Is a TDI that hasn't had the vw modifications done yet a good thing?

No

One side will tell not to have the mod done because VW will f-up the car.

-Reduced throttle response

• Lower MPG
• Uses more DEF
• Etc.

The other will say it is worth it if you get the extended warranty included with the modifications.

- Failed parts are expensive

I did the mod this year and it added peace of mind, it did change the driving experience.

Thank you for sharing! Follow up questions.

Is there a point at which the modification is no longer available because of mileage or model year?
A 2013 with 160K, what would be the warranty if the mod is preformed? 4/48, right?

 

[SaVAGeSoot]

I'd be shocked if you can still get it done, especially since you're not the owner from when it was a thing.

Call your dealer and ask them. I have a 2015 that was just modified l.

Yep. Touaregs only started breaking after the emissions fix. Unless it has stupid high mileage on it, in which case I could argue getting the fix would be strategic in that you now have a killer warranty on a high mileage car, which will buy you more years with it

They broke before the modifications, I had a 2016 that broke with 30,000 miles and was bought back by VW.

Not nearly as often. What exactly broke?

DEF heater and DPF

DEF heater and DPF

I mean those are somewhat common in any modern diesel with emissions... But they bought your vehicle back because of that?

The overwhelming consensus, across all modern diesels including heavy duty equipment, is deleting the emissions equipment results in lower fuel consumption and higher reliability due to lower temps with no regen cycles.

So, yes, the potential to buy a TDI that hasn't had the VW modifications done yet is considered a good thing.

They could not get it to run consistently without throughing errors.

It was the height of dieselgate and they made me an offerer I could not pass up.

$16K more that I paid for it after driving 43K miles.

I have owned diesels going back to the 80's

1979 Rabbit Diesel (48HP?)
198? Oldsmobile Cutlas Diesel
1988 Volvo 750 Turbo Diesel
199? 240 Diesel
2016 VW Touareg TDI
2015 VW Touareg TDI

The 2016 Touareg was the first modern low emmisions diesel.

A great vehicle. It was too bad it was part of the emissions scandal.

I looked at a GMC 3.0 diesel PU. A great truck, however, a quart of oil lost every 1000 miles.

That sounded like the next diesel disaster waiting to happen.

I found the 2015 Touareg with 44K miles for $21,000.

I could not pass it up. The AAC camera issue is all I have run into so far.

 

[SaVAGeSoot]

Don't worry, your eyelash will burn out soon and you'll regret this one too!

 

[RubberToe]

I don't regret any car I have ever had.
Each one is an adventure.

Now we can argue the point of extended emissions warranty with the modification vs better performance and engine life without it...

DEF heater and DPF

I've replaced loads of those on Fords, GMs and dodges (eco diesel). They are all the same.
Infact GMs had way bigger problems than most with their's even go as far as a recall if I remember correctly. Here's the tsb wording:-

"The faulty DEF tank heater may be caused by the tank heating elements being exposed to DEF and shorting to the pump ground."
Go figure...
Element cracked, def wicked through the harness. Def absolutely destroys copper and metal.

Yep agree. Cummins seems to have "fewer" issues but, still many issues.

 

[Dannyboy485]

Most Cummins engined vehicle use DeNoxtronic 2.2 units as it's a pretty generic DEF pump/metering unit and a bit more robust but more expensive and need more space to install. And they need their own ecu.
I've torn a couple apart in my time and even though there's "no serviceable parts" they are simple to recondition. I find the def line heaters tend to burn out after 3-6 years of service.

Interesting I had no idea! I reckon that could definitely explain my experience then
