Gentlemen, I have an 850T5 estate the other day the transmission refused to start from 1st gear through to 4th gear. When you pull away it starts off in
4th gear. Local dealer says it's the 'gear selector switch faulty or out of position'. Fault code 313. Has anybody had experience of this and is it possible to reposition/replace the selector switch at home under normal domestic conditions? Many thanks for any help!Paul
