I have a 2000 Audi A6 2.7T w/Quattro. The car is putting out the following codes in this order:

Engine Codes

Transmittion Codes

Can someone please tell me what is going on and what I need to have done. The car seems to be a little ruff in the mornings on the startups. After a min or so she seems to run fine. Also my transmission seems to be sticking in gears sometimes unless I use the Tiptronic shift. Another issue that just started is that the EPC light comes on when I hit over 80-85 and my car goes into failure mode as the manual says and I have a huge decrease in power. If someone can please assist me with some info and maybe a possible repair cost, please let me know. It will be a huge help.

I haven't had the car long and I have had many things replaced including the ABS controler a few weeks back, the throttle body, water pumps. I feel like this car was in a flood or something because it's just one thing after another and it is getting hella expensive. Any advice would be great. The car has 65K miles FYI.

First let me say I'm not an Audi tech so take this post for what it's worth.
16487 = Mass Air Flow (MAF) High input
17521 = O2 sensor heater
17535 & 17537 = Fuel system too rich
17819 & 17831 =Secondary air injection flow too low
17965 = Turbocharger pressure control has positive deviation
17743 = Engine torque control limit exceeded

Sorry but I dont have the OBD codes for the transmission

Put all of this in a pot and stir it up and I think you will have a bad MAF and maybe some vacuum leaks.
hope this helps a little.
