A6 2.8 1999. Codes on cluster 50...55...60...65....
 

Anyone know these codes. I'm the unfortunate one who bought this car cheap but put in 3,600 in the past year and I can bearly make out what it says on the cluster screen.

Codes on the cluster?? The cluster won't display codes; what are you looking at?

Yeah on my cluster that I can bearly read half the time it has codes. The right stick has up and down bottoms and you can see mpg the outside temp and on one screen it has those 4 codes that are coming up. My secondary air pumps no good. I have a temp sensor no good but the other day it went into limp mode 4th gear and a Audi tech said it could only be the trans range sensor. Cars been running and idling like crap

On the highway it did it the other night but once i shit off the car and testarted it the car reset. its been acting up for months now. The secondary air pump sounds like a jet and the temp sensor is also a code that came up. The guy who use to work for Audi that I know said it def sounds like a transmission range sensor but I was looking for more input since I get a min or two of his time cuz he's always so busy.
