Sounds terrible. It might be time to get the Bureau of Automotive Repairs involved. Contact them at (800) 952-5210 and ask to speak with a BAR inspector. They will more then likely send a representative out to the smog station to inquire on your Audi's situation... this is assuming the shop is a certified California smog check repair station. If the shop is a General Repair station you may still get the BAR involved however they may not respond as soon as possible.
