I'm almost certain you are going to get a resounding NO from VW AG. That Golf uses a Haldex system (click here
for explanation from wiki) and I'm almost sure that it won't be able to be towed 4-down as the same system was used on our Audi TT which we once had that we wanted to tow but were told by VW/Audi that we'd ruin it if we did.
Volkswagen will give permission "behind the scenes" to tow any of their cars with FWD and a manual transmission ...that combination only. We've received written permission from them to tow a Jetta once that didn't have any notation in the manual at the time.
As Remco always says, the general rule is also that exact combination: any car with FWD and a manual transmission can --or should-- be able to be flat towed.
With that said, who knows if things have changed any since we've inquired. We'll be watching this thread to see if anybody is now towing a VW 4Motion with Haldex ...or if you do get permission from VW to flat tow your Golf R.
