ok so this morning when i was headin to school i noticed my check engine light was on, on my 99 A6 quattro. so i went to autozone and they did a diagnostic and the codes came up as P1139 and P1137.

P1137, the description reads: Long term fuel trim add. fuel B1 system to rich
Explination: Failed MAF

P1139, the description reads the same as the P1137 but in B2 so what does this mean i have to get checked out?

theres also a little symbol on the display in the guage cluster that has a circle with letters in it that i cant read and a little 1 above it to the left. reason i cant read it is because the screen is going out.

any help would be appreciated..thank!!!

 

You can try to clean MAF and see if the code goes away. You will need a tamper proof torx bit, and a can of MAF cleaner. MAF sensor is locatted on top of the air box.

As for the symbol on the cluster, I think you are seeing the speed limit warning light. You should be able to turn it off by pressing and holding the left cluster button while the car is in motion.
