The CNRB has an updated and revised timing chain arrangement that is better than the CATA. And yes, somewhere the CKP-CMP data is available, but I think it isn't much of an issue with them, just that the oil leak repair requires you to take ALL of it off.

Unreal. Every time I see (or particularly when I hear) one of these late V6 cars go by, I think how nice they would be to drive.... Especially in an A6 or A7 rather than one of the SUVs. But then I read something like this and remember why I am sticking with the old belt-driven radial-pump 2.5L V6 for my "nice" car and the VE/PD 4-bangers for beaters. The 2.5L has its own flaws but nothing that can't be easily fixed, unlike this.

Kudos to you for being able to take it on and give folks an alternative to a dealer for this kind of work though, this is deep surgery. Can't imagine what the dealer would charge to address an issue named in their own TSB like this, IF they would do it at all on something this old anymore, and then the question of whether they could get it all back together successfully.

They aren't that bad... sure, if you're comparing them to an ALH or something, they are terrible (read, you can't neglect stuff or just drive it without ever having to do anything for 500k), but nothing like some people make them sound.

Here's a table to give you an idea of chain values & odo readings.

I've never been a big fan of the Touareg, mainly because I'm just not a big SUV person. But, as far as driving is concerned, the T'reg is nice enough to drive and they certainly handle better on the road than many others. They are heavy, and for us they are all AWD with slushboxes, which means they need something with some power to get down the road, and really all the engines they used are capable of getting the job done. The VR6s (especially the earlier ones) won't win any races but are certainly adequate. I think these later V6 TDIs do pretty good for power, but the cars are for sure far nicer to drive.... the Audi A6 is probably my favorite. Smooth, conservative styling, roomy, very refined, very nice to drive, and they eat up the highway with ease while using a minimal amount of fuel.

Here's a local unit if you really want to entertain it.... one owner, full records, good spec.... a little spendy, but private so you might be able to negotiate a few K off it if you really try

However, as OH pointed out, if you don't really need an SUV, with all that towing capability and ground clearance, etc, go ahead and try to find an A6 TDI.... they are fantastic, but super hard to find in decent shape or properly optioned.... but are also spendyer than the Touaregs while offering more features, better performance, better FE, etc. The ZF is way sportier\responsive than the Aisin, and the Audi "drive modes" really do make it behave very differently depending on what you select. (plus it's got stupid long gearing for hwy munching)

I've got one of each, and if I didn't need to tow heavy, the A6 could do it all for me.

I don't mind my Q5 TDI. Drives more like a car than SUV. It's probably 1000 lbs lighter than the Treg? It also has the ZF box.

Well the Q5 is a car.... it's the A4 avant with a shortened butt and a raised roof, essentially.

The newer (post-diesel availability for us) Q7 is the same arrangement. As is the Cayenne. And the Touareg is gone, we get the Golf 7 based Atlas instead.

Shipping info says 1300 pounds lighter. Which is about what I would have guessed. There is a boat load of metal on the T'reg.

Shoot, the giant transfer case alone, something the Q5 doesn't even have, is probably 100 pounds, LOL.

Well, think about the powertrain alone. The T'reg has a big beefy separate front axle and big chunky CV shafts, then even bigger and beefier of the same out back. The big transfer case I already mentioned, the substantially bigger and heavier steering and suspension components, bigger brakes, bigger wheels/tires, big heavy steel subframes instead of the thinner aluminum ones the cars have. Plus the obvious, the T'reg is physically bigger, in every dimension. It all adds up. Heck, even the wheel bolts are bigger! Probably also why in a drag race, the 3.6L VR6 Atlas would whoop the ass of the 3.6L VR6 T'reg.... not even close. I think the Atlas would give the V8 Touareg a run for the money.

Yes, it seems plausible. just surprising that it's that much.
Realistically, I've never thrown my egg on a scale.... so I've always trusted whatever garbage I've seen published as being somewhat correct when it comes to its mass.... I know it's a tank... it feels like one, it tows stuff like one....
I'll have to check my phone pics to see if I can find any dump run weights to attempt to guess at its weight.

Volkswagens (modern ones) are heavy cars in general. It stands to reason the T'reg would be very portly.

The real shocker is the Eos, LOL... those things can be closing in on two tons. That foldaway hard top with built-in sunroof is HEAVY, and the car needs all sorts of strengthening underneath as any convertible would. People can't understand why they spec 97 load tires. Small car, based on the Golf 5, but it's substantially heavier.

I realized how much bigger the Treg is when I worked on one a few weeks ago. It had been awhile, my belly could just barely squeeze between my compressor on the Treg on the hoist. Never a problem with the Q5.

I don't think the transfer case is quite 100 lbs. I lifted one recently to the floor and back in. The transmission is certainly a beast in itself though. I thought it was going to kill 2 of us setting it down on the floor from the transmission jack. I do like the press fit driveshafts on the T-reg though. Quick and easy to remove/install.

I guess my point with the transfer box is that, whatever it weighs, the Q5 doesn't have one. The "extra" bits for an AWD vs. FWD on the MLB cars' transmission output is probably about 20 pounds. That Torsen unit isn't very big. The later cars don't even have that, they use that little crown gear thingy, like a Haldex arrangement.

Probably worth pointing out that since Dieselgate happened, the Audi diesel offerings got stopped short of where they were going to end, and we sadly never got the A4 TDI. And since (for "reasons") we never got the 4cyl TDIs in any of the longitudinal cars like Europe did (most Q5 TDIs over there would be 4 cyl), the V6 TDI Q5 ended up being probably the best power-to-weight ratio of any TDI ever sold here. They flat out get with the program. Impressive to drive. Sad we couldn't have gotten the A4 with one. That would have been a hoot.

The Q5 sure does haul with the tune. I guess it is just pretending to be an SUV. In my younger days I swap engines to build what I want. Now I'm getting too old and tired for that. I was after a Touareg when the Q5 came from my dad's estate.

Q5 is probably much more practical than a Touareg for most people. Not as well suited for towing, but honestly, an F-250 is going to be more capable for towing than a Touareg anyway.

the size of the Touareg is perfect for our family's needs. two kids fit in the back and the dog behind them. i'm not aware (because i didn't look) of an SUV of it's size that isn't burdened with a third row. there is really no offering that compares to it. if it needs the chain done at some some point, so be it. totally worth it and i have a trustworthy indy. i don't lose any sleep over it's complexity.

Yeah, if you can afford it, they're certainly decent enough to drive and they are capable. They just can have some pricy services.

Here's one I'm working on now:



Just fixing a small coolant leak, LOL....

So here is the deal... usually, I will use big jackstands... if the powertrain is small enough, and I can fit it under, we also have a wheeled cart to set it down on. It can be tricky to get back placed right depending on what all you are doing. In the case of the VR6 above, I just needed to access the cooling system on the side of the engine below the intake, as well as had to remove the mount bracket which is also the oil filter housing. If this engine were mounted in a transverse arrangement as it was designed to belong in, I'd just take the front of the car off.

Here's an Atlas, with the same engine:



Much, MUCH easier to access (this one was getting a new set of injectors, because the Magneti Marelli sourced units are hot garbage)

I'd love to have the big bench, but it would take up so much shop space that it would become cumbersome.... we'd have to use the forklift to store it in the upper level.
