Anyone upgraded the rear diff to a locker? If so was it done with OEM components or aftermarket.

I have an 08 V8 and living in Northern Colorado, I think it would be a wise play.

Will be good to know how and if this can be done. I wanted to buy the r50 but dropped the idea as they werent fitted with a rear locker.
As for the new 4xmotion Tregs they all come fitted with one.

Interesting question, but you would have to replace the switch on the console with the appropriate one, as well as find the correct settings in the computer to activate it I would think. Not so easy as just switching out the mechanical parts. This is assuming an OEM locker. If you found a company that made an auto locking kit for the Treg, that would be diff, however given the small percentage of Tregs out there, I doubt it is financially feasible to make.

I am looking at this retrofit, but I need the vcds scan for a comparable touareg with lock before I will be able to figure what needs to be changed.

Hope this helps....

Call an LKQ auto recycler. I asked and got a quote for 750. If I were to wire it up I'd use a different switch so you could engage it when its not in low range.

Thanks, but I need a whole scan from '08 V10 TDI w/RDL.

none of the V10s, as far as I know, at least here in Oz, from 07 onwards came with rdl. sorry cant help.
the scan above is from mine, which is 06...

Thanks for the info. That recycler is not to far from me. Now I need to find a reliable service center in the Boulder/Erie area that good on Touaregs.

It's a very simple solution actually:

1-find an 08 V8 with RDL
2-purchase above vehicle
3-sell current vehicle
4-engage rear diff lock
5-smile

Result, factory grade equipment change and potentially for no significant cost.

I agree that it can't be that difficult and you should wire it up seperately. Mainly becuase it is easier but becuase the ability to seperatly engage. Once I get mine running I'm going to be looking for a way to engage the locker when not in low range as well like I could with my old 80 series land cruiser. $750 is not bad at all really and I'm sure any competent differential shop could set it up.

Diff Lockers

Not being able to use the locker under normal driving conditions is a waste. I'm not sure what all parts are included for that price. I'm hoping they haven't had a bunch of calls and snap when I call. I need to figure out all the details and get a quote on labor.

Any recommendation on someone thats good with Touareg in the Denver/Fort Collins/Boulder area?

 

[yrktreg]

Already researched this. Search for more info.

It can be done but you need:
Rear w dif lock
Module for rear dif (rear ds cargo area)
Module for center dif (under pass seat)
Wiring for dif and rear module
New switch in center console.

The rear dif uses a step motor and is not as simple as simply giving it 12v which is why you need the module that has the motor drivers built in.

Great info, Thanks.

I agree with other posts about being able to select the lock under normal driving. One thing I would say is VW did a good job building the Treg. By the way whats the correct abbreviation for the Touareg?

 

[Mountain_Smith]

I'm confused why people are wanting to lock the rear diff under normal driving conditions? This should be the last thing you want to do. What am I missing?

I expect they mean be able to lock the rear diff when in high (normal) range.

Yeh I find it odd too..I suspect its really only useful in very extreme low speed offroad conditions. Moab comes to mind...I had it in my V10 and the only time I used it was in my driveway to see the light pop up on the dash. Kinda cool but whatever....

I remember asking the question a while back and nobody could think of a situation where you would NEED RDL to get over a specific obstacle.

Diff Lockers

Having the rear locker has a few benefits.

Rear tires wear even, instead of the right rear tire showing the most wear. No I'm not talking about doing i wheel burn outs.

Having one also lessen the use of the front axle, less maintenance. Less tire cupping on the front tires.

Not turning all that extra drivetrain helps with fuel mileage.

You don't have the binding in the drivetrain when turning on to a dry patch of paved surface.

Thats a few, less maintenance, fuel, and tires are the main items.

Aren't you talking more about a conversion to Part-time 4wd than a rear diff lock?

- Rear locker doesn't affect front axle, as front is controlled by transfercase. Your tire cupping is caused by something else.

- T-reg is full-time AWD so it will turn all drivetrain was there RDL or not.

- On full turn, binding is caused by AWD and each wheel travelling different circle (radius) and by that, all 3 differentials are running different revolutions.

On AWD, rear locker is useless on normal drive and usefull on low range.

I had front and rear 100% lockers on my old MB G and activating 100% rear locker on normal drive during the winter is fastest way to get the tail come around...

I share the boat with Mountain and Nick on this topic.
