Moin Moin all, The following error codes have I turned off A1 114 circuit to program selector 124 program selector short-circuited against mass 322 incorrect transmission ratio A3 411 inlet valve left front wheel interruption or short circuit A7 122 temperature encoder pulse too long B5 222 air bag module Beef line interrupted 232Gurtstraffer right line interruption I have to say that I had developed the instrument to change the bulbs (of course without disconnecting the battery) since then the SRS light is on. Is now the Ltg connection in the combo broken or cable from the combo to the above mentioned consumers. Who has experience in this regard??
