Wonder if anyone can help with this one - I have an S reg sharan diesel automatic. Twice now after it has rained the gearbox suddenly dropped through the gears, into the red with the revs, then back to 4th gear, back down through the gears again. Next day works perfectly. Probably road speed sensor or one of the gearbox switches, anybody out there had this problem?
