***PROBLEM FIXED***
finally got to the bottom of the problem. I had it booked in to Audi for a health check and they told me about the light and the cost to repair was £1857.56, because the bulbs can't be replaced for repaired so the whole headlight needs to be changed.... yes ridiculous!
So i called the place where i bought the car from and they told me to drop it off and they will investigate.
Got a call next day and they almost gave up considering giving me a refund on the car.. but were going to try one more thing.. and yes its all good now.. that one thing they replaced was the Ballast.. the fricking Ballast which cost under £200.... WAKE UP AUDI!! AND STOP THESE LIES TO CON YOUR CUSTOMERS.
So if anyone has the same issue, here is your fix!
