Hi daddiojiggy
From the images the sticker looks a little like Norton but I studied it closely and it's definitely Horton - the H is just a funny font that doesn't .jpg very well when using 30% compression.
Take a look at their web
site and you'll see Horton is a VFC manufacturer too - although why they sell Sachs VFCs is a little of a mystery! Maybe they have some kind of relationship?
Hi Phil
Good to hear from you again. I have top say I was a little relieved but you I were pretty convinced that it would all be OK - although I paid a significant premium by going to my dealer for the sake of this thread and of course the returns policy.
Regarding the VFC, it's dimensionally identical to my previous unit. MB never carried out a redesign across the range, only for the 119.974/975 engine - the EPC clearly shows this coupled with the 974/975 notes made here way back. Also, by MB providing me a VFC with identical part number '00 22' and dimensions this again demonstrates that no such redesign was made across board. The VFC and cooling design works PERFECTLY in the R129
so no need for change!
According to G.RAU (the bms manufacturer) the bending characteristics (specific deflection) are identical between this 'TB1577 A-GE-' and my previous 'TB1577 -GE' but in the interests of science it would be interesting to repeat yours or Jim's experiments.
I still have my old bms should any one want to try - Jim?
Two things that now interest me:
1. Who and how Horton fit into the equation?
2. That by removing the old cowl/refilling the VFC the cut-in point of the old VFC was lowered to 85C and therefore in normal driving conditions the VFC operated quite regularly
3. The R129 cooling system is as thought, designed to run at 90-95C in most driving conditions and in-fact it's quite difficult to increase it to 100C.
For those W140 drivers suffering temperature issues maybe there's a design issue with the rad?
One thing I want to correct is the previously hypothesised:

ALL VFC assys made with the bms marked as "TB 1577A -GE" will NOT lock up until 100C at the bms.

This is NOT strictly true and has been proved, so for those with R129.067 M119.072 cars your new MB VFC will operate perfectly keeping your cooling system running at a maximum of 100C (under severe driving conditions) and at 90C-95C for the rest of the time.
(Assumptions made - Ambient 20C)
