Hi I'm a newbie to this sight getting my 1st 3.0 alphard in October I do know a bit about alphards as I work for a Japanese motor factor's that specialises in jap import parts if you got a traction control problem get the steering rack bushes checked if they have started to fail this will cause the steering rack to move and will inturn play havoc with the traction control not a expensive job to put right just need 4 new bushes pressing in .
