I recently bought a 2001 audi a6 2.7t Quattro, it has around 130k. the guy said he put new turbos from a newer year on it. I added a K&N air filter on it, I just replaced the alternator and took the whole front bumper off. I drove it for about a mile n a half after installin the new alternator. Then the car started to drive really funny. I would push on the gas and it would kinda bogg out and have no power. I took it to get the codes pull and 3 codes came up. P0103, P1113, P0741. Can anyone give me any ideas on what could be going on?

 

P0103-Mass or Volume Air Flow "A" Circuit High
P1113-Bank1-Sensor1 Internal Resistance too High
P0741-Torque Converter Clutch Circuit Performance/Stuck Off

Not the codes I'd like to see.

For starters have the ECM scanned with a Vag-Com because generic scanner can not read all of the Audi codes and you won't get the whole picture.

It looks like you may have left the Maf terminal unplugged and burned or pinched a harness somewhere and shorted the wires to ground.

The 1st code P0103 is the MAF it is located in the air filter chamber and has a large terminal attached to it. Follow it back with your hand into the other harnesses see what you find. Those sensors are all in the same area and may have wires in the same harness.
