Well a few of us from here are on the Facebook group now so will have seen this, but for those that haven't I got the correct Lancia Multiair engine cover from Alfashop & here it is fitted. Part number is 55238563.
Yes, it has turning lights and a button to disable turning. Regarding headlight washers, I have still to see them working. Manual does not mention anything about them.. I will try to activate windscreen washers with headlights on to see if headlight washers work..
