I've had 2 Allroads, the last one was just a few months ago.
Brilliant cars, but ... very expensive to maintain.
if you can get warranty on it via one of the extended warranty companies, then at least you would have that back up. That's what I did with the first buy.
in the end, mine went back because the garage renaiged on the repairs so I told them to shove it.
I bought an S Line in the end, nice, but not a patch on the allroad
