My Uncle had a V10 Touareg. Water pump began to leak and that requires engine removal as it's a the back of the engine. The estimate to bring that Vdub up to snuff was over 20K, plenty of ''while we're in there'' repairs were in that quote. He promptly sold it.
VW charges 30 hours for removal/replace!
People in their own garage with no special tools can do it in about 10 or so.
Overcharge much?
I can see if you have a bunch of toys and a proper garage for mechanic but this is not the type of stuff you do with a six pack and my mastercraft kit. You need air tools and whisky
back in the days, i worked at a machine shop where we rebuilt engines (among other things)...for a regular car (domestic, V6 or V8), you could drop it off at 8am and pick it up at 5pm...we'd pull the engine, strip it down to a bare block with every nut/bolt removed...acid bath, bore out the cylinder walls, replace all the main parts (cams, pistons, rings, bearings, gaskets, water pump, lifters, full valve job, plane the head if needed) and put everything back together in a day...ah, the good old days.
