Question about 2003 Volkswagen Passat
I have a 1.6 Passat and there is like an elcetricial buzz/humming coming from the engine when the car off. This can stay on until the battery is competely drained. Engine light has now started to come on. I was told taht it could be the fuel pump but I just replaced this a few months ago.
Look for the humming noise, sounds like a relay. Small black or grey cube.....then try to find out what it controls. Let me know where it's location is.

The flashing is telling you that the engine is mis-firing, the dealer will run a test to determine the cylinder that is mis-firing, chances are it is something simple

There are two pressure switches. One for oil pressure and one for a dirty oil filter. Are you sure you've changed the right switch. If car drives for 30 mls it doesn't sound like you need an engine. The spluttering is likely to be completely unrelated to the oil warning I suspect.

Definitely not the fuel pump. A fuel pump will either work, or it wont. It could be a fuel filter, though unlikely, again if it was clogged there would be nothing. Could be spark plugs/wires, a faulty coil pack, Could also be a handful of sensors (o2, MAF, are a few that come to mind). Does it have a manual transmission? If so can the car be started without engaging the clutch (in neutral)? If so check the 2 clutch sensors attached to the clutch pedal.
Probably a sensor. Go to Advanced Auto parts and have them pull the code. Then google it. Or check out Forums.vwvortex.com

get a new coolant temperature sensor.
the orginal black ones are faulty.
make sure it is the green topped one.
also do a normal tune up with spark plugs, clean the maf, maybe replace coils packs.

this is a common problem for these cars glow plugs go bad like spark plugs however the smoke would lead to bad mass airflow meter. it is not telling ecu corrcet miss. disconnect mass airflow meter. when cold see if this makes it start better. it should would means you need new m.a.f. glow plug issue take a test light place clamp on positive of battery then pull off glow plug connectors place tip of test light on glow plug the bad one will have a dull light unlike the good one which will be brighter. will need new plugs and wire harness four **** connectors and wire striper and crimper will fix concern good luck
