The issue is that VW don't consider it to be a fault. I will be speaking to the dealer tomorrow, since the normal channels of complaint have obviously failed. I can tell you know it will be the last VW I will ever purchase
If you haven't already you should point out to them that the new Golf is sold on its added refinement and that in your opinion it clearly hasn't achieved that, as none of your previous cars suffered the same way. Hope you get a result, as you are the customer.
I'm also going to say that the Boron Silk products are of no benefit, even though am1w swears by them. They can offer no additional benefits beyond the standard gear oil.
.... and you know this from personal experience? 
Actually, yes. I was a bearing engineer for several years, a tribologist and lubricant expert for several more and I've researched and tested all the automotive lubricant additives including Boron Silk
. In my tests (using ball bearings, roller bearings and plain bearings as commonly found in automotive engines and gearboxes), Boron Silk additives did not reduce friction. Not even slightly.
In experimental tests, boric acid does appear to reduce friction under specific conditions. The sellers of Boron Silk have latched on to the apparent friction reduction properties of boric acid and done a (pretty poor) 'marketing job' with it. But they fail to mention things like the fact that testing was performed on components which had previously received a surface coating of boron carbide or boron oxide (which under the right conditions then forms a boric acid layer) applied by chemical vapour deposition. Your gearbox does not contain parts which have been treated in this way. Boron carbide is a ceramic and so if it was used in a gearbox would very quickly turn into grinding paste - not a practical solution I'm sure you'll agree.
More importantly, the tests performed by Dr Erdemir (who incidentally appears to have a business interest in Advanced Lubrication Technology Inc) show that the boric acid layer only survived for 600 cycles or so before it was gone. So even if Boron Silk could deposit a useful layer onto all internal surfaces (which it can't), it would last only 600 engine revolutions - at just above idle speed about 30 seconds. And then it would be gone until you changed the oil again a year or 10,000 miles later.
Now advances in nano-particle processing may one day allow a product which could reduce friction over the life of an engine oil, however at present the costs associated with that processing were it used (which it isn't) would make Boron Silk hugely expensive, which it is not. And of course there is the very obvious point that if there was a practical way of reducing friction with boric acid (which is commonly available as borax) it would have been adopted by, well, everyone. Particularly with all the emphasis on CO2 emissions reductions these days.
I have no qualms with you promoting a product that you personally feel is beneficial and might benefit others. However, you need to reign in the little "rolling eyes" sarcasm when someone else comes forward with an equally relevant but opposing point of view.
