Had 2 different trailers hooked up over the weekend, both 7 pin. I'd intermittently get the "trailer light Right (or left) turn signal module fault" warning pop up, but without the lights actually failing to work. Is it possible the connection is dirty? No changes to wiring, nothing wrong with the connector that I can see, and one of the trailers was brand new. Should I try a contact spray or something?

Not even a clue what the module would cost to replace, but suspect it's covered under my extended warranty.
