I've put photos of how I installed a 12,000 lb Mile Marker hydraulic winch on my (at the time) 6 week old D4, in case any one is interested. It is held in place by "Uncle Ray's" discrete winch mount, which had to be modified for this large winch's electrical:hydraulic solenoid. The winch is powered by the D4's power steering pump, and it works a treat. The biggest "gulp" of the installation is cutting into the PS system by the steering rack to connect the hoses. I suggest anyone who does this find a very competent hydraulic expert first. I tracked down the guy who maintain's Qantas's baggage loading equipment's hydraulic systems and he did it in about 15 minutes. One thing to remember about this type of winch is to be sure and disconnect the hoses (and re-install the piece that was cut out of the D4's PS tubing - now where did I put it?) before the body is lifted from the chassis. Could make a big mess otherwise I suppose.
The winch works a treat, but is slower than some may want. I preferred hydraulic for a couple of reasons. Firstly, it doesn't take much electrical power so the D4's computer/battery/gremlins don't even notice the winch. Secondly, there's no river crossings causing moisture and shorting out the electrics. The only electrics are in a small, sealed solenoid and the hydraulic system is pressurised (thereby keeping water out) as long as the engine is running. It is also completely silent when pulling, which is just plain spooky to me.
The winch rope holds the licence plate mount in place, and to do so I took off the winch hook. I just use a shackle instead. It does take a few minutes to remove the licence plate, and extend the winch rope, but for my use, a bit of extra time is more than offset by having the winch discretely where it is.Jim Dowell - D4 HSE TDi, 12,000 hydraulic winch & hidden winch mount, MTRs, TyreDog, Traxide 2 x aux battery system, fixed air compressor, Dolium roof rack, MitchHitch.

Neat install, are you not worried about winch blocking airflow to IC especially in Hot climate or prevent cleaning IC after mud section?A few mods... and keeping it all running...Faultmate MSV2

I was concerned about blocking the cooling, and did some experiments. I blocked the bottom of the IC/radiator with cardboard and drove around, watching the coolant temp, and listening to the fan. I was finally able to "force" a warmer radiator by driving on a soft beach for 20 mins with full tyre pressure (and full throttle) on a 40C day. As soon as I deflated the tyres to 18 psi, the coolant temp went down to normal. I love this type of scientific experiment
Regarding mud, hmmm. The rest of Australia refers to Perth residents as "Sand Gropers". We live on a huge sand box and while travelling 1000 km away it's still all sand. Mud hasn't been an issue. By pulling the radiator grill off, I can see the front of all the IC/radiator, so I'd know if mud or sand was sticking and then find a way of washing it out.
Blockage issues are the same irregardless of the winch being hydraulic or electric. I can't fully identify everything but suspect in the heat of Oz the D4 comes with a transmission cooler. I've no idea if we get larger radiators but haven't heard of anyone having an issue with cooling.Jim Dowell - D4 HSE TDi, 12,000 hydraulic winch & hidden winch mount, MTRs, TyreDog, Traxide 2 x aux battery system, fixed air compressor, Dolium roof rack, MitchHitch.

Is the South Africa cooling system the same as the european one? Maybe not as it could be bigger it would help cooling if acc locked radiator is an issue ...

so whats the impact on steering pressure when running the winch, I guess it wont need a lot of use on steering if winching; but do you see later on that maybe a new PS pump(upgrade) would be needed?
also can you show diagram of the connection as you wrote about putting back to OEM when going for service and I cant get the picture in my head how you have that set up
Nice work Experience is a difficult teacher, because she gives the test first and then the lesson afterwards!!!!
I haven't noticed any change to the steering when running the winch. That said when winching myself out of a hole, I don't move the steering wheel slowly. The hydraulic diagramme does show that the winch should take most of the PS system pressure to run it, so there's not much left for the steering, but I haven't felt it.
As far as an upgraded PS pump, I can't even see the existing pump in the 3.0 TDi engine, so I can't imagine changing to a more powerful one. There is someone else in Perth with a D4 2.7 TDi (the old D3 engine is in the base D4 here in Oz). He had enough extra room in the engine compartment to put in a much larger belt-powered pump for a hydraulic winch. However, I've no need for fast winching and couldn't find the space to put in a separate pump, so using the engine's system is okay.Jim Dowell - D4 HSE TDi, 12,000 hydraulic winch & hidden winch mount, MTRs, TyreDog, Traxide 2 x aux battery system, fixed air compressor, Dolium roof rack, MitchHitch.

Dingmark, your tests and lack of mud convinced me! The D4 IC is a improvement on the D3! A few mods... and keeping it all running...Faultmate MSV2
