So thanks to the list I was able to locate someone locally with Vag-Com. Thanks much Alan!

My car started missing real bad yesterday and flashing the CEL. I got the following trouble codes, any idea where to start? It is a '99 A6 Avant-2.8 30V:

The camshalf adjustment faults have me worried. the car has 89,200 miles, I had the timing belt service done early- at about 70k, when the cam tensioner seals were leaking, and have not had any problems since. Any one have an idea of where I should start?

Thanks, Paul

first one sounds like camshaft position sensor is failing

...until you are certain that the belt is OK and the cams are still in time. The fact that both banks are complaining about cam adjustment could mean a problem with the belt. Cam adjustment issues will result in misfires too.

Yesterday I replaced a bunch of the vacuum lines (the little ones by the intake 5mm?) that were suspect hoping it would be the problem.
After I replaced the hoses I drove up and down the hill by my house with out any problems or miss fires, the CEL was still on though. I then drove it today about 6 miles to get the Vag-Com completed and results and it was missing so bad on the way home I barely made it.
But since it drove with out miss firing last night could that eliminate the cam timing and belt being off?

STOP DRIVING IT. If you have codes for cam adjustment you need to check cam timing immediately.

alos there is a possibility it is just a very low battery not able to maintain enough power to keep eveything at the right voltage.

I don't think franklins is getting it....

Shouldn't it throw a fault code fuel trim then?

Maybe so, do you live in Seattle?
