. Acura and Infiniti are comparitively easy.

Your rant applies to VAG products specifically but not German cars as a whole.

Perhaps you should isolate your complaints to VAG family products? As that's where most your criticisms appear to lie. BMW to work on, at least for me, has been as described by the person you've quoted: very logical with a specific "process" to do anything on the car.

No, BMW does use some unnaturally brittle plastics, blind fasteners, indecipherable symbols, and that wretched black cloth tape too, but once you get past the covers the wiring is logical.

I don't even know what kind of plastic it is. Maybe polystyrene. A similar cover would normally be polypropylene on a US or Japanese made car and you can snap it and unsnap it many times.
