I had a similar problem with an old Sigma lens on my K-3. Putting pressure upwards on the lens would break the contacts. I found tightening the 3 ring mounting screws on the lens fixed my problem. Obviously don't overtighten them but nipping them up could be worth a try.
I tried to tighten the screws, they didn't moved at all, so they seemed to be already tightened. So without making any try, I turned the aperture ring quickly back and forth, from end to end (lens detached from the body). Then tried the lens on the body and no problem from the last five minutes. There's something going on with that aperture ring. If the problem comes back, I'll send it for repair directly. Anyway thanks for this advice Flasher.

FYI, my K-1 doesn't have white dot issue problem in any conditions during my astro photography.
DSP Firmware Version : 1.20.21.09
Production Code : 2.2
Manufacture Date : 2016:06:24
I am using it for almost one month 800+ shots, around 10% of them is astrophotography with or without astrotracer, maximum exposure was 5 minutes and not a single hint in any photo of a so-called white dot issue.
For more info see my comments here: Does the Pentax K-1 also has the white dots issue during long exposures? | Pentax Rumors
I got them @ specific settings as I wrote. So it is quite strange.

Is the shutter count shown somewhere in EXIF-data? Now that I have taken quite a many multiexposures (about 100x frames per ME) the photo counter shows just photo counter. It was running at 1200 something while in reality it is more like 5000-6000.

Yes. There is even a utility link on this site that will read the exif from an uploaded in-camera JPEG.

Check Camera Shutter Count and Manufacture Date

I use ExifGUI. It seems to show the most info of all the Exif readers I have tried.

Use the MAKER tab on the right after selecting your photo. The shutter count info can be buried in the middle but is about half way down. If you use it a lot then right click on the shutter count and add to Custom View and Tag/Mark so it's easier to find next time.

Latest ExiftoolGUI version 5.16

Does the camera always end up in M-mode when the mode dial fails?
I haven't paid close enough attention to tell for sure but it does seem like that, or am i wrong?

I was just wondering, did you use the mode dial set to free move or push to move using the centre button?

From what I have read, yes. Mine first showed TAv even though set to Av, but that was only momentary. Then M, and that's where it has stayed.

I push to move so I don't accidentally bump it off.

Yeah, that's how I use mine. Thanks for the feedback, I've not had an issue with my mode dial so hopefully it'll stay that way.

No idea, which is why I am wondering what the process/response/turnaround time has been from CRK in Oz.

I have become VERY attached indeed to my K-1 and know I will hate being without it, even though I have a K-3 (or two) in the study!

The fault does point to something like a lose ribbon cable.
One could guess they use four bits to indicate which position the wheel has (4 bits gives 16 possible positions), and when the cable is partially off you get a faulty wheel position, and when it’s totally off the socket the camera reads all zeros (or all ones) which apparently indicates manual mode.
