Nah, no need for that. Just stick the transfer case in 4PT or 4LO and drive everywhere with it in one of those modes. Nothing's going to happen, right?

I currently have the part time 4wd light on when in 2wd. When it first happened I was changing out of Low4 to high2 & for some reason the PT4 light stayed on. As soon as I got back to the house (all dirt tracks) I jacked the front up & established that it was actually in high2. Checked all other settings & everything is just out by one on the lights on the dash.
Looks like the switch has slipped a notch.
Where is the switch? Near the leaver or in the t/f case?
Hoping its an easy job to correct.

Thanks WW.
I have no codes showing.
Now I know where it is I will check it out.

A bent shift fork can also cause it to show the wrong position, but that should only happen if you applied too much force to the shifter lever. The sensor is really easy to swap first anyhow.

Well no, that would be dumm. Okay since we have covered some seemingly legitimate used for 4FT, which I’ve always called AWD, then why would we want 2wd? Without locking hubs I don’t really see any advantage to 2wd. If anyone thinks it will use more gas or wear on components I’d like to see any proof of that as I believe it will not impact either significantly.

That's pretty much exactly what 4FT is - an AWD mode. It's one with a constant torque bias (48:52 front:rear, IIRC), but definitely AWD nonetheless.

I tend to agree - since there's no wheel disconnect, the front halfshafts are always spinning as well as the front driveshaft. Having said that: I also don't see a disadvantage to 2WD in most driving situations.

Given that the transfer case is disconnecting itself from the front driveshaft in 2WD, there is an argument to be made that removing the stresses of being coupled to the front driveline may relieve some wear and tear as well as save on fuel.

What I can say from experience with NP242s: I really haven't noticed an improvement in either one when comparing 2WD with 4FT usage. However, I'm also not typically running 4FT for longer than a couple of weeks, tops. This is usually during lousy weather, and I tend to set it and forget it until things clear up. Not going to count trail usage towards this, since that's a blip on the radar, comparatively speaking.

Hey....get back to shopping for your Touareg TDI over on ClubTouareg. [GRINNING FACE WITH SMILING EYES][GRINNING FACE WITH SMILING EYES]

It's on top of the transfer case. You might get away with a bit of grease on the plunger. Otherwise the easy way to replace it is to drop the case. I've been told that some have figgered out how to get it out with the case in place. With my recent tranny rebuild, it was a piece of cake with the case out of the car.
Good luck!

If that's a V10 Touareg, I admire his dedication.

Got to drive one of those once. That was one hell of a lot of fun.

You should look up the 2020 Q7 4.0L V8 Tri turbo TDI......of course not available in NA.

"Hey....get back to shopping for your Touareg TDI over on ClubTouareg."

Woverine,

You know, the more I look at them, the less I want one. A huge money pit, expensive parts, and nobody knows how to work on them. If I had the bottomless checkbook, sure, then you buy the Cayenne. But realistically, and affordably, the Jeep will do me. It'll tow what I need, better off road capability, and cheaper to own, insure,
and I can do some of the work on it. Doesn't have the bling/pose factor, but I can afford to run it. Four timing chains? vs $350 for a TB kit (Idparts has a sale on). On the V10 you have to pull the motor to change the turbos.
Cost me $350 for a tune, running good with the tranny fix. Total rebuild of the brakes and new tires < $1k with my trusted mechanic doing the work. From all reports the CP3 pump keeps running, the HDPF failure on a Tregg runs into multiple $ks. Shall I go on,,,,,,,,,,,,,,

Cheers

VW product is garbage always has been and the shift to “luxury” only made it worse. I would never own one for any reason. Why when you can have a bmw or mercedes or rover? Or THREE Jeeps?! Lol.

Hey WolverineFW & Rrusse11 I am not on ClubTouareg ! Has some one on that site pinched my name?

layback,
Not as far as I know, I have been posting a bit on Club Touareg, wondering about getting in to one. Too much of a unicorn for me really. Nice vehicles, but too expensive to fix, and nothing like the support you get here for the Jeep, or for my TDI over at tdiclub. Not enough built for any aftermarket support, and nobody knows how to work on them, outside of Audi/VW trained dealer techs.

Sounds remarkably like the KJ CRD ownership experience in North America

(BTW: we're also owners of a dieselgate-era Jetta TDi. Totally understand where you're coming from.)

BMW, Mercedes or Land rover? Lol....You can also find a laundry list of issues with all three of those brands without too much trouble, so let's not create an illusion that they are some how infallible.

Of course VAG group vehicles have issues as well, but I have owned three 3.0L TDI vehicles and still have two of them....two Audi Q7's....and the only issues I have had all relate to the emissions systems components that have been mandated of the years. I have fixed them all myself in my driveway. The Ross Tech VCDS scanner is quite powerful for the price.

They are no more expensive to fix really than any other luxury car brand. I have plenty of independent European mechanics that do quality work in my area if need be, but I have been able to fix any issue that has come up with the three 3.0L TDI'S that I have owned i my driveway without ever seeing a shop. You can download the entire shop manuals for $35.00 or something around that price.

Our little orphaned Jeep tractors are not exactly getting cheaper to repair on the motor side as parts are getting disconnected by Chrysler..

@Wolverine,

Well if you've got 2 Q7s in your driveway, then you're well beyond my comfort zone of "investment" in vehicles.
Lol, call me cheap, and more power to you if you can work on them. Guess I don't think the luxury class is for me , to each his own. I've got ~ $8k in my CRD, about the same in the Golf, but that's given 5 years and 60k of trouble free sevice, so it doesn't owe me a dime. With a hybrid turbo, a 26psi tune and lots of mods, it delivers extraordinary bang for the performance buck.

I agree the CRD is not a cheap motor to work on, but by the time I work that up, I'll still be less than the entry level of a cheap Tregg. Whether or not it's as long term a vehicle as the early TDIs remains to be seen. At least the Jeep I got is straight and rust free.

I'll cheerfully admit to not being much of a mechanic, at 68 I'm happy to pay the guy with the lift, though I insist on being allowed to watch and ask questions. Hopefully I'm an informed customer, and know what I want.

@casm,

I had a Mk6 TDI, nice car, but after I got rear ended and totalled, I took the money and bought an earlier model. No regrets! I can live without the "new & improved" tech. Keeping it simple is simply easier to keep running. With any luck and ongoing maintenance I'll keep both vehicles going for as long as I keep driving.

Cheers gents!

Well if anyone is still reading this thread regarding the original topic, another great application of FT 4WD, that I have not seen mentioned, is pulling a boat and trailer out of a steep / slippery ramp. A couple of ramps that I use regularly require some maneuvering to get into. The use of PT 4WD results in drive train bind. The FT 4WD makes these two particular ramps a piece of cake.

mrhemi,
Back on topic, I would have thought on any slippery surface, the PT would be preferred. And that the ability for the individual components of the drive train to slip some would alleviate any tendency to bind. Haven't been in precisely the scenario you posit. Haven't had the chance to launch my boat yet in these times of Covid, but it is certainly precisely the usage I envisage once I get a chance to test the Jeeps launching/retreival capabilities.
I'm also toying with the idea, in the best of all possible worlds, to be installing an Eaton torsen style limited slip diff on the rear axle.
