I love my A6 2005.. Colby has a lot of miles on him about 160K.

Hooked a computer to it and these codes popped up. I took it to the
audi service center, I didnt want to pay 230 for a diagnostic test knowing
that I had these codes already.. and they are very expensive.. Any takers
on what may be the issue and can it be fixed.

P0300 Random Misfire
P0305 Cylinder 5 Misfire
P0304 Cylinder 4 Misfire
P0306 Cylinder 6 Misfire

Defective Light Adaptive Sensor

It shakes horribly and CEL is blinking ..

How much will it cost to get it fixed, and is it worth it.
