Just a note on DFIS:
The guy that did pretty much all their VAG Bosch VE pumps, both the old ones and the electronic, passed away a couple years ago. I got the impression it was not sudden, like he may have been dealing with cancer for a bit. But he did his best to make sure his wealth of knowledge did not vanish with him, and tried to make sure some of the other folks there knew what was what.
It's sad, but it is a fact that a lot of old-school know-how in the trades is just going away. I've since had two pumps rebuilt by them, and other than taking a bit longer, the quality was top-notch as always, and I had no issues. I do think they are backed up with work, as many of us are.
As far as cost, EVERYTHING has seemingly gone up. And in the last couple years or so, substantially. It used to be ALH pumps were around $1100 to have them go through it, and one from Volkswagen was about $1500. So I quite often had the discussion with customers that for that $400 cost differential, I could get your car done the next day (in most cases), assuming Volkswagen had one in the Wisconsin warehouse (and they usually did).
Then, Bosch moved their facilities for VE pumps to Czech Republic from Germany, and the price went up... first to around $1800, then ultimately it went bananas... the current Volkswagen list price for a manual ALH pump (part number 038-130-107-KX) is a staggering $3702.73. Oddly, the automatic version (JX suffix) is only $1429.96, but those may already be on the NLA list.
Our local Bosch place, who wouldn't touch these pumps because they didn't have the proper test bench, ended up getting rid of their Bosch authorization status because Bosch prices on parts on the stuff they WOULD service had gotten so crazy that nobody would pay them to do anything anymore.
I suspect a variety of these factors is why DFIS is charging as much as they are.
I'm almost daily confronted with what I feel are jaw-dropping parts prices, all kinds of things, on all kinds of cars. Stuff that was reliably $200-300 a couple years ago, and had been in that range for quite a while, is now $500+ or more. Price an OEM ALH or PD valve cover. Tires that were $120 each are now $200. It's been crazy.
Then add in an obvious labor shortage... nobody wants to work, and the trades are largely at their breaking point... labor costs go up, because there are fewer and fewer people available to do the same things that need to be done. We've pretty much had an open spot here for years for a qualified tech... can't fill it. I can barely take a day off let alone a vacation, and people have lately gotten really downright pissy about having to wait for things, and the dealers are full of crooks and hacks.
