My T4 Syncro California Exclusive camper has broken down in Mexico. The drive belt broke and most likely the "Kurbelwelle". The camper is on the boat to Bremerhaven. I am looking now for a replacement ACV engine (2,5 TDI). I have ordered a new sport visco coupling ,500 Nm, from Kern in Austria. I am now wondering if I should have my gearbox overhauled. The garage in Holland says that if it works leave it. The gearbox however has run some 330.00 km and since everything has to come out maybe it is a good idea. What is the experience with the T4 syncro gearbox from 2001? What are the symptoms for problems? How many KM's can you normally drive with it. I expect to only drive now in Europe for a few years and then retire the camper.
My trip around the world is describe in Rudywelling.blog. Under Passepartout you can read up about the conversion from 2x2 to 4x4 in 2016 and on all the issues i had with the camper along the 160,000 km drive around the world. Clearly I was asking too much from this bus and outside Europe spare parts and good mechanics are an issue.
Looking forward to reading your advise related to the gearbox
