I HATE the new nav screen in Mercedes, even the £120k GT S gets it, looks like something you've got from halfords. My slk55 had it integrated into the dash, so is the Porsche.

I don't mind the bmw, looks like it pops up rather than just stuck on, wish it did pop up though.

So, my hunch about BMW making in-line production improvements to the suspension seems to be supported by some evidence.

This is based on looking at the parts listing for the vehicle on RealOEM.com, where I compared two vehicle configurations at two different production dates, as follows:

RHD F48 X1 25i (xDrive) -- as at July, 2015
RHD F48 X1 25i (xDrive) -- as at January, 2016
LHD F48 X1 28i (xDrive) -- as at July, 2015
LHD F48 X1 28i (xDrive) -- as at January, 2016

There are three possible spring/strut configurations for these vehicles (that doesn't mean these are available in each market!)
1. Standard suspension
2. MSport suspension
3. EDC/DDC/VDC suspension (ie, adjustable dampers -- even BMW seems confused as to what acronym to use!)

I haven't yet been able to find out the differences, if any, between the spring/damper rates of these -- it is just based on part numbers.

Thus far in the production cycle, the part numbers have remained the same for the standard and MSport suspension cars. However, from November 2015, updated front strut and rear shock absorbers entered assembly for EDC/DDC/VDC equipped cars identified by new part numbers. I can't determine an exact date for the changeover or the VINs; indeed, the parts listing suggests the inventory of superseded parts may have been used in vehicles with production dates as late as 4 January 2016.

What does this mean? Well, possibly nothing. But, given the harsh criticism of the X1's ride in original reviews and test drives, it does provide evidence that BMW took the feedback to heart, and has made suspension changes to EDC/DDC/VDC equipped vehicles built from 1/2016. That sort of bears out my comparison of the test drive vehicles I drove, and the EDC/DDC/VDC car I ordered, which was built on 18 January, and rides really well.

I could be wrong

That's an interesting find ttimbo!

I'm pretty happy with the ride myself. Just took it for a driving through some hills, on rougher kinds of tacmac with a few bumps. No complaints from me. Sure it's on the firm side when it hits bumps, and a bit of tyre rumble, but it's not what I would call uncomfortable. It's a fine trade-off for confident handling. I put it into Sport for briefly, that was definitely transmitting more surface irregularities through the car. The steering is slightly remote in either mode and bodyroll is well contained in Comfort anyway so I think Comfort is fine for 90% of driving and overall the X1 is a pretty good cruiser.

Interesting.....I was preparing for the fact that the msport would be almost bone jarring in "sport" mode after reading the initial reviews. Having just come back from 500kms travelling country (and dirt) roads, I found sport mode to be superb on the highway - tighter control and less movement at country highway speeds . Normal Comfort setting on dirt roads was surprisingly refined!

[ttimbo]

Indeed! Actually, my deduction from the parts numbering data and configurations is that if you have an MSport model in Australia (which includes DDC/EDC/VDC as standard), it has exactly the same suspension as the xDrive fitted with optional DDC/EDC/VDC. It seems you don't get MSport suspension in Australia, and by my reading, you can't get MSport suspension with DDC/EDC/VDC in any market. I now understand why our US owners are a tad upset with the ride; it seems they get the MSport suspension as standard, and no adaptive damping option.

The layout of iDrive controller has changed too.

A review of the Aust-spec 25i M Sport just published. A few inaccuracies - they mention M Sport suspension but I have checked that car's VIN via the rego and it does actually have DDC fitted. Now the review, once again, comments negatively on the ride quality, and the VIN reveals that car's production date was 28/11/15. So I wonder if this had anything to do with the suspension part change that you discovered.

Yes, that car would have been built before the suspension change, so BMW needs to get reviewers to revisit the car...a hard thing to achieve, no doubt.

Interesting the mention of "lag", which others have commented on (or is it the gearbox?) After 2,000 km, I've not noticed this. So, it's not as quick off the line as my M135i, but nor did I expect it to be. I'm wondering if this may have been addressed as well??

[PF1]

Lag is an interesting one. I can't say the car is lag-free. There is a small delay getting off the line, but I put it down to the car still being new and haven't really floored it yet. It's not as immediate as a non-turbo car but I've experienced the same sort of delay in say an Audi S3 with DSG. It is already a lot better than the lag on my Mercedes. On the move it's good and the gearbox kicks down promptly.

Does the Bridgestone / Dunlop seem better ride than Pirelli P7 RFTs which are standard 18" RFT ?

Hard to know unless you could test them side-by-side. My understanding is that the following are the likely RFT candidates that come fitted to the car from the factory:

17” Bridgestone Turanza T001-I RFT
17” Pirelli Cinturato P7 K1 r-f

18” Bridgestone Turanza T001 RFT
18” Continental SportContact 5 SSR
18” Pirelli Cinturato P7 K1 r-f

19” Bridgestone Potenza S 001 RFT
19” Dunlop SP Sport Maxx RT2 ROF
19” Pirelli Cinturato P7 r-f

If you have some time, take a trawl through the ETK.CC site and you'll see various components have EoP dates and SoP dates, whilst some have differing part IDs. Though I'd guess some of these changes are due to changing suppliers.

IIRC there are some part ID changes to the iDrive controller.

One noticeable thing on there is there is a common EoP around 2016.06 for a number of parts.

You're right... the part number 65829347470 was superseded in Mar 2016 by 65829371374.
