2003 passat loses power

Answer 1

You haven't given many details, but I can cite a couple of possibilities that have happened to me. I have a 2003 Passat Wagon with a 1.8 Turbo engine.

If the engine suddenly runs rough and looses power, the first thing I'd check is one of the coils on the engine. Each spark plug has it's own coil as a part of the connector from the ignition system to the spark plug. I have had one go bad, and it caused an instant loss of power, and a somewhat rough engine (basically, one plug not firing).

I believe there is presently a recall on these. I keep a spare in the car since they are relatively easy to change. If needed I can give a few helpful hints.

Another thing that can cause a sudden loss of power is the large hose (approx. 3" dia.)on the drivers side of engine compartment that is attached with a large hose clamp.

If this hose comes loose power drops immediately. The reason this hose could come loose is that it needs to be moved out of the way when removing the oil filter from the top of the engine compartment. Could have been left loose.
