No, I never got it sorted. Shop owner changed his tune, said he did the work as stated on invoice - he was deliberately vague. I asked for some information on who did the rebuild of my transfer case (since on the second visit he admitted that it was not a Mercedes rebuild which he sold me on) and he was not interested in responding. I also asked for the serial numbers of the remanned transfer case and the new 4matic valve so I could check them with what was in my car but to no avail. They are not a member of BBB. I found that out when I filed a complaint with them. The BBB says MB Euromotors, 344 W7th, has the second lowest BBB rating possible D-.
