Has anyone had issues with suspension on LCI D3BT/ B3BT? Mine's a Touring and it's spent forever with Sytner in the last 2 years having issues sorted.

They've replaced all manner of things (bushes, shocks, anti-roll bars, top mounts etc, some more than once) and in general it comes back better than it went to them, but probably just thanks to a fresh spannering.

The last time it came back they were quite fed up with it, the message I got was a firm, "we've done all we can, the rest is a characteristic of the car"

Well now it's unhappy again. Symptoms are a crashy ride over uneven surfaces, what feels like a failure of the suspension to respond to sudden significant changes in surface (like coming off a speedbump) on the OSF a rattling over poor surfaces, all these get worse in Sport over Comfort.

As a comparison my wife has a 67 plate 118i Msport, it rides and copes better with any surface at any speed than the D3BT does, even when the D3BT is in comfort and the 118 is in sport, and the 118 has a full M-sport suspension pack and skinny runflats.

I've just had a rental 520i on holiday and it feels like a magic carpet ride compared to the D3BT.

So, am I alone or is this a thing? do I take it to Sytner (again) or, since Alpina's seem to be getting less and less reliable do I say sod the warranty and take it to a proper specialist in suspension to get it re-done.

*no selling it is not one of the options...

By "forever at Sytner" I think it's spent over 5 months there in 2 years for one thing and another, the Nav system is a bag of shite too, every time it gets an over the air update from BMW it deletes all the Alpina specific stuff and resets it to a standard BMW unit, I've given up on that one.....

I have to say my B3 is a rather firm ride when it hits a bump and it can feel like the damping isn’t quick enough to respond to the bumps.

I have had it checked out at my specialists and main dealer and they have found no faults. I then went out in a friends 335i with the same size rim and profile tyre and it was exactly the same. So it must be the 20 inch rim and 30 profile tyre.

It is strange as our B5 on the same set up was completely different over the bumps. I have learnt to live with it but it is annoying having to stare at the end of the bonnet on the look out for pot holes!

yes, I (and Alpina) blamed the rims, but I get the same issues with the OEM 19" rims and winter tyres. The shocks on the front of the Alpina F31 are off a 1-series not the 3 Series, but it's interesting you say you have the same thing. It's odd given the cars *should* ride better than a standard BMW, it's pretty much a key part of their USP.

Silly question time - Has the shocks/springs been replaced at any time?

I have a 2018 F30 D3 Biturbo Saloon with 20" wheels.

I've had absolutely no problems whatsoever with the suspension. In fact, its probably the best suspension that I've ever had in a car - Comfortable like a Mercedes but attacks the corners like a Porsche.
Of course, this is my subjective opinion and one person's definition of soft or firm can be different to somebody else's. I am personally very impressed.

Hi
I have the same issues in D3 Xdrive 2016 on the 19'' .
I have alpina for 3 months, and I'm really dissatisfied of this car.
Last 12 years, I always had BMW (E-46 and E91), and I was very pleased.
When i tried first time BMW F31 i felt in this car like in the normal car (like KIA) - no BMW. After it, I read a lot about 3 series F31, and read about ALPINA.
The conclusion in few read tests was: Better handling, better suspension.
I live in Poland so I couldn't test Alpina D3 before buy.
After 12 years with BMW, I couldn't buy another car than the BMW 3 Series
I bought 2 years old Alpina D3 Biturbo Xdrive without a test drive.
After 3 months of driving i can see irritate disadvantages
First bug is the suspension. Too comfort in comfort mode.
Too loud in sport mode. On the comfort mode stering wheel handling is terrible. I have to use sport mode in 99,9% of my driving. I have to change it always after engine start.
There is no option to change stering wheel sensitivity on the Comfort Mode like in G30 (Individual).
Second big problem is the handling 0-120 km/h. I can't feel the road. I haven't got any information on the steering wheel, like in e91 I had.
I do not have the pleasure of driving around the city, as it was in e91
Third Bug for me is the noise, Inside is 2,5 dB louder than in BMW e91.
Additional in light acceleration the transmission like use 2000-3000 rpm on the 1-3 gear even the car is cold. This is strange to me in diesel biturbo engine.
Besides, the car is beautiful and I like the look.
The interior of the car is well-made and polished, everything is where it should be.

Thanks for this, that's really helpful, mine feels like there's something not tightened up properly at best and like the shocks aren't working correctly at worst.

...Unless the F31 has a different suspension system because of xDrive maybe? I've never had any experience of D3 F31 estate so I can't comment on it.

Dans if you find yourself on the Isle of Wight then you are welcome to drive my F31 as a comparison. I've no issues, and what you describe does sound more like an actual problem as opposed to a differing taste in how a car rides.

Agree with this one, no problems experienced over the years, but would be interested if this was isolated or common with others.

Are you sure it is not the steering rack?

Lots of people on f30post.com were saying the same about their cars and it turns out there is a pretty serious issues with steering rack play that feels and sounds like suspension issues.
Far too much play on them.

Just a thought.

I'm not sure about anything, but the steering rack, ball joints and bushes have all been replaced.... as have the shocks, and top mounts and lower control arms...
