How's it going guys. I picked up a A4 b6 from a salvage yard.
car starts but doesn't stay on. Was wondering if anyone can help me out here. I've noticed a oil leak and thinking it's the pan.
I'm also getting a couple of cels. P0300, p0301, p0302, p0303 and p0071.

I'm pretty sure that gap Looks like the radiator was pushed into the belt area
And looks like I need a new sai pump
isn't supposed to be there
Seeing oil from this piece as well

What exactly are you asking for help with here?

Google shows:
P0300 - Misfire
P0301 - Misfire detected on cylinder 1
P0302 - Misfire detected on cylinder 2
P0303 - Misfire detected on cylinder 3
P0071 - Ambient Air Temperature Sensor Performance

To get into any more detail than that, you'd need to scan it with vag-com.

Your'e comments on the images aren't making much sense so I'm not sure what you're looking for, but feel free to provide some more info!

Wow, where to start...

1) Just shooting from the hip, but I would start by removing the front clip and just inspect the underlying structural issues. My guess is the core support is busted and the bumper shocks have been pushed in and will need replacement. Both are sacrificial parts that are intended to protect the frame of the car based on my observation of posts from wrecks and one that my first A4 was involved in. Also, look for any bent suspension bits, stretched bolts, might even try and remove the engine and suspension mounts to see if they were bent.
2) Hard to tell much about the last 4 pictures specifically other than it looks like it hit something low, like a rock in the road, was pushed into a curb, was inadvertently "jumped" , other than your oil pan looks like it gapped from the block. Need to assess that pretty quickly and see it there is damage to the engine block. You may change your mind on fixing it. As far as the remaining stuff that is low and may need replacing that are low on the car: SAI, intake charge plumbing which runs along the bottom or the radiator, the radiator, condenser, and condenser lines.. Just start disassembling and put the damaged stuff in a pile. Again, you may change your mind.
3) I would ignore the codes except for P0071 which is and ambient air temp sensor which sits in front of the condenser. The other are misfires which may mean nothing at this point.

Final anecdote: if you decide to fix on your own, it will be journey. First step is to start tearing it down...

EDIT: Looks like 2 of us were typing at the same time. The suggestion of a VAGCOM would be critical to getting it back on the road...

Quite a project I think. You probably have a big air leak somewhere due to that front-end damage. As said, start taking the front end apart and see what you find.

Thanks guys. Will start taking it apart and see from there

So Im trying to get this running. Car starts up. But rough idles, as if it wanted to turn off. Giving gas will keep it on. And also putting it drive will steady it out. I have been getting misfire codes.
p0300
P0301
P0303
P0304.
I have changed spark plugs, and coils.
new sai pump because previous was crushed.
i noticed plugs were black and smelled of gas. And I get some white smoke out of the exhaust
I also changed the maf sensor.

What else can it be

Could I asked how much you paid for the car?

Are those the only codes that come up? Sooty/fuel smelling plugs imply that the fuel injectors are either leaky, or the ECU is getting an incorrect reading from the coolant temp sensor. If you have access to a VCDS scan tool, use that to see what the coolant temp is being reported as, and determine if that looks correct. Hopefully you didn't spend much on that thing, so try a new CTS.
