Hi John!
Long time no see on the board sine you left the 200 series. I sure miss your posts!
I know nothing about these cars but springs, as a general rule are pair matched as close as possible from the factory by batches. The steels temper can vary despite the shapes or lengths being the same.
So there might be a slight difference in the springs and color coding the lower and upper end tolerances.
It might be advantageous to some extent to make up for the continuous weight of a driver being in the car all the time over it being empty elsewhere part of the time?
Maybe the difference could be that it’s a replacement spring too.
Unless you bought the car new but I hope you haven’t been gone that long? Time flies!
I doubt you haven’t noticed them since 2007.
Are you having handling or loading issues?
These are painted on dots, right? They should be factory looking DOTS.
Not just spray paint.
If someone had them off, it does seem unlikely that a code like that would be used to put them back in.
Because that would require remembering what color went to what side?
The factory might have assembling training and for them to use a marking priority code like seems reasonable if it’s something like the scenario I laid out.
As you may remember the 240s put little bands and dash numbers on wiring sleeves to define production runs.
An example was yellow or white bands were on Crank Position Sensors. Yellow was considered older and more susceptible to failure, to Volvo mechanics and to us on the forum.
Just be glad you don’t have anything like a Nivomat suspension and be sagging!
Glad to see you haven’t forgotten the board as it gets pretty slow nowadays.
Phil
