The AdBlue System on the 2016 Touareg has been a real pain in the ass. I’ve been to the dealership 6-8 times over the past 3-4 years. Sometimes leaving my Touareg there for weeks at a time.
Most of the time they have NO LOANERS!
Thankfully mine is still under warranty.
So the answer is NO... you are willing to give it up just to avoid the hassle of dealing with the dealer in exchange for free repairs.
Once you've deleted it, any other repairs that would've otherwise been covered will be on your dime. (and you will still need your own backup transportation)
