Cheers for the advice guys. I was planning on writing to the DA already offering to sort it out, so this has pretty much cemented this plan of attack.
When I was arrested for the DUI I literally had 24 hours to find an attorney before leaving the country and the guy I went with seemed really good!
I found out about the warrant as I found the court website and was reading the details about my case. To say it was a surprise was an under statement.
