Lexus NX Turn Signal Error

I had a similar issue with my Audi A4 a few years back. Same symptoms: error message, fault in the lighting. It turned out to be a corroded connector on the turn signal lamp. I would start by checking the connection, and maybe using some contact cleaner to see if that resolves the problem. Has the lens been damaged in any way?

Thanks for the suggestion. The lens looks fine, no visible cracks or damage. To clarify, was your Audi issue intermittent, or was the error constant? And did you try replacing the bulb before finding the corroded connector?

The error on my Audi was constant. I didn't bother with the bulb, as I had a similar problem before on a tail light. Given your mileage and the error codes, I would suggest taking it to a workshop; they will find the problem quickly. Seems as if the turn signal is defective.

Thanks for your help. I took it to the workshop, and you were right, it was a defective cable to the turn signal. They repaired the connection, and the total cost was 95€. Everything is working fine now.
