In Germany Oettinger (and to a degree Abt) have a sort of factory backed warranty on their upgrades. In some countries where VW don't actually fully own the importer there are 'official' tuners.
Many years ago before VW fully took over the import franchise in the UK, GTI Engineering had fully backed conversions, but in those days you only got a one year warranty anyway. GTI Engineering's 'offshoot' BR Motorsport (BR= Brian Ricketts who was the engineering brains behind GTI Engineering split from them and formed his own tuning company) subsequently had SEATs backing back in the nineties for their conversions, not that they sold many.
I can remember from my days on cupranet back in the early noughties that Oettinger remaps were dyno proven to be very conservative next to the then recently emerged REVO, APR et al.
I think VAG increasingly steer clear of this stuff due to many obvious and probably some not so obvious legal reasons.
