P1857
P1857 is usually a bad MAF (mass air flow) sensor. You can find a bit more detail
here but that code is pretty consistent.

Audi a4 18T tubo model 2007 why does it mis only when it idils
It could be a few things, but my guess is a fouled spark plug. This could also be a sign of a bad ignition coil, clogged air filter or something wrong with the air sensor, or a major issue like a leaky head gasket. Start with the easy stuff like the air filter and the spark plugs. Also, try to borrow or pay someone to read the fault coded with a VAG-COM, at the very least it will tell you which cylinder is misfiring.

A4 2002 start up then stalls out.
There are several thngs that can cause this. Your best bet is to get scan your car with a VAG-COM and see what the trouble codes are. Most auto part stores (like autozone) will scan them for free, some smog check stations will charge you a small fee to do it, or, there is always the dealership. You can also check the VAG-COM locator to see if there is someone near you that will let you use theirs.

Climate control is dead?
It sounds like one of 2 things happened:1. You blew a fuse, be sure to check the fuse panel2. You knocked the power block to the climate control system loose. Check that the power block leading to the climate controll is tight into the control unit

Water leak
You may be overheating. The water pums have been an issue with these cars (Audi,VW). The impeller breaks and will no longer push water. This can be verified if you remove the thermostat and turn the impeller with your fingers (vehicle off of course). If you're able to turn it replace water pump, thermostat and timing belt.

1999 Audi A3 1.8T Electric Windows and Central Locking Won't work
will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.
