I bought my first 1999 Audi A4 Quattro 2.8 automatic a while back.
My first issues's:
On the cluster
speed odometer wouldn't work but rpms would
fuel dummy light stayed on
oil pressure gauge didnt work
I test drove this car 10 times before i bought it. Lol No problems from what i could tell.
Soon as i bought it pulled out of the guys neighborhood the car died. Cranked back up i guess it needed gas. So i got gas.
I drove it for about 2 hours awafterwards on the highway, no issues, sick car!!
Started trying to fix it...
For the longest time it wouldn't communicate with code readers up until recently.
Now i have went through 2 batteries since ive owned it for about a year or so. It didnt go many places just sometimes down the road.
When i would try to take a sharp turn it would die. Or like hitting the brakes and turning is the way it seemed.
I jump started it a few times. I think i blew up the computer.

Lights on dash:
ABS
SRS
check engine
it says Service (where the mileage is)

My codes are as follows
P1545
P1435
P1421
P1425
P1472
P1338
These are pending codes:
P0134
P0154
P1196
P1197
P1391
P1198
P1199
P0322

Is it possible for all of this to be wrong at once?

I had timing belt and water pump,spark plugs, wires, oil change,transmission fluid change, cam sensors (2), speed sensor, fuel filter, valve cover gaskets and alot more that i cant remember right now. Where is the audi god? Currently the car wont go over 5 miles an hour or less. I think its in limp mode.

Suggestions? Ive dumped 4500 in this car and now it wont even drive.
