TIL that VW apparently made a small number of W12 Touaregs.
Because what could possibly go wrong.
I'm going to bet they probably were still better than the V10 TDI Touaregs. I've read the horror stories of those beasts.
I was over at the VW store a few years ago, and one of the techs had an entire v10 powertrain out to change a turbo, or oil filter, or something.
The engine looked almost exactly like a Borg Cube.
A testimonial of a guy who owned one:
As a former owner, allow me to remind you of the basics:
- 5.0 liter v10 twin turbo diesel
- Electronically controlled air suspension with SIX INCHES of adjustable height with “x-tra offroad mode”
- Electronically controlled center AND rear diff lockers
- 4 zone climate control
- 2 full-time batteries - one responsible for accessories, one responsible for starting, but BOTH sharing responsibilities if the other failed (more on that)
Let me share some of the joys of owning one for exactly one year:
1. One turbo failed. This required dropping the entire drivetrain out of the bottom of the vehicle. ~30 hours and special equipment and a ~$1400 turbo later, it didn’t work right. And that was the dealer master mechanic “fixing” it. I won’t get into things like the dealer breaking and then re-installing the broken driveshaft, as I blame that on the dealer.
2. One battery failed. The one under the driver seat. The driver seat that requires a 17mm triple square socket to remove. Because one battery failed, a complex and untraceable decision-making process was performed by the vehicle and it decided it wouldn’t start with either battery but it WOULD continue to allow battery drain from various accessories. I had to replace both batteries ($250/per battery at Wal-mart rates believe it or not). One battery was under that seat, the other required 18 10mm bolts to be removed. EIGHTEEN.
I actually bought an aftermarket warranty that paid for $7k worth of work conducted in that one year of ownership. I then sold it - firesale style - and it had drivetrain issues.
I believe alternator, turbos, thermostat/cooling system work.... you have to drop the motor. And when I say drop the motor, I mean drop the drivetrain. And when I say drop the drivetrain, I mean use a special lift and tools that can handle the weight of an aluminum-block 5.0 liter diesel engine and transmissions.
Seriously, parts were scarce but the main thing that made me sell it is no one could work on it and even the knowledge base online was scarce. It was terrifying to own as a DD because you literally could have a part fail with no warning and struggle to source parts and a reliable mechanic to do the work within weeks.
That’s what happened to me—a turbo failed and it was two weeks and me running around to get it “fixed” and they still broke the driveshaft.

I was waiting to pipe in the same. The W8 is a camry (ok, maybe more like a 10 year old former rental car Malibu) compared to the V10 TDI. I still own one and just in the last 6 months it’s cost me $4280 (failed center drive shaft bearing, failed glow plug and had all 10 replaced).
I had to laugh at the ‘do you own an engine hoist’ on the ‘Should I buy a Passat flowchart’. Engine hoist, ha! You would be so lucky with a V10. The VW dealers all had to install special split fork lifts just to service Touareg V10's! As you pointed out the entire body has be separated from the drivetrain/chassis to do any engine or transmission work. I also had a failed turbo. That was also covered under an extended warranty that paid out somewhere around $10k before it expired. I only paid $1500 for it and it was bumper to bumper, $0 deductible, 3 years from purchase date. I was on a loss mitigation spreadsheet somewhere....
...Now that it’s out of warranty I have my own loss mitigation spreadsheet...

Ah, yes, the Touareg V10 TDI. One of the most interesting and horrifying Volkswagens of the modern time. Let’s take something hideously complicated – mostly for the sake of complication – and cram it into a half-baked SUV foisted onto the dealers and customers for beta-testing. Looking at the engine, one cannot help but be reminded of some of the more outrageous mechanical German military inventions circa WW2.
Apropos, if nothing. Insert joke here.
Many of the issues have been covered elsewhere – turbos, driveshaft center support bearing, glow plugs, many electrical issues, etc., so I won’t regurgitate. Actually, most of the electrical issues – keys and proximity sensors, tire pressure sensors, tailgate switch, gauge clusters, HID bulbs and the fragile headlight units – were Touareg problems as opposed to TDI-specific problems (minus the glow plugs, of course).
As I recall, the electronic turbocharger control module was somehow matched to the turbo and wastegate itself, so when one piece died you replaced everything as a unit. And, yes, the entire engine/transmission/front suspension drop out the bottom onto VW Special Tool #HolyCrapItsAnElectricTable for almost anything related to engine repairs.
We had two of those tables. Because Volkswagens break a lot. Oddly, the tables always worked.
Strong, fast truck, though, and one of the few vehicles I’ve driven that would noisily threaten to overpower its massive brakes. Which is something. Firewall the throttle, and the rush feels endless. You run out of road before you run out of V10.
Its funny that VW introduced the V10 TDI in 2004, then dropped the option in 2005 due to emission compliance issues before it returned in 2006. A bit of foreshadowing perhaps.
