Yeah, and then the independent will **** it up because of the tolerances that they will miss.
The only guys I would recommend outside of VW are V&N Workshop situated in Pretoria north. The techies there were at VW for 11 years until last year when they opened up their own shop.
The one serviced all my cars for 10 years while the other who specialised in touaregs did the wife's car. Good guys and very professional.
Another thing to consider is parts pricing. If the work is done at VW they get preferential part pricing which means that I wouldn't be surprised that the cost if the engine is R120k for an external party.
But the best thing about taking it to VW is that you get a nice year warranty on the engine etc. And R22k is reasonable. I cannot believe you think that a proper job with such a complicated engine (clutches that switch between the blower and turbo etc) and ancillaries will be R20k if it were a simple Toyota engine then sure.
FWIW the wife's tiguan engine replacement was close to R150k. But that was a new imported block etc. So get them to fix it if they put in writing its R80k. You have recourse if anything goes wrong.
But either way, it sucks to be in this position with a car that's only 4 years old.
