DHP isn’t a must have on my list, but it’s not a no-go either. A 2020 just popped up that checks most of my other boxes (B&W is the only missing option) that does have DHP.

So, just wanted to ask if anyone has had any repairs due to DHP malfunction or if I should stay away from it as a second owner. Plan to daily drive it for 3-4 years and probably put 25-35k miles on it in that time.

Thanks for any insight!

I purchased a 2020 M550 with DHP a couple weeks ago so no help on this (and like you will daily drive it for the next 3 years or so), but curious as well if anyone has had any problems.

I don't have any hard data on failure, but in my two years of reading 5-6 G30 forums and groups daily, I have not seen one owner with DHP issues, repairs or warranty work related to DHP. I don't think you have anything to worry about.

What you need to determine is if you really like it. There is no off switch. I have seen a few owners that have it that wished they didn't have it. It definitely softens the ride and feel for the road because of the rear wheel steering. Some say it seems to float or pivot. Some people love this and some people could do without it.

75000'ish miles and no issues.

That’s the hard part. I haven’t had one local to test drive with or without it. There are two that are 3-4 hours away right now. I don’t think either is a real candidate, but I may bite the bullet and waste a day just to drive one of these and see what I’m shopping for.

I’m used to the base suspension on my 540, so I doubt it’s any less connected to the road than that. I could see it being nice on the interstate and on the two lane highway route I like to take to Nashville. Obviously, it’s good for maneuvering in parking lots.

If I end up with one that has 20” wheels, I may enjoy DHP softening that up a little.

Joe-BMW33 or anyone else, does DHP ride lower than the standard M suspension, or is it the other way around? I can’t remember which rides lower. That could be a factor for me. I know it’s a minimal difference, but I think if it lowers ride height that is a negative for me.

[Sam_M550i]

I've got DHP and love it. Drove one without it and that's how I decided I wanted it. 2 years no issues thus far.

Dynamic Handling Package is the top of the line you can get on the M550 for handling.
I do believe it sits just marginally lower than those without it.
I have it and at 14k miles, no problems.

I've read a few threads in M5 world where they swap out the DHP springs from M550's to get a smoother ride.

What are the packages, price and miles on the 2020 ?

Long story. Sent you a PM. Feel free to ignore if you don’t want to spend the time haha

On the M550 it lowers, on the 540 it raises it (go figure)

It is actually uncomfortably low, that’s my single gripe with it. I usually have to reverse into parking curbs. The front bumper can scrape some. I had the same issue with my ‘08 650i. Somehow not with an F82 M4.

It’s a scavenger hunt and a numbers game, personally I’d pick b&w over dhp if you wind up with that choice.

I’m not well versed enough here, but the rear axle steering actually seems to be an edge over the M5. There must be good reasons why bmw doesn’t offer it on the m5, though it’s peers in the Panamera and amg gt do have/offer it.

NGT2 - you already know my story but from my test drives I liked the passive 704 m sport suspension better than my m550 with DHP so I definitely suggest you drive one first. I was so hooked by the rave reviews that I even ignored what I felt on my m550 test drive and still got it bc I figured I must have been wrong and it was something else..

If you were closer I’d say come on over and drive mine. I am one of the few who find it floaty. It’s without a doubt more nimble but that also adds to the floatiness which is kind of ironic. I’m not a huge fan. But take it with a grain of salt, I have g05 40i loaner as my windshield is getting fixed and it’s just so relaxing to drive, soft, high up never have to worry about a pot hole or curb height. I much prefer it over the lower sedan. I’m trying to get out of my m550 and into an m50.

[Joe-BMW33]

I don’t think it lowers the M550 any more than without it. I don’t have any data other than knowing people that have it and I’ve never read (besides this thread) that it sits lower. People that are into lowering springs with DHP still get them. I’ve also studied many pictures of cars with it and they don’t look any different than without it.

430Scud , any insight here? If anyone knows, you would.

When ordering my car, I originally researched DHP quite a bit. Originally didn't include it, but after all the interneting and reading specs I ended up adding it in. I can't remember exactly where I read it but I remember seeing that adding DHP lowers the car by 10mm... sorta remember it was about 1cm.

For me coming from an Audi A6 which felt very similar to the 540i I test drove, it was the logic of DHP being necessary to offset the added weight of the V8. I unfortunately was only able to test drive cars without DHP, so I went with it based on internet research and how it made sense to me.

Now that I've had the car for a couple of months and over 2k miles, I'm 100% glad I added it in. The 4-w steering really helps with turning radius in the city and in parking lots... I'm still pretty paranoid about hitting stuff in tight spaces, haven't really got used to the dimensions of the car yet. While the behavior of the car at highway speeds is something to get used to, it feels a lot smoother and well planted than my A6. I usually use the driving assist features in the highway anyway.

Another thing DHP brings to the table is what they call active roll stabilization. Which is basically dynamically adjusted sway bars. For its size and weight, it's surprisingly planted when cornering... eats up exit loops for breakfast.

These points exactly sum up my own thoughts on the car's handling with DHP. I have put only a few thousand miles on it so can't say much about reliability, but the car now has 40k on the odo and hasn't required any DHP repairs (in the past or present). The concern about hitting curbs/elevated surfaces is real.

Totally agree. I've never had a car that corners like this beast.
The 4 wheel steering makes slow moving turns a breeze too.
I have a few favorite off ramps nearby where I can do at least double the posted speed on corners, and its effortless.

Same here, we have this banked looping overpass exit I use as a benchmark for how well the car corners. I first got the BMW bug in the mid 90's when throwing my friend's E36 at it... ended up replacing my recently purchased (but already bored with) accord coupe with a 328i.

Still use it to see how fast I can take it with every new car I get.

I have several stories like this too. Once, someone managed to keep
up with me all the way through one such off-ramp, quite unusually. They turned out to be driving an m2 comp.

My 2 cents

2nd owner a 2018 M550i with DHP & 20" rims. Picked up with low miles from 1st owner end of lease (14k miles). Only issue I had was the 2nd battery needed replacing right after purchase. Seems 1st owner did not drive it enough. Battery went bad. No big deal.

Love the DHP as well. Slow speed maneuvering when parking is great. As others mentioned sweeping corners with DHP make the M550i feel like a smaller and less heavy vehicle than non DHP.

I would purchase again with DHP.

[G30M]

DHP is the best thing ever

my M550i handles better than my M340i

very tight turns in town

eats high speed corners like a go kart

both of which my M340i can't do

(doesn't turn it into a track weapon as the heavy car does not like changing directions twice in a hurry - will leave track days - if any - to the 3 series)

can't comment on reliability ...

You used the word “planted” multiple times and that is a very attractive thing to me. I can get used to the changing lanes feeling I’ve read about with rear steering at highway speeds. What I love more than anything, especially at high speed, is feeling planted to the road as much as possible (while maintaining some comfort).

Are you able to test drive the car just to make sure you like DHP?
