What is the best way to drain the gas tank on a 2003 Volkswagen Passat?

With a plastic siphon pump you can get at Harbor Freight, automotive, or any sporting goods store. Don't try to use the built in fuel pump, as it is too expensive to mess with and they are damaged if run dry. You can also remove the sending unit at the top of the tank and look in, to suck up any dirt or water.

Very slow to fill my 2003 Passat with gas. The nossle on the gas pump keeps shutting off as if the tank is full. It is not a problem with the gas pump as it happens anywhere I try to fill up.

Sounds like filler vent tube is plugged. Have a competent shop or dealer look at it, they'll either replace line or blow compressed air through it.

2003 VW Passat wagon 1.8 turbo, the check engine lite came on and the code is po411. how to fix without spending money I don't have

This code indicates that you have a faulty secondary air injection system. Basically this is a system in which pumped air is allowed into the exhaust system to help burn off any residual fuel droplets when the engine is warming up and thereby reduce hydrocarbon emissions. The 'injection of air' (opening of the valve) is by vacuum supplied by a thermally resistant over-braided vacuum line. Find your combi 'air injection' valve on the exhaust manifold and then check the integrity of the length of over-braided vacuum line. There is a good chance that the fault is merely a leak in this line (a poor end fitting) and this in turn is failing to supply the necessary vacuum to open the valve to allow pumped air into the exhaust. Hope this helps point you in the right direction.

Oil pressure stop motor

My 2003 1.8L Passat at 62K indicated Oil Pressure, Stop Engine. I had been low on oil for longer than I realized, though the car didn't indicate to me anything. I added a quart 5-40 synthetic as usual, and about 300 miles mid way on a road trip is when the warning lit up!
I had been to the dealer last year and there was a mention of sludge developing in these cars. They suggested I bring it in to remove sludge but life got busy, and it never happened. Evidently this model Passat is notorious for this oil sludge problem.
My Passat needed a new oil pump $800 later half way between destination and home. Luckily I was in a town with a 30 VW mechanic who was very good. The sludge (carbon deposits) had blocked pump pickup. Oil level was good. The computer didn't show anything, but the oil pressure test discovered PSI went down when RPM's went up. Not good.
This problem is very serious as it has ruined engines. I guess I was lucky in the fact that nothing else was damaged. So you may look into this build up. It sounds terribly familiar.

Need to find the part # on my secondary air injector pump

Hi Jeff,
I just pressed the "I can solve this" button but maybe I can't :-) All I can do from here is ask if you got 0410 or 0411? If so, maybe you don't have a defective $600 pump or $300 solenoid, just a cracked or leaky $5 length of air hose linking those items. It's common :-)

Cheers, D
PS If this merits a Fixya! - great; otherwise I'd be happier without a rating...
