Evening All,

Quick question, long story short, I thought the altenator had failed on my L405 as advised by the good old RAC but low and behold garage has established that it was just a dead battery which was good news.

Question is, car all working perfectly, just seem to have lost the one touch window up facility. is it a quick fix please? 2015MY.

Thanks

It just needs recalibrating (always happens after disconnecting the battery):

1. Start the engine.
2. Operate the window control switch until the door window glass is in the fully closed position, continue to operate the window control switch for a further two seconds.
3. Release the window control switch.
4. Operate the window control switch in the closed position and continue to operate the window control switch for a further two seconds.
5. Operate the window control switch until the door window glass is in the fully open position (one-touch down).
6. NOTES:
If the door window motor initialization has been completed correctly, when the window control switch is operated, the door window glass should move to the fully closed position (one-touch up) automatically.
If the door window glass does not fully close automatically (one-touch up), repeat the complete procedure.
7. Operate the window control switch once to the close position.

Thanks fifthhorseman, all sorted. Much appreciated.

Anything else I should know?

Glad that worked, radio presets may be reset but I can't think of anything else.
