    . For me I’d still look at “locking pin” , if when selecting gear, shift travel need to be located in correct position in notch on selector shaft by the locking pin, if not when selecting 1st gear it may not be in perfect position for for selection angle, then will possibly crunch gears, also the position is picked up by gps ,this sinks with clutch position sensors in slave Etc etc etc, as for clutch they keep the same pressure over its entire life as it’s self adjusting. All links with smg electronics, in sink with pump solinoids controlling clutch and gear selecting process torque etc. I’m rattling on about spring and pin but this has a very important connection with what the gps picks up, which basically tells smg what’s happening, Also possibly why it’s serching for gears , once a gear is probably selected it should stay in gear until its told to change again,, Hope this helps

    Hi mate.

    He said that was all fine.

    The noise I’m getting he said is the dmf. It doesn’t happen all the time but when it does it pretty loud.

    It’s reverse plus 1st the crunching is happening and sometimes 1st is skipped too.
