So, I bought a non running 2010 2.0t Quattro at auction for a ridiculously low price (I knew this was a huge risk). I replaced the battery because the old one was dead. All electronics have power but the car won't crank at all. Push the start button and NOTHING AT ALL. There were multiple lights on (ESP fault, EPC light, check engine, TPMs and more) so I ordered the Ross Tech cable. Scanned it and attached is what I got. The car was a repo so there's a strong chance that the previous owner pulled a fuse or relay to be spiteful but I haven't found anything out of the ordinary. All fuse box covers and wire covers were pulled off so someone was chasing a problem but that could have been the bank trying to get it running to get their money back. There was a GPS tracker in it but I removed that thinking maybe it had an immobilizer but not the case. Any help is greatly appreciated. I've searched high and low online for ECU relay location and I can't find anything. The closest I've found was close but not exact.

Have you cleared the faults to see what comes back as you still under voltage errors.
Have you checked the box under the windscreen scuttle panel; black lid- 4 screws- has more fuses in there with relays and also houses the ECM which the car can not see.... IS it still there??

Also, some say that new batteries need coding to the car? Not sure how accurate this is, as opinions seem to vary on the subject.

I didn't think of rescanning after the battery. I'm recharging now and will do that. The ECM is there but I can't get the correct diagram of the fuses/relays in there.

You wont see that in the manual.You will need to register on erwin audi and pay for an hour or more for access to wiring diagrams.
Some of the main fuses from the battery to the engine bay are under the small cover on the windscreen scuttle panel. they are heavy duty ones. check each one and also the fuses at the battery positive terminal under its cover.
As we cant see your airbag module at all i cant see for any airbag deployment.. check the battery airbag disconnector at the +ve terminal for continuity.

If you got a good deal on it, seriously consider selling after you get it up and running.

That model year A5 has lots of VERY expensive problems. At its current age, you're looking at a new engine and new transmission any day now. Find a 2013 or newer model if you can. Audi has lost MULTIPLE class action lawsuits because that engine is so poorly designed.

I would take the car to a good independent VAG specialist and ask him to sort out the electrics, to be honest.

We bought it with the intention of getting it running and selling for profit. We paid $2250 and other than this and some minor body flaws, the car is in great shape so we figured worst case we could come close to breaking even by parting out.

Yeah. But the problem with breaking a car for spares is that you need alot of work, space and time and then most buyers all want the same bits!!! Sure if the engine and gearbox are good then they are worth cash, same the wheels and the interior. And the complete front end including air bags, but that is NOT easy to take apart.

Best of luck to ya. If you can get it up and running without codes and without additional expenses, you've got yourself a good buy.

Which auction did you buy the car from? I might just buy one for a parts car in the future :)
