Read evidence and context
Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Leading evidence: 'Replace mki and mkii iirc' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace mki and mkii iirc' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The orange tolerance code is throwing me. Can't find anything to confirm what orange would be. But you can clearly see the green spot on the shock which I believe means "sport".
I looked all the codes up about 4 years ago when I was getting ready to re-do my suspension. I thought M030 were green red green spots - maybe that's for C4 though... ?
My '99 C2 has green/red for the fronts and green/white for the rears. There were different color codes for C2, C4 and Cabriolet. They also changed for MkI and MkII IIRC. Having said that, I looked at the chart and don't see his color combo listed at all. Knowing his year/model would be a help.
I have a 2004 Turbo Cab. Bought with the current set up. I'm trying to determine what it is. If nothing else, out of curiosity. I have searched and searched. But no matches.
The 996 Essential Companion chart says M030 ROW front springs should be
pink
and blue for your car. It looks that's what you have but the pink has faded to look white. The chart has no listing for turbo cab rear springs.
The orange single dot on top is also a mystery.
I believe Porsche changed up the colors for identification around 2002. New blue (6.5mm front & 4.0mm rear) = old green, new orange (3.0mm/0.5mm) = old white for the dot at top of spring denoting compensator plate/disc.
Yeah... pretty much what I remember - utter confusion!!!
"Standards" with multiple changes and exceptions
In my case it didn't matter (and I didn't have the M030 anyway - except for the sway bars which are shared between the M030 and the C4 - green dot) as I wanted to lower the car a bit as well as stiffen it up.
Purely by coincidence, today I started digging parts out to resurrect a stalled BMW project and found that the valve springs have dabs of paint on them too. I can't help but wonder if there's a method to this madness. As in, is this some sort of 'thing' within the spring industry? Maybe just German thing? Who knows?
^^ Yeah it definitely is a "thing" - problem is, I don't think there are any universal standards, and even within companies there are so many variations it makes it difficult to really nail down what you've got - especially if previous owners made changes...
