Hi, first post on the forum. I recently put my 2017 Tiguan SEL through an ARC car wash, I wash it this way maybe once per month. After washing the car a fault message appeared mentioning a left turn light fault. This cleared but the green LH indicator on the dash is on permanently. This clears after using the indicator to turn left, but returns after a few seconds. The indicator is very slightly slow to respond. I assume water has “got into the workings”somehow but seems most reluctant to dry out. I have had in the past the common problem of the orange warning triangle appearing on the dash during very wet weather, this seems to dry out quite quickly. Any help would be greatly appreciated.
