Seems that SDP do lots of common stuff available over here too.
wonder if owners of those vehicles have the same issues
The did the system for the renault scenic RX4 - must be pretty similar to the freelander one - permanent 4wd - mostly front drive
from a review of the RX4
"Designed jointly by Renault and Austrian four-wheel drive specialists Steyr Daimler Puch, the RX4's system uses a centre viscous coupling for front/rear torque distribution, and electronic traction control on the front axle. With these systems working in tandem, the RX4 can easily extricate itself from situations where grip is limited."

Is that the one where he says it cures 99% of all VCU problems and usually retails for 500 squid or something ???? hes avin a larf !!!
Anyway, got an initial reply from Jim at the Vanagon site
Heres what he said -
Chris,
There are a couple of places who "rebuild" the VCs by replacing their fluid. I'm not sure if I trust this as I don't know if they actually have the right fluid or know the exact proper amount to install. The amount of air left inside the VC when filled seems to be critical in determining its proper function. It seems the best way is to replace the VC with a new one. For the VW Vanagon Syncro the cost is about $1,000 in the US.
Another alternative (which I dislike) is to leave in the stiffened VC and add a "decoupler" device which is a manually operated way of choosing 2WD or 4WD from the driver's seat. It works well for off-road conditions, but neuters all the benefits of AWD for street driving especially in wet conditions. When installing a decoupler, some even replace the VC with a solid shaft creating a hard-lock between front & rear when the decoupler is engaged.
For much discussion of this you may join the Syncro goup at Yahoo groups and search our email archives with the terms VC or viscous or decoupler. Or, is this how you came to read about the VC in Syncros in the first place?
Best of luck.

I take his point about him not "liking" that option - but then we "dont like" VCU's which shag out either - Having a "switch" surely has to be a better option to knackering yo drive train or removing the prop shaft, which is the usual alternative?
As stated before - removing the 4wd reduces the load (to nil) on the VCU and IRD when in 2wd option and, with a good working VCU gives you back the normal condition. If you remove the VCU, it just gives the 4wd facility whenit is really required.
Be interested to know what "switch" mechanisms he is aware of - there is no need to re-invent the wheel! or indeed, the VCU

Latest reply from Jim at Vanagon
"SDP made a few prototype Syncros with a decoupler instead of the VC. Although VW never sold any like this, it established the idea for the de-coupler. Patterned after the SDP prototype de-coupler several entrapenuers with machining skills and some parts from VW have built kits for sale. In the VW Syncro, the de-coupler replaces the nose cone of the transmission where the flange to the driveshaft comes out. In the de-coupler nose-cone is the mechanism to de-couple the output from the transmission so that no power is fed to the driveshaft which extends forward to the VC, the fron diff, and then to the front wheels. While de-coupled the VW Syncro is a rear-wheel-drive vehicle.

Suppose the problem is -
If it cost say £1000 for one of these things, you could almost buy 3 new VCU's for that and given that the expected life for one of these is anything from 60K to 90K you would more than exceed the life of the vehicle ??
On th other hand, the unit would hopefully be a one off purchase and you wouldhave all the benefits of only being 2wd when on the road
Difficult one
