Hello, my name is ***** ***** I will be helping you with your question today. I've been working on Audis for over 30 years now, so I should be able to help you through this. Please understand that some of my suggestions may require special diagnostic tools and equipment that many home mechanics may not have, but are often required. So, my first question is whether you're planning on performing your own repairs, or are you wanting to be armed with information before bringing it into your mechanic?

Can I get two pieces of information from you please?

1) VIN

2) List of fault codes in Pxxxx format, or Audi 5-digit format?
