I purchased a set of brand new genuine ‘dynablink’ wing mirror indicators for my 19 plate-the smoked version.
They wouldn’t work correctly,this was something to do with a change of module after 2018,they fit fine,just flashed out of sync-it did mention on the box that they were only suitable up to 2018,but like an idiot I thought that was an error and wasted £150.
Ended up buying the ‘osram’ version,which worked perfectly.
