the MAF doesnt always throw a code when it dies. in fact when mine died there was zero codes, no CEL for misfires, nothing. it just ran like crap. if your MAF has 100k+ miles on it it would be worth a replacement. the fuel efficiency i gained by replacing my MAF will pay for the replacement in about 9k miles. you can test if the MAF is bad by disconnecting it. if the car runs better without the MAF plugged in, thats your problem. which it probably is because of the P0103 code.

if it were a misfire the CEL would be on and flashing.

 

ok so i took it down to the shop. Now they are saying i have a shortage in my wireing harness and they want $250 just to find the short and then more to fix. what should i do? can i find it myself?

 

Do what ghost6303 said. Unplug the MAF first and see how the car runs. If it runs better than just replace the MAF.

 

if you have a multimeter or continuity tester you can do it yourself. download the assembly and maintenance procedures in the modification and maintenance sticky. it has instructions on what pins should read what ohms/volts.

 

Replacement jets? This I have not heard of... Where are the jets on an audi?

 

maybe it's his way of saying injectors????
